Emu#dreams reports that Frank Palazzolo has been working on adding more hardware support to MAME, the Multiple Arcade Machine Emulator. Below is a post from his blog about some of the work he's been getting himself into.
Actual MAME-related work!For those who haven't heard, the speech chip used in Berzerk has been reverse-engineered by "Lord Nightmare"! This is something I've been waiting for for about 7-8 years! I'm sure that the emulation will end up in MAME and PinMAME sooner or later.
Because of this, I spent some time over Christmas looking at the analog filters on the Berzerk speech board. (These are applied to the sound after it comes out of the chip.) I finished the analysis, and it should be pretty straightforward to add them into MAME after the chip emulation is done.
For what it's worth, I've been trying out Maxima with wxMaxima to do the symbolic math for circuit analysis. I know, I could have used SPICE or something - but doing the math from scratch makes it easier to understand what is going on.
After I worked out about half of the math for these filters by hand, I ended up with about 6 pages of algebra. At this point, I figured I should use this as an excuse for learning Maxima. Sure enough, I found an error on page 5. Darned minus signs!
The second half of the analysis took about 5 minutes, since the code from the first half was already done, and I could re-use it!
For those who care - the filter is a third-order lowpass - a first order lowpass, followed by a second order with a resonant peak around 2400 Hz.

Emu#dreams reports that Haze has been working on MAME, the Multiple Arcade Machine Emulator, some more. Below is what he posted on his official MAME WIP page.
BackFire!Again based on Bryan’s work I’ve split BackFire! from the generic 156 driver and put it in it’s own file. The game is fairly different to the other Deco156 based games in that it supports 2 monitors. Both Monitors are now displayed, although colour problems remain. The game remains unplayable as it needs further work on the maths co-processor.

You need to state the emulator in the topic title, not the name of the game. It's not 1FinalFantasy, it's 1Emulation.

Emu#dreams reports that advances in support for World Cup Volleyball ‘95 in MAME, the Multiple Arcade Machine Emulator, have been made by Haze. Below is what Haze posted on his official MAME WIP homepage.
I decided to take a look at some more of the things Bryan submitted. I’m currently looking to hook up both screens in BackFire (it’s meant to be a 2 screen game) and seeing if I can make any progress with the Co-Processor.Dox found what appears to be a bug in the ARM core, a workaround allows World Cup Volleyball to boot, and a few fixes to the Co-Processor gets proper working credits and timers. The game is quite playable, although seems too easy, maybe due to other copro bugs.
DON’T expect this to be in the next u update, the workaround hasn’t been fully tested, nor have the copro changes but this should give you some idea of what it looks like.

Emu#dreams reports that Bryan McPhail has been working on fixing hardware support in MAME, the Multiple Arcade Machine Emulator. Below is his post from his MAME work-in-progress page.
There has been a long-standing known bug in dec0.c for some time (checking my notes, it's been there for 7 years!), in that row & column scroll could not be applied to a tilemap simultaneously. The reason for this limitation is that Mame's tilemap system did not support this. Anyway... I've re-implemented the rendering of this sytem by providing a new tilemap draw function that correctly implements simultaneous row & column scroll. I also verified the rendering of all video modes using a trojan on a Birdie Try board. This finally fixes the waterfalls in Midnight Resistance! (It doesn't really affect any other games, but the source code is much cleaner now).Whilst working on this driver I noticed there are several revisions of games that are still not dumped, eg, Japanese Heavy Barrel, World Fighting Fantasy, USA Boulderdash. If you have any games on this hardware please check the revision/rom-code ID against Mame to see if you have an unsupported set.

retroguru.com reports that SquidgeSNES, the brand new Super NES emulator for the GP2x, has been updated to version 0.0.2. Here's what Squidge, the programmer, had to say about it.
ok, I've just uploaded version 0.0.2:Now uses Rlyeh's SDK instead of my own
Only one file now instead of two
Double buffered instead of single buffered
Colors corrected
Controls implemented (game are now playable, yey
)I've just implemented an onscreen fps counter (will be available from the next version for anyone who cares) andi n SMW I get a fairly consistant 40fps. I reckon I can get this to at least 50 fps, if not 60 fps over the next few days. Stay tuned

YMP internally decompresses LZH-packed YM files (LHA.EXE is no longer required), and disabled channels don´t make any noise now. A tiny bug in the ZIP archive handler and another one in netplay (discovered by Shane) have been corrected, too.You can visit the official homepage here, or simply download it here.

iq_132 has reported that Haze has done some work on fixing hardware support added to MAME, the Multiple Arcade Machine Emulator, by Luca (posted earlier). Below is what Haze posted on his WIP page (truncated).
Twin Action vs. MustangSo.. it seems Afega’s games aren’t so original either… Luca recently added support for Twin Action, but it wasn’t working; it reset when you hit the fire button and the player sprite was invisible. That behavior reminded me a lot of a previous game I’d look at, US AAF Mustang, actually the whole game did right down to the parallax scrolling sprites for the ground. Sure enough comparing the Afega and NMK16 drivers revealed that Afega had copied most of the NMK hardware and that Twin Action was nothing but a bootleg of US AAF Mustang. By using the same protection patches as used for Mustang (with some slight adjustmenets to compensate for code being moved about), Twin Action started working.

Emu#dreams reports that Luca Elia has been working on adding support for more hardware in MAME, the Multiple Arcade Machine Emulator. Below is Luca's post about the work, originally riddled with screenshots (so, there are gaps).
I've added a 1994 arm wrestling game to the cischeat.c driver. It's Jaleco's Arm Champs II, a dedicated machine with a real mechanical arm to battle against:This kind of games are Jaleco's specialty (see the hilarious Scud Hammer) and not quite the same in MAME.
A prequel also exists, but it's a most wanted rom.
Then there's this game from korean Afega, that I've added as non working to the afega.c driver. Only the attract mode works, while playing you are invisible and off screen (last screenshot):
(Haze correctly points out this must be a bootleg of US AAF Mustang, which is also protected and not working).
Finally, a couple of Dynax mahjong games added to ddenlovr.c for good measure. They are Mahjong The Dai Chuuka Ken..
.. and Mahjong The Mysterious World:
