I'm not 100% sure, but System18 and System32 should use the same PCM sound chip (Ricoh RF5c68, an 8 voices stereo PCM chip). The only difference should be the operating frequency, 10 MHz for the System18 and 12,5 MHz for the System32.

I think that's the "basic" earlier games. Out Runners, etc. use the multipcm, which IIRC is used also by Model 1.

As you wrote, the "System32 v2" (System Multi 32) uses a most advanced custom PCM chip (moreover the main CPU is a 20 MHz NEC V70 instead of a 16 MHz NEC V60) :)

If you were to port that (Namely the V60/70 cpu, I'd love to do SSV. :)
I will give it a try  :smilie:

Great... it'll give the opportunity to emulate the SEGA System 32 and Jaleco Mega System 32 games! Thanks! :)

SEGA System 32 is awesome (Arabian Fight, Golden Axe: The Revenge of Death Adder, Spider-Man, etc). Having it on FBA would certainly be great! :D

Amazing! ;)

PS: maybe I missed some steps! But is the NEC V60/70 core already ported by Romhack?

By the way, i was wondering, if you added multi-thread in fba (if i understood well, you'll need that for sh-3 ?), it would impact all existing cpus, or a rewrite would be needed ? (I've speed issues in "spectral vs generation" and "the killing blade plus" on raspberry, which is kinda sad because 3 cores are unused, so i was wondering if it could be the solution, since i lack the skills to port cyclone to fba)

Thanks a lot! The SSV hardware has got some very nice games! :)

Out of curiosity: does the ES5506 core require an implementation or is it already supported?
