As I see some initative and people asking what's next, here goes some Info.
Only the 1st two will happen for sure, the rest to be decide.
1) NeoGeo AES Multi
2) Bug fixing of deco multi
New cps3 bios?
Cps1?
Pgm?
System16/18/32?
Right now, I dont see a Naomi or model2/3 multi happening tbh.
I see coming some other nice multis from other users like for irem92, system 246/256 and kaneko, so keep an eye on the right section...
Out of interest, why the new CPS3 BIOS? The current one seems to work fine
I think the market is definitely there for a CPS1 multi, but I think the A custom needs to be reproduced to ensure long term reliability
System 16 I'd be all over, I've been doing some basic research into how the different ROM boards operate and I'd be happy with a universal ROM board if for whatever reason a multi wasn't possible
