Very good and promising!How is the speed on a real Saturn?What is the level of emulation (sound, sprite priority, etc..)?
Actually it runs at 45fps on 50hz saturn.

I'm not sure sprite priority is emulated but colors, layers, sprites, scrolling are emulated.

But there is no sound and I've disable the second z80. The next step is to debug Raze with the help of SatCom.

OK, thanks.I'm asking this because sprite priorities are very important in Sega System 1 games, also MAME had some troubles with it in the past.Try Pitfall II, for example, to rest if they are OK.

Great work vbt !


Those Pang / Super Pang shots are gorgeous ...

Personally I'd love to see the M62 driver running.

What's the story behind cancelled drivers ?

ok, it will be the next one. I'll have to upgrade the menu to support a bigger list.

about irem drivers i got some problems with palettes(i think it's 32 colors palettes) and also a strange background layer. Vigilante is running.

About Black tiger, i was just lazy, i've ported most of the driver but didn't try it at all.

Nice! It just keeps getting better.
I'm working on a release version even if it's not perfect. I have a random bug I can't explain on Bank Panic.

When you kill a guy who delivers money you loose and then there is a problem on tiles, it's like it start column 2 instead of 0

Gardia is working better now, I've rotated tiles, map, sprites and fixed scrolling.

FBA is not yet ready for a release, I have some trouble to reinit things when you exit a driver. I it's not memory problems, sometimes it remains sprites (but i have erased all) or i get black screen but the menu works, i don't manage to reinit vram,sprites,layers everytime, it depends on drivers i quit.

Wow, my hat's off to you, man. That you have stuck with it and added all this stuff... and as for the stuff you're asking whether or not to add, I say go for it!


Even if it turns out a bit slow, you can't really know beforehand, so sometimes you just have to try it to see.
