- CPU
. Analog Devices ADSP-2100: Code cleanup: Use BIT helpers for unpacking and disassembling opcodes. Use count_leading_zeros_32 for "detect exponent" operations rather than shift loops. Convert comments to C++ single line style and some constant macros to unscoped enums. Deobfuscate bit manipulation in the "mode control" instruction. Fixed more comments in disassembler (adsp2100\2100dasm.cpp). Fixed a couple of disassembly regressions (adsp2100\2100dasm.cpp). Fixed one operation (adsp2100\adsp2100.cpp).
. Hitachi SH-2: Refactored SH-2 refactored code to separate onboard peripherals from CPU core.

. Added hard-sector floppy support (imagedev\floppy.cpp)
. Added optional logging for data reads and writes (machine\wd_fdc.cpp)
. Recognized SSDD images for 3(.5)-inch floppy drives (formats\td0_dsk.cpp). Fixes loading of (MESS) CP/M Plus v1.5 on pcw8256. Do more error checking, hopefully eliminating softlocks when trying to load truncated images (formats\td0_dsk.cpp). Don't swallow bits and bytes at the end of Huffman-encoded images, when the word buffer can no longer be filled (formats\td0_dsk.cpp).

Moved read handler directly into the map segment and renamed hardware type device tag. Correct accidentally moved line break. Switched from native array usage to optional_ioport_array. Changed dsw setting order in UI from on-off to off-on.
- gei.cpp: Found documentation confirming Sex Triv is an alternate ROM question for Series 7. Verified undocumented Series 12 N.F.L. Football question ROM. Added Adult Sex 3* question ROM to Series 11, with documentation. Verified Newer Adult Sex 2* & Adult Sex 3* questions ROMs and labeled alt sets as "old".

- ojankohs.cpp: Fixed Chinese Casino [BET] (Japan) freezes when you select a girl and start the game. After the dice is rolled and the tiles are distributed and arranged, the game will not move beyond that point (ID 08756).
- pgm.cpp: Hard-code sprite zoom table entry 0x0f to 1 (igs\pgm_v.cpp). Note: Some games (e.g. DoDonPachi III) have zero in last zoom table entry but expect 1 is the last entry hard-coded to 1, or does zero have the same effect as 1?
- segaorun.cpp: Reverted erroneous change in MAME 0.258. Fixes Super Hang-On crashed after insert coin (ID 08769).
- segas18.cpp: Eliminated runtime port tag lookups. Use 8255 PPI for 4-player versions of D. D. Crew. Use MSM6253 ADC for gun inputs in Laser Ghost.

- speedatk.cpp: Fixed clock frequency of Z80 and AY-3-8910 based on video footage of real PCB (ID 08764) (see https://twitter.com/BEEP_SHOP/status/1385425741236432897)
- system1.cpp
. Do cycle adjust with modulo instead of float
. Changed Z80 CPU1 clock speed from 20MHz to 4MHz. Note: A 20MHz crystal clocks an LS161 which counts up from either 10 or 11 to 16 before carrying out and forcing a reload. The low bit of the reload value comes from the Z80's /M1 signal. When /M1 is low (an opcode is being fetched), the reload count is 10, which means the 20MHz clock is divided by 6. When /M1 is high, the reload count is 11, which means the clock is divided by 5. Since /M1 is low for 2 cycles during opcode fetch, this makes every opcode fetch take an extra 2 20MHz clocks, which is 0.4 cycles at 4MHz.
- vegas.cpp: Fixed shift count bug in 48-bit and 64-bit big-endian functions (util\multibyte.h). This fixes "CHD ERROR: Decompression error" in sf2049, sf2049se and nbagold (ID 08768).
- zac1b1120.cpp
. Fixed zoomed sprite mask. Fixes wrong graphics when cars crash in Dodgem (ID 08748)

Added support for the bidirectional stepper motors for cat arms. Hooked the arm sensors. Figured out and added the food lamps. Added a internal layout with all the output lines activity, besides a working playfield. Added technical notes. A lot of other things to get the game working. Use the external artwork for a realistic experience. Added a PCB layout. Improved the interrupts timming. Fixes some bits and matches the game duration and arms stress as seen in the videos floating around. Verified OKIM6295 pin7 high. Added partial PPI's connections and CPU clock from crystal diagrams.

- Track & Field: Re-dumped ROMs for clone Hipoly (bootleg of Hyper Olympic) - promoted game to working.
- Video Poker: Restored full NVRAM saving
- Unknown Cointek game: Possibly descrambled audio CPU ROM. TODO: Decryption may be incomplete, though code flow looks sane both for the main CPU and the audio CPU. The game puts some strings at 0xc000 and at 0xf810. At 0xf810 it puts 'MICRO' in DPRAM and then it expects to read 'DRAGON' (put in DPRAM by the audio CPU), if it doesn't it loops endlessly. For reasons to be investigated the audio CPU puts it at a slightly wrong offset. HD63310 seems to have more features than the DPRAM chips emulated in machine\mb8421.cpp. Maybe reason for the above problem?
