Capcom's ZN-1/2, Namco's System 11/12, Taito's FX-1A/B and Gnet Support Inquiry.

[Ntemis]

I have been wondering how much of a challenge it would be to modify this core to support said cores.

Capcom ZN-1 - Uses the same CPU, uses Capcom Q Sound, and uses the z80 to control sound. Pretty much all of this ought to be possible. The hardest part would arguably be the ROM loading. However the largest roms for it were 32Mbit so that shouldn't be too bad. however, the extra soundboard for NBA Jam Extreme might complicate things.

Capcom ZN-2 - This was actually a higher performance version of the ZN-1 CPU.

Namco System 11 - Custom sound chip and cpu

Namco System 12 - Same processor as the ZN-2 most likely, slightly upgraded PSX CPU for higher bandwidth. It also has a different sound chip than the system 11 and the others, in addition to one of the sound chips from the system 11.

Taito FX-1A - Uses the higher end 48MHz CPU like the System 12 and uses a ym2610B and z80 for sound, in addition to the PSX SPU.

Taito FX-1B - Same higher end 48MHz cpu as the last one, yet another new sound cpu, and uses two dsp's for the sound chips in addition to the psx SPU.

Taito G-NET - This one used compact flash cards other than this hw looks identical
