I probably should have said my target is mvs, so I’m looking at m68k games with z80 sound. neither lover boy nor rtype fit that, so it won’t be either of those. But thanks for the suggestions! Maybe another neo cd…

I would love a port of Taito's Rastan. How doable would that be?
I would say “most doable of the suggestions so far”!

This 19YY port was like a 1/10 difficulty. So that’s also my skill and knowledge level on how to define “doable” here. I would guess Rastan is more like a 4/10 but again I’m still learning. m68k cpu, good. Z80 sound cpu good. Different Yamaha audio chip but I think it’s similar enough. there are some custom video chips on that pcb, not sure if they do anything the neo hardware can’t. Some of the memory map regions seem like they overlap but plenty need remapping. Otherwise I think reworking the graphics and graphics code would be the hardest part, but that’s probably a standard challenge for anything outside of neoCD.

Anyway, good suggestion! I still gotta work my way up to 4/10 though. I have a 2/10 in mind so I’ll see how I do on that first.

I’m sure some heavy hitters are on here so if they see this and want to chime in with a better answer, go for it.

Heh, that's pretty cool.

Any chance you could port some games the other way? I'd have thought Zupapa! would work nicely on the NGCD :)

Even tho I already have em on pcbs, Final Fight or Sunset Riders would be ace.

Ok well thx for the suggestions. I’m gonna take a non-neo detour for a short bit but hopefully I’ll be back with another port afterwards!
