MAME 0.254
MAME 0.254, the most hotly anticipated emulator release in recent memory, is ready today! Yes, it finally happened: the first batch of Namco System 10 games have been emulated! It’s been a real team effort, with contributors around the world working on emulation, cracking encryption, and properly dumping the Flash memory chips. You’ll be able to enjoy Namco’s Mr. Driller 2 and Mr. Driller G, as well as the spin-off Star Trigon. System 10 was home to Mitchell’s final two arcade games, Gamshara and Kono e Tako. From Metro, there are two GAHAHA Ippatsudou mini-game collections and the two-in-one mahjong tile puzzle game GekiToride-Jong Space. Other working Namco games include Kotoba no Puzzle Mojipittan, Panikuru Panekuru, and Uchuu Daisakusen: Chocovader Contactee.
Quite a few of the System 10 games that are still marked as not working are already playable. Taiko no Tatsujin 2, 4 and 6 are playable, although we aren’t confident enough in the timing accuracy of MAME’s PlayStation emulation to mark rhythm games as working at the moment. You can play the light gun shooter Golgo 13: Juusei no Requiem, but it’s missing sounds and voice acting at the moment. Several coin pushers on the closely related WIDEISM SP-02 platform run; you can trigger various animations, but there’s no gameplay as such.
Of course, Namco System 10 emulation isn’t the only thing that’s updated in this release. Almost a dozen Yamaha keyboards based on the GEW7 CPU are now working. Interestingly, their sound synthesis capabilities are closely related to the MultiPCM chip used in various Sega arcade games. Another game from SNK’s early Micon Kit series has been dumped and emulated. There are also two more working Brother word processors and two working Liberty Electronics serial terminals.
Cave CV1000 games now have more realistic blitter performance, meaning you don’t need to tweak settings to get close to the arcade experience. Properly emulating the absence of a memory management unit in the R4650 CPU used by Namco’s System 23 solves crashes in Time Crisis 2. Some fixes in SGI workstation emulation have IRIX running again. A few bugs affecting PC Engine and Virtual Boy games have been fixed. Issues with certain sound effects in classic Konami arcade games have been fixed, too.
That’s all we’ve got time to talk about here, but you can read about all the work that made it into this month’s release in the whatsnew.txt file. The source code and 64-bit Windows binary packages are available from the download page.

It’s the challenge.
Can’t settle for bootleg Conic Football while Mattel Electronics Football had not yet been emulated. And nice to have both games emulated.
I hope DX7 does get fully emulated since it was an iconic version back in its days.

I have a Yamaha EX5 that I bought fifteen or so years ago that turned out to be simultaneously too big for me to transport and not powerful enough to do what I really wanted. If a dump is needed for emulation purposes, I can try to dig it out of my storage unit, but it will be a while before that can happen. I also don't know how I'd manage to ship it to a dumper.

Those VSTs are simulation, not emulation (at least all the ones I have seen). They try to re-create the sound of the DX7 rather than actually emulating the main CPU, sub CPU, YM2128, YM2129 and other chips.

This is only partially true. There are VSTs out there, that do emulation too. Reaktor (NI) for example or some of the Arturia, Korg and Roland ones. Some of them are so good emulated, that they are able to load original patches from hardware, i.e. Wavestation, alpha Juno etc.
I like the Synths that MAME have, but they have a to big delay when it comes to MIDI connection and integration in a real world hardware setup. Still nice to see them and i guess that especially the Yamaha stuff will come in handy, if emulating other stuff in the arcade world.
However it does not help to "normalize" the prices of real world hardware. Some of them are simply hilarious out of scope.

Bob Zed: What’s new in MAME 0.254

MAME 254 - What's new video clip.
The neat feature segment is the fixed bugs portion of the video clip showing side by side before and after windows of what the bug effect looks like and next to that is the bugs fixed after window showing the bug fixed results of how the game should actually play. Haze has done that style in the past on occasions, but it is a useful feature.
I liked Darkmoe’s old videoclips presentations in showing emulation of some handheld game and in the corner is a photo of the actual product that is being emulated. Good to see Zed’s video clips doing something similar, but in a different style. A useful feature for those that might have never seen actual handheld toy product in person.

It was back around either 2013 or 2014 I visited a music forum
and one of the threads had a discussion about which were one of the better products to purchase.
One of the posters had recommended a product that he believed the keyboards were emulated, but maybe on High Level Emulation ( HLE ) rather than low level. I should have saved the url and website at the time, but never got around to doing that.

At least come in handy for repair techs if needing to replace any specific rom in order to get a keyboard back into working shape in case a rom goes sour.
I am glad the Casio RZ1 is almost completely emulated. I hope a couple of the Roland early 1980s drum machines get emulated sometime later.
The ultimate would be if Synthaxe could ever be emulated. That would be almost the tops imo.

Not that I'm finding. Any emulation would obviously be welcomed but I wouldn't trust any of the music ROMS that are being added at this point. I keep coming across incorrect ROMS for various bits of hardware. I tried getting involved to get them corrected but nobody seems to care. When a hacked ROM is noted as the only official OS ROM (vs twelve different official OS ROM revs) and a hobbyist's sound roms are the ONLY sound roms listed for the synth, it's a problem.

Absolutely agree, plus any ROM cards are sooo insanely expensive. I mean seriously, there are some, you could buy a new decent synth for it. I wonder if there will ever come a point, for some realistic prices. I guess never.

The EX5 was released 25 years ago, isn't that exactly your favorite "period of personal interest to constantly reminiscence about" (besides the 1970s)? But i'll give you a hint:
Code:
All is exciting and fantastic until one reads the polyphony spec:
Voice Type EX5/5R Polyphony EX7 Polyphony
-------------- ---------------- -------------
AWM/Drum 126 64
VL+AWM 1+AWM
FDSP 16 8
AN(Poly)+AWM 2+AWM 1+AWM
AN(Layer)+AWM 1+AWM
AN+FDSP AN:1; FDSP:8
So, I would forget about that fat stack of AN or VL oscillators (layers). Forget phat two-handed analog chords.

Why are you not reporting the bad ROMs to the MAME devs and have you talked to them

Dont want to sound like a asshole here, but it would be nice to know, how you would do that. I mean sending you ROMs or ROM cards, basically means the hardware becomes useless.
How long would that be in your hands, until you send them back?
Even more interesting, how can you dump ROM cards?
I ask, because noone did it before, at least i never heard of anyone. Just curious here.

I personally don't do dumps. I have neither the hardware nor the know-how. But from my reading McHale does, or otherwise we can see how to put him/her/it in contact with someone who is competent about it.

I *USED* to do dumps, quite a bit. I've been repairing/modding synths for decades. I have the FW ROMS and service manuals for many MANY synths and pieces of music gear.
For example, I was doing DW-8000 ROM dumps of my own gear back in 2010 - https://www.harmonycentral.com/forums/topic/145678-for-all-korg-dw-8000-owners/
As a sidenote, as of 2010, Ver 12 was the last official FW Korg released for the DW-8000. My copy came directly from Korg USA. The ver 13 that is out in the wild right now (and included in the DW-8000 MAME ROMS) is probably unofficial. I'm trying to verify right now.
Here's the hack I did on the Korg M3 in 2009 - http://karma-lab.wikidot.com/korg-m3:expanding-the-internal-sd-card-to-2-gbyte
I also have the full waverom data for the Triton in a file once someone is ready for it.

You can get a bit-accurate DX7 VST that uses actual emulation from friends-of-MAME Plogue. Works with original SysEx dumps, and you can choose which model DX7 to match the different output stages.

I'd like to see this compared to DEXED, which is free and also imports original sysex dumps. I've been using it live for a few years now and it's given every DX-7 VST a run for it's money so far and is basically the gold standard for DX-7 softsynths.

It compares extremely favorably, given that it's bit-accurate (meaning the exact same samples come out of the FM chips as when you put a logic analyzer on the hardware). None of the big-name VSTs like FM-8 attempt that.

I don't think we have anything on the Triton. Looking at the schematics, that system seems to have a bunch of roms:
- internal and external flash for the main cpu, a sh2 (the upgrade packages seem to have the full internal flash (yay!) and 3/4th of the external flash)
- wave roms for the master synth chip
- internal flash/rom for the keyboard control cpu, a h8/3337
- internal flash/rom for the main cpu of exb-moss board, a h8s2655
Do you only have the wave roms or also some of the rest?

Are the MAME Yamaha FM cores (OPL2/3, YM2151 etc) bit-accurate to the real thing? (is that even a goal for the MAME project?)

> Do you only have the wave roms or also some of the rest?
Just the wave roms. I have a fully loaded Triton Pro here (with EXB-MOSS and EXB-SCSI) but I still gig with it so couldn't afford to tear it down to unsolder and read the roms.

The current YMFM cores are very accurate (on par with the Nukey cores) but not bit-accurate (or at least not tested to be). That wasn't Aaron's goal.

Is there a MAMETesters issue on this, ideally with a real PCB recording for proof?
ETA: there is, for one specific sound effect that plays on the title screen. If that's what you meant, great.
