- HuC6260 video: Fixed palette
- IDE
  . Words 57/58 of IDENTIFY DEVICE are total sectors, not sectors per track (machine\idectrl.c). As commented, this is the case for ATA-1, -2, -3, -4, and -5. The CFFA2 Apple II IDE card firmware relies on this value being as documented in the standards to properly detect the drive size, and none of the usual sensitive Atari/Midway games are broken by the change (This field is unused in ATA-6 and later).
  . Fixed for ide_controller_device class for most uninitialized variables.
- ISA: Commented com3 and com4 in isa_com implementation, usual case is 2 not 4 (machine\isa_com.c). Correctly mapped alternate port (machine\isa_ide.c). This makes a586 boot from primary HDD. Removed some legacy code from machine\isa.c. Added altstatus reset to atapi CD (mess\machine\isa_ide_cd.c).
- Konami custom chips: Cleanup (video\konicdev.h)
- Network: Removed mcast_chk and check for multicast in recv (emu\dinetwork.c, mess\machine\3c505.c, dp8390.c and mb8795.c). Set non-block mode for winpcap (windows\netdev_pcap.c).
- M6847 video: Changed the amount of scanlines on the 6847 PAL emulation. That said, the 6847 versions for PAL surely are doing more than this... At least laser1 on the MESS side works better.
- SCSI: Reimplemented the NCR5380 SCSI controller using nscsi (mess\machine\ncr5380n.c). Added 6-byte WRITE, logging of unknown commands, and some Apple-specific SCSI tweaks (emu\machine\nscsi_hd.c).
- SVGA: Just a few minor updates to svga_s3 (video\pc_vga.c)
- TMS9901 (Programmable System Interface): Avoid usage of uninitialized memory in tms9901_device::field_interrupts()

  . Added new gfx ($100002) rom to clone Tenchi wo Kurau (Japan)
  . Street Fighter II' Champion Edition: Fixed clone sf2m3 (boots up now, sound works and some gfx issues) and rom loading in clone sf2m8.
- deco_mlc.c
  . DECO MLC video driver reworking and scanline conversion
  . Renderer is now fully scanline based, should make implementing the raster effects in a clean way much easier.
  . Hide some unwanted gfx in Stadium Hero 96. Some improvement. Attempt fixing baseball rules in Stadium Hero 96, needs a lot of testing (Game now playable).
  . Added notes
  . Use extra clipping regs, improved doc.

  . Fixed uninitialized variables in machine\mega32x.c
  . Finally fixed topshoot and hshavoc in debug builds (machine\megadriv.c)
- megasys1.c: Reduced tagmap lookups
- megatech.c: Fixed Megatech loading in cartslots (image device does not seem to have access to the memory regions, so we have to pass through root_device). Better fix for Megatech cartslots.
- mcr3.c: Replaced M6809 CPU2 with M6809E in maxrpm and sarge
- mcr68.c: Replaced M6809 CPU2 with M6809E in archrivl, pigskin, spyhunt2 and trisport

  . Small fix on sprite enable
- naomi.c
  . Fixed some of the NAOMI regressions (the ones complaining about key pointer)
  . Added NAOMI cartridge encryption (machine\naomicrypt.c) and enabled USE_NAOMICRYPT by default. Note: The Naomi cartridge per-game keys are totally arbitrary at this point, let's not store them in 4 byte files as if they were dumps (by request / suggestion of Nicola).
  . Documentation cleanups
- neodrvr.c: Fixed MESS AES cart swap sound crash.
- nss.c, sfcbox.c and snesb.c
  . Fixed initialization of necdsp_device when no static_config is provided (cpu\upd7725\upd7725.c)
  . Let's try to untangle a bit the knots between machine and PPU
  . Some cleanups
  . Moved some snes stuff into the driver class
  . Further register cleanups
  . Removed a bunch of now redundant variables
  . Shuffling some code around. Other two statics gone.
  . Removed snesbsx driver: It never worked, and satellaview support will be done through slot devices.
  . Moved SNES add-on chips emulation to MESS
  . Some SNES modernization and cleanup
  . Updated the SNES driver to only save the real amount of SRAM present on the cart. This means that old .nv files won't be directly compatible with newer exe, but you shall be able to keep your saves by backing them up and taking the first block of the correct size (e.g. if you take the first 8KB block of your old .nv for Super Metroid it should work fine with the new exe). At the same time, MESS should be now compatible with saves taken in other emulators.
  . Added a missing open bus case. Experimental merging of snes memory handlers. Please test your favorite SNES games against previous code (or against latest release) and report regressions.
  . Split ROM/RAM accesses to cart in SNES slot implementation in order to simplify the code
  . Greatly simplified mapping and access for cart ROM. Given the massive internal changes, please test once again your favorite SNES games against previous code (or against latest release) and report regressions.
  . Removed the DSP1B dump from NSS, because planing to update NSS to use slot devices as well and that will cover everything needed by SMK, if we ever find its NSS release and dump it.
  . Temp fixed regression in SuperFX. The code is not optimal but it's going to be rewritten soon anyway.
  . Picked up a couple of copy & paste bugs with the pbr register in the SuperFX CPU.
  . Direct update handler is not being used in snes, therefore removed together with snes_ram variable.
- pacman.c: Pacman protection modernization
- pgm.c: PGM modernization
- pipedrm.c: Pipe Dream driver modernization
- psikyosh.c: Fixed corrupt font used for 'insert coin', 'game over' etc in Daraku Tenshi (ID 05122). Guess some refactoring changed the behaviour at some point, I assume this is what it was meant to be doing rather than trying to use a value it was in the middle of setting?
- scramble.c: Small cleanup
- segae.c and megatech.c: Improved triggering of 315-5124 IRQs
- ssfindo.c: Reduced tagmap lookups in driver
- ssrj.c: Added driver notes
- ssv.c
  . Reduced tagmap lookups in driver
  . Fixed visible area in janjans1, janjans2 and koikois2.
- stv.c
  . Actually fixed Sign flag in OR opcode (machine\scudsp.c). Added SCUDSP cpu type, though it currently only has a disassembler. Minor/Cosmetic change (machine\stvcd.c).
  . Moved some of the saturn code from mame\ into emu\ and made saturn.c & stv.c separately compilable. Still needs work before saturn.c can be moved to mess/.
  . Experimental fixes for Bug! (video\stvvdp2.c). Logging could be a good idea (added "A-Bus Dummy access ..." logerror).
  . Fixed for Choice Cuts crashing when skipping FMV. Fixed regression with Burning Rangers (drivers\saturn.c).
  . Fixed for file system printing (machine\stvcd.c), thanks to Firewave.
  . Fixed physical CD-ROM reading in CD Block, fixes Black Matrix FMV loading.

  . Improved protection in Steep Slope Sliders (machine\stvprot.c)
  . Final Fight Revenge ST-V notes (machine\stvprot.c)
  . Improved protection in Steep Slope Sliders (machine\stvprot.c)
  . Hooked up my theory for some other games, it's mostly right except it needs a decrypter expert (video\stvvdp2.c, machine\stvprot.c). Added a more sane ST-V SMPC Intback command emulation, based off Saturn version. Fixes inputs in Find Love.
  . Avoid logging if word reading from the IOGA
  . Added a more sane ST-V SMPC Intback command emulation, based off Saturn version. Fixes inputs in 'Zenkoku Seifuku Bishoujo Grand Prix Find Love' (Game now playable).
  . Virtua Fighter Kids trips this one (stv_vdp2_window_process(x,y)), hook it up (video\stvvdp2.c).
  . Fixed regression with Shienryu (machine\smpc.c)
  . Fixed protection check in Tecmo World Cup '98. Tecmo logo & Title Screen still garbled (Game now playable).
  . Fixed SMPC change clock behaviour, fixes 2 credits at start-up for various ST-V games. Might as well do the same thing for Slave CPU. Notes updating.
  . Basic hook-up of CD block command 0x64, pending actual transfer code (machine\stvcd.c).
  . Added hook-up for CD Block command 0x64 (Put Sector Data).
  . Fixed (MESS) Out Run booting, it triggers the RESET opcode and the only good theory so far is that the SMPC can read the RESET/HALT states on it in some way.
  . Actually ECPY isn't needed.
  . Attempt to added Copy Sector Data command, but my logic fails for some reason.
  . Actually found something that uses this, fixed (Wangan Midnight Dead Heat + Real Arrange, if you are wondering).
  . Death to window_control with bit pattern and old bitmap code.
  . Small fix for size allocation
  . Fixed filter reading on false connector (machine\stvcd.c).
  . Moved CD command timing around, fixed regression in logicpuz. Also added 11bpp bitmap mode for VDP2, fixed HUD in Tunnel B1.
  . Misc changes (machine\stvcd.c). Added SCSP sound clear (drivers\saturn.c).
  . Added preliminary CD Seek mechanism, fixes Zero Divide booting.
  . Default for ISM, there were some spurious irqs at boot (drivers\saturn.c and includes\stv.h).
  . Hook-up proper VDP1 fb erase via coordinates, fixes Gokujou Parodius / Sexy Parodius.
  . Debug code that slipped through (machine\stvcd.c).

  . First batch of real HW tests: added proper vblank firing (video\stvvdp2.c).
  . Actually fixed track seek, fixes regression with Zero Divide (machine\stvcd.c).
  . Splitted saturn and stv up a bit more so that stvprot.c is not linked into MESS.
  . Removed dependency as it no longer uses #include (mame\mame.mak).
  . Splitted mame\drivers\saturn.c into emu\machine\saturn.c and mess\drivers\saturn.c, so MAME doesn't have to compile and link the unused code.
  . Fixed VDP1 clear regression, reverted the blckmtxa attempted fix too.
  . Work-around for VDP1 framebuffer clear, fixes Daisenryaku Strong Style regression (video\stvvdp1.c).
  . Fixed regression with FAD end in track mode, fixes Death Throttle.
  . I imagine there is actually a logic flaw in the new code, but for now let's just stop it blowing up (video\stvvdp1.c).
  . Fixed stvbios loading in cartslots
  . First pass at improving CD get status command, fixes streamed music in falcom2, Wachenroder, World Cup 98 and probably others.
  . Improved previous fix, fixes regression with Road Blaster & friends.
  . Put the decathlete protection (compression) handling in a different file to the others, add some debug (disabled) code to allow loading of memdumps from UME/MESS for the title screen, will hopefully give us a good 1:1 match for some compressed -> plain gfx. This one is going to need a lot of work even once the gfx are done tho, currently looks awful anyway with the bad blending and 9% speed.
  . Bit of rearranging of the stvprot.c code with a view to easier dumping out encrypted / non-encrypted streams.
  . Further stvprot.c reworking + logging.
  . Timid attempt to make Pango Fun to boot and fixed ROM loading
  . Improved VDP1 timings, fixes several Saturn games such as Fatal Fury 3, Night Striker S and Command & Conquer.

  . Fixed game boot in Suiko Enbu (ID 03871)
- taitowlf.c: Reduced tagmap lookups
- vectrex.c: M6809 fix; Vectrex works now.
- yunsun16.c: Minor whitespace clean up / alignment
- Backfire: Reduced tagmap lookups
- Biomechanical Toy: Mark sample roms in clone Biomechanical Toy (Ver. 1.0.1884) as BAD_DUMP, the game code seems to expect different ones and they weren't dumped.
- Block Hole: Fixed bug in Konami/6309 16-bit NEG; clone Quarth is now playable again.
- Buck Rogers
  . Corrected ROM labels and locations for Buck Rogers and clones
  . Additional documentation for Buck Rogers: Planet of Zoom. Noted the encrypted Z80 part number and Sega ID numbers for the CPU and ROM boards. Corrected sprite color prom based on photo of PCB.
- Cool Riders
  . Fixed game (Game now playable). Cool Riders is a dual screen game, so give it 2 screens and take a wild guess at the screen select. I prefer to see everything it sends to the blitter. Use the 2nd tilemap for screen 2. Added different fake colours. Additional notes. Play with some of the blitter values a bit. Allow use of a fake ascii rom (hidden behind a define) (by request, so controls etc. can be hooked up). Palettes are written by the blitter as well, at least sometimes. this makes things worse in some cases, but you can see it's needed because the fades between scenes are done with it, I think DMA hookup needs fixing to match it, and possibly a palette select adding. Improved palette stuff + notes. Improved notes on some video stuff. Added some sprite compression notes from Charles & Andrew. Make use of some of the indirection enable bits I've found. Added some thoughts about the indirect LINE tables used by the main road draw blits. Notes on flip flags etc. Document 'blits' where the first sent parameter is '1' not '0' as non-sprites, probably clipping windows. More documentation of where bits are used. I think one of the blit params is a rom offset, so maybe it does decompress at blit time afterall, although for the ASCII parts that param is 0. Comment about likely rom offset bits / log changes. Some debug code, studying the compressed gfx. pattern observations note. Improved debug output to show 8 groups of 20 bits. Improved code to parse compressed data. Note of how the cell data (in compressed roms) references the actual compressed data (in compressed roms). Hey look, sprites. Kill fake ASCII rom, you can read the text now even if it's not perfect. Removed some old code. Expand the gfx data at startup from packed 10bpp words to 16bpp words(10 bits used) for easier / faster use. Kill some old gfxdecodes. Confirmed and implemented flip bits. Rotated object (map screen) and removed old debug code, will rewrite for further tests. Temp zoom code, to be improved / rewritten. Code reorganization. Fixed silly zoom bug with flipped objects. Looking at the road, not quite right. Better road handling, although less playable now because it renders over the bike. Added notes based on some (failed) test. Added some log notes from the clipping window commands used in places. Documented where RGB framebuffer controls appear to be. Experiment with when we do the colour lookup. Improved 256 colour decode part of RLE. Let's not mask out used palette bits. Put the object drawing on another thread, doesn't really help much, might revert later. Just part of a failed zbuffer experiment, will test a few other things later, this was nice in theory but isn't right. DRAW_PIX seems better. Better transparent pen handling. This is where it writes the sprite palette base. Code reorganization. Improved zoom handling. Looking at the clip windows, this is wrong, so disabled. Enable the clipping, improves attract mode, doesn't appear to break anything ingame. Needs to be signed. Improved tyres + brake lights (alt palette during decode - a form palette compression for cycling palettes while only storing partial palettes). Less aggressive application (render_object). Notes on clipping during ending, and a bit of a hack. Added tagmap stuff. Shuffle some clip checks around. Code re-org, I'll document this a bit better later, next I'll look at the blending. Some notes on what is likely the blending control. Slight change to the bg rendering, preparation for blending. Blending prep. Blending does not play nice with our z-buffer, road transitions and shadows on title screen have issues - will need a rethink. Make the flash effects full-screen. Prepare for sorting. Bubble sort instead of zbuffer, fixes most remaining gfx problems so I've removed all flags apart from the imperfect sound. Clean-ups. Better default inputs.
  . Basic hook-up of sound. More sound, it sends an irq to the master or slave. Check-point and added sound notes. Added inputs. Documented lamps. Comms works, sound still doesn't. Very preliminary sound DMA hooked up. Born to be Wild! Guessed m68k enable/disable. Changed some variables around. Added IRQ 6. Found a way to split irqs. Note update. Added scrolling. Fixed tilemap palette. Added SCSP sound clear. No more migraine inducting flickering. Code snippet for the ITI. Hooked up Backup RAM. And commented out DMAC while at it. Rewritten Tilemap DMA from scratch, and fixed data fetching while at it. Now the game properly clears palette when entering into test mode. Fixed text colors in Cool Riders. Yay, a game that more or less uses PROM mechanism in 1994. Fixed DMA mirror and removed hack. Tilemap rewrite. Added PAL data to the rumble. Make the transfers UINT16, saves some calcs and gives a speed gain. Tilemap rewrite once again, re-instated drawgfx, fixed second screen. Preliminary RGB ctrl. Tilemap vreg notes. Added command 0x30/0x34, used for solid pen fills. Guessed transparency pen select, fixes bike select screen. Applied RGB brightness on bike select, and fixed a silly bug on it. Fixed sound mirror. Fixed RGB for right screen, and attempted to guess a better algo for crashing. Added SH-2 internal SH7032 place-holders.
  . Added dualscreen (2x 496x384), 2x SCSP sound and left/right Speaker. Added 2x PLayers, paddle, pedal and 4x buttons and 2 coin slots. Removed AM9517A CPU. Added 'Use Threading Code' configuration.
- Demolition Derby
  . Added the "full" version of Demolition Derby that is dipswitch selectable between Upright and Cocktail mode. The other version was a only supported Cocktail mode.
  . Added proper dipswitch settings for the Cocktail mode only version. Replaced M6809 CPU3 with M6809E.
- Finalizer: Fixed bug in 6x09 DAA instruction; Finalizer (and probably other games) now handle score correctly (m6809\m6809inl.h).
- Fire Fox: Replaced M6809 CPU1 with M6809E
- Funky Ball: Fixed loading for the unused flash ROM
- Gunpey
  . Added irq cause/mask to Gunpey. Start of pulling up notes. Added OKI bank. Try to make a sense over the RAM format. Time to fix the irqs, game seems working but inputs aren't. Added text decoding. Fixed start buttons. Fixed X/Y offsets. Added timer for blitter irq and screen raw params. Added height & width. Added palette hook. Added 8bpp. Illogic beats logic 1 to 0, fixed hangs/inputs in service mode. Tied colors to drawing routines, and added transparent pen. Added end mark. Removed hack. Added basic scene hook-up and RGB brightness control, fixes credit display too. Identified RLE activation. Fixed vbl line.
  . Added GFXDECODE (just because we can). Start hookup of fake rom to Gunpey (not enabled by default). Various bits... F4 VRAM viewer. A mystery starts to unravel. Fixed text. H/W seem swapped. Better video rendering. Added notes. Fixed missing y source bits. Fixed logging typo. Misc improvements. Added missing x source bit. Commenting out some debug code. The first byte of the compressed data is the width of the compressed data stream in the texture page. Debug log was meant to be turned off for submission. Added data note. Make source x/y and dest x/y during the blitter copy more independent so we can treat compressed data as more of a stream. Definitely 9-bit wide LSB first as per OG's suggestion. Misc refactor for future work. Keep some of the more basic looking bitstreams (eg. char 959) aligned, although this is likely wrong. Added a note about the very first transfer, and some possible interesting facts. Reformat note with some additional info. Blending. Just some debug code to blank out data we've read from in a spare copy of the graphic rom region, although it already confirms what I thought, every byte of graphic data is transferred at some point if you test all characters, so no hidden tables lurking there. Rearrange notes a bit.
  . Removing unnecessary typecast. Fixed visible area and VSync. Added 'Service Mode' dipswitch.
- Head On: Removed nonsense 'Cabinet' configuration in B&W clones Head On (Sidam bootleg, set 1)/(set 2), Super Crash (bootleg of Head On) and Crash (bootleg of Head On) (ID 05145).
- Joust 2: Replaced M6809 CPU3 with M6809E
- Logic Pro 2: Fixed OKI sound banking and removed IMPERFECT_SOUND flag
- Megatouch 5: Verified clone Megatouch 5 (9255-60-01 ROC, Standard version) as a correct dump and removed the BAD_DUMP flag. Checked against 3 other sets and all dumped as the same. The issue with this set is something other then the data dump.
- Parodius: Konami CPU fix, Parodius works now.
- PinMAME
  . de_2.c
    . Adding a bit of meat to the bones. Still need to work on the MSM5205 and some of the LEDs.
    . Hooked up MSM5205 and fixed sample banking. Sound should now work fully.
    . Fixed sample ROM loading, got lower LEDs to display (but not perfectly).
    . Fixed P3/P4 area display for Alpha Type 2 games
    . Replaced M6800 with M6808 and M6809E. Added YM2151 and MSM5205 sound, Samples and 2x Speakers. Added Player 1 and 3x coin slots. Added 'Language' configuration.
  . s11.c, s11a.c, s11b.c and s11c.c: Replaced M6809 CPU3 with M6809E
  . wico.c: Fixed M6809 regression (slow sound) in Af-Tor
- Popo Bear
  . Fixed resolution and sprites are always square
  . Decoded tiles to a usable form and use drawgfx for the background
  . Use tilemaps, bit slow because of constant dirty marking in places, but still 400%.
  . Stop abusing 8-bit region for VRAM
  . Better layer enables / scrolling
  . Preliminary rowselect / linescroll for high scores
  . Sprite<->sprite priority handling (used to keep character line in order)
  . Changed how we handle transpen
  . Fixed visible area and maincpu rom loading
  . Fixed tile flips (game over screen)
  . Fixed for colours on Game Over screen
  . Marked game as working, the remaining issues (wrong animation speed / music speed) are cosmetic, it seems to work otherwise.
- Psychic Force 2012: Fixed ROM loading. Some minor changes.
- Rise of the Robots: Preliminary 53c7xx save state support
- Roc'n Rope: Fixed subtle problem in 6x09 CWAI instruction (m6809\base6x09.ops); Roc'n Rope is now fixed.
- Special Forces Elite Training: Added version 3.5 boot rom and added no_dump for Special Forces Elite Training PIC18C422 chip
- The Simpsons: Rewrite of KONAMI CPU core. Not sure about the Konami timings; they are definitly different from the previous core but the previous timings were a guess. KONAMI CPU fixes; Simpsons gets further now.
- Sukeban Jansi Ryuko: Added 317-5021.key from clone to parent set
- Track & Field: M6809 reset fix; resetting Track & Field works now.
- Turbo Sub: Fixed stack overflow in ESRIP disasm_disassemble. Replaced M6809 CPU1/2/4 with M6809E.
- Wave Shark: Fixed ROZ layer (K001604, video\konicdev.c)
- WWF Superstars: Re-Added old gfx1 rom to parent WWF Superstars (Europe). Using the Japanese FG0 rom on the World wwfsstar set makes no sense and cause glitches. This fixed Japanese text displayed in euro version (ID 05155).
- Dipswitch fixes in coolridr.c, de_2.c, fcrash.c, gunpey, harem, vicdual.c and wwfwfest.c
- Fixed rom names in arcadia.c, cps1.c, coolridr, harem, gei.c, mcr3.c, namcos2.c, pacman.c, scorpion and turbo.c

- Renamed (ar_ldrb) to (ar_ldrba), (ar_ldrba) to (ar_ldrb), (demoderb) to (demoderbc), (megat2a) to (megat2b), (megat2) to (megat2a), (megat3a) to (megat3b), (mtlchampu) to (mtlchampu1) and (starblad) to (starbladj).
- MAME
  . Fixed HLSL sliders and phosphor offset (windows\d3dhlsl.c and hlsl\phosphor.fx)
  . Changed CPU_DISASSEMBLE to use cpu_device * instead of legacy_cpu_device *, so that class based cpu devices can also be passed (emu\devcpu.h).
  . Pass this instead of NULL and options instead of 0 in the class based cpu cores (cpu\adsp2100\adsp2100.c, asap\asap.c, avr8\avr8.c, cosmac\cosmac.c, dsp16\dsp16.c, dsp32\dsp32.c, hd61700\hd61700.c, i8008\i8008.c, lr35902\lr35902.c, m6809\hd6309.c, m6809\konami.c, mips\r3000.c, sm8500\sm8500.c, tms32031\tms32031.c and upd7725\upd7725.c)
  . Modernize sound device (astrocde.c, beep.c, c140.c, cem3394.c, cps3.c, es8712.c, gridlee.c, k051649.c, okim6258.c, polepos.c, redbaron, rf5c68.c, rf5c400.c, saa1099.c, st0016.c, taitosnd.c, tiamc1.c, TMS36xx, TMS3615 and zsg2.c)
  . Modernized driver (chinagat.c, gomoku.c, neodrvr.c)
  . Modernized device (mos6526.c, mos6560.c)
  . Drivers cleanup (drivers\asuka.c, drivers\fastfred.c, drivers\trvquest.c, includes\actfancr.h, includes\asuka.h, includes\copsnrob.h, includes\dec0.h, includes\dec8.h, includes\deco32.h, includes\fastfred.h, includes\galivan.h, includes\gameplan.h, includes\nmk16.h, includes\spbactn.h, machine\bonzeadv.c, video\fastfred.c and video\gameplan.c).
  . Added another missing 32->64 bits conversion when building the invsubmask (emu\memory.c). Use proper free function for address_space.m_direct (emu\memory.c).
  . Removed runtime ioport tagmap lookup when using PORT_CONDITION with PORT_BIT, used by gmgalax for example.
  . Support up to 32 buttons and harmonize Windows and SDL behavior if you exceed the limit (emu\input.c and windows\input.c).
  . Don't save out internally determined settings to .ini files (emu\emuopts.c). Slightly clearer and safer. Re-evaluate slot options after loading .ini files in emu\emuopts.c. Be a bit more fine-grained in when to mark slot options as internal (emu\dislot.c, emuopts.c and lib\util\options.c).
  . Clear 7z file cache on exit (emu\clifront.c)
  . ROMLOAD
    . Fixed loaded rom percentage going beyond 100% with softlist entries. Previously, loading from softlist was using the bios romsize as totalsize to load, explaining both the erratic percentage values in systems like AES and the totalsize = 0 error in NES and other bios-less systems, which was requiring a special workaround. Handling is still not perfect (e.g I think that first the bios is loaded and counter goes to 100%, then the cart is loaded and the count restarts from 0%, so it would be better to have a separate message for the softlist loading, but I need to study in depth the code before such a change), but it's definitely better than having AES carts loading up to 12575% or NES skipping completely the soft percentage due to totalsize =0.
    . Reset rom size counter when starting to load software
    . Attempt to improve loaded rom percentage display. Namely, with this change the emulator displays first a "Loading Game N%" while loading MAME game or MESS system roms, then it switches to "Loading Software %N" while loading from softlist (this also applies to Megatech, ST-V and NeoGeo lists in MAME). I'm not completely happy with passing a "from_list" boolean to modify the behavior, but I have found no better solution. If you find any, please be my guest and replace this solution with yours.
    . Lists have no BIOS flag, so this check is redundant
  . Optimized info_xml_creator::output_switches() (improves -listxml speed in DEBUG build by about 40%) and optimized -listxml
  . We have a policy for naming conflicts. The suspect is, some of these are from dumpers being lazy and incorrectly naming things to fit the existing romdefs mind you, others are bootlegs where there are no real labels (drivers\8080bw.c, bestleag.c, dynduke.c, funworld.c, galdrvr.c, gei.c, headonb.c, legionna.c, mystwarr.c, nbmj9195.c, pacman.c, phoenix.c, segas16b.c, seibuspi.c, sprint2.c, srumbler.c, suna8.c and wecleman.c).
  . Windows OSD / stdout/stderr output buffering (osd\windows\winmain.c)
- SDLMAME
  . Don't include GTK+/GConf in Qt debugger builds (sdl\sdl.mak).
  . Make Ethernet pcap work on Mac OS X & disable unnecessary packet filtering.
  . Do Mac filtering in sdl\netdev_tap.c. Filter packets try 2 (sdl\netdev_tap.c).
  . Updated the traditional missed file (src\osd\osdnet.c)
  . Make the Qt debugger the default for *IX and Win32 builds (sdl\sdl.mak)
- MESS: Silencing clrmamepro. Fixed repeated descriptions.
- Compiling
  . Added missing virtual to device-level overrides (cpu\psx\psx.h, machine\tms9901.h, machine\tms9902.h, sound\bsmt2000.h, ics2115.h, qs1000.h, sn76496.h, tms5220.h, votrax.h, video\k053250.h, machine\jvs13551.h, k573cass.h, zndip.h and znsec.h).
  . Modernization of drivers M - Z (drivers/includes/machine/video). Removal of not needed machine().root_device() (MAME drivers A - Z; drivers/machine/video). Some atari modernization (atarigx2.c, atarisy1.c, atarisy2.c, badlands.c, cyberbal.c, galpani2.c, galpanic.c, gauntlet.c, klax.c, skullxbo.c, toobin.c and vindictr.c).
  . Disabled Clang warning for now (makefile)
  . Fixed compile (emu\dislot.c)
  . Fixed uninitialized variable, member or memory in cosmac\cosmac.c, cpu\lr35902\lr35902.c, cpu\mcs96\i8x9x.c, cpu\psx\psx.c, cpu\psx\rcnt.c, cpu\psx\siodev.c, cpu\sm8500\sm8500.c, cpu\tms9900\tms9900.c, cpu\tms9900\tms9995.c, cpu\v30mz\v30mz.c, diserial.c, hd61700\hd61700.c, imagedev\cassette.c, imagedev\floppy.c, machine\6522via.c, machine\6532riot.c, machine\6821pia.c, machine\6840ptm.c, machine\6850acia.c, machine\74145.c, machine\8237dma.c, machine\adc0808.c, machine\am9517a.c, machine\at45dbxx.c, machine\cdp1871.c, machine\i2cmem.c, machine\i8155.c, machine\i8214.c, machine\i8251.c, machine\i8255.c, machine\im6402.c, machine\mc68901.c, machine\mccs1850.c, machine\mm74c922.c, machine\mos6526.c, machine\msm58321.c, machine\n68681.c, machine\nmc9306.c, machine\pc_kbdc.c, machine\psxcd.c, machine\rp5c01.c, machine\tms9902.c, machine\upd1990a.c, machine\upd765.c, machine\v3021.c, machine\wd_fdc.c, machine\z80dma.c, machine\z80sti.c, sound\cdp1869.c, sound\ics2115.c, sound\mos6560.c, sound\mos7360.c, sound\pokey.c, sound\spu.c, sound\spureverb.c, video\cdp1861.c, video\crt9007.c, video\crtc_ega.c, video\ef9340_1.c, video\hd61830.c, video\huc6260.c, video\huc6261.c, video\huc6270.c, video\i8275x.c, video\isa_cga.c, video\mc6845.c, video\n64.h, video\saa5050.c and video\tia.c
- Debugger
  . Fixed crash with -debug when image loading failed (debug\debugcpu.c). Fill allocated memory with 0xDD pattern to make it easier to spot uninitialized memory in a debug build (emu\emualloc.c).
  . Fixed debug build (drivers\igs017.c, drivers\mediagx.c and video\taito_h.c)
  . Added a new 'lastinstructioncycles' property to the debugger to measure the amount of CPU cycles taken by the last instruction. This is useful to people who are rewriting CPU cores, specifically with regression testing (debug\debugcpu.c).
  . Added the ability to tracelog to '{game}' (without the quotes); performing a substitution when the trace is run (debug\debugcmd.c)
  . All cpu cores with a CPU_DISASSMBLE are supported by unidasm. Meant to sort these into cpu name order before last commit, they appear to have mostly been in "find in files" order before with manual changes (tools\unidasm.c).
  . UNIDASM
    . Fixed UNIDASM, but this fix is really gross. If we are serious about unidasm, somebody should figure out our strategy for ensuring that disassemblers are usable by this tool in a way that won't cause problems for device modernization.
    . Added TMS9900, TMS9980 & TMS9995 to UNIDASM. Other TMS99xx cpu cores are generated with macros, including the CPU_DISASSEMBLE.
    . Made 6309 compatible with UNIDASM
    . TMS57002 works in UNIDASM, disassemble interface can be revisited when all cpu cores have been converted.
  . Added support for Debugger registerpoints
  . Added 'exit' as a synonym for 'quit'
