Pepone has made an new beta version of his great neogeo emulator. The new version support sound processor (Z80+YM2610) on the second gp2x processor (ARM940t). Now most of neogeo game work full speed with the gp2x at 200MHz and sound on 22050Hz. Some game not work with sound (wind jamer, street hoops, Stakes Winner...) and sometime when there is lot of frameskip (for game that need a gfx dump, when the sd card is accessed), the sound can skip a lot.

The speed sucks unless ram timing tunning are enabled.
To enable it, just put this in your conf/gngeorc file:

CODE

ramhack true

Thanks Notaz for all his work on PicoDrive who has showned the path to second core use.

New beta here: http://m.peponas.fre...o0.7a-beta5.zip

Wow awesome!

Just when I thought the project was dead, a great update comes out

Can't wait to test later after work, thanks Pepone for the great work.

hahahhaha im so happy i could cry

[xnopasaranx]

cool! that probably means I can finally play "garou: motw" fullspeed with a little overclock.

I just got some weird behavior right now, and may have found a possible bug. So don't worry if it don't work out of the box, it's beta

pepone, I know that you might have been asked for this a zillion times before, but would you please (please please please) add support for two USB game pads?
Thank you sooooo much

SWEET!

What was your PayPal adress again?

[Rivroner]

No sound for me now
I have tried with Rage2x (i have enabled the sound with select and then pressing A) and without Rage2x

With Metal Slug 1 ( i have tested this one the most of time) i have random hangs.

[Julius]

Yeah no sound here either, but the second core seems to run as it freezes on anything above 250Mhz as all programms that use the second cpu do on my GP2x.

[jimid2]

Well, I just tried three games with mixed results. They all ran really well at 200Mhz, but none of them had full sound. In fact, I didn't even get the 8-note Neo Geo "330 Mega" screen opening motif for any of them. There were partial sound effects in each case, but they were incomplete, and no music. The games were Garoux Mark of the Wolves, Art of Fighting and Metal Slug. I'm running 2.1.0 on a mark 2 GP2X... I guess it's back to 0.7beta2 for me for now, but the speed was nice though!

[slaanesh]

I tried one game Art of Fighting 3 (AOF3).
Sound works fine... well for a while.. and then it starts to grumble and echo and get choppy.
Bur for the first 4-5 fights it's awesome.
Clocking at 200Mhz it's 60FPS until you start fighting, then it drops considerably. It jumped from 3FPs to 60FPS. Seemed like there was some massive variation.
Clocked at 220Mhz I was getting much better and more consistent results - 30FPS or so on average but getting to 50FPS+ as well.

It's looking really promising!

Great! Dare I hope that this version supports KOF2000 without graphical glitches?
