PlayStation Development Network

I know, this may be a weird question. Of course it's impossible to run Namco System 12 games on retail PS1 hardware since that arcade system has a higher CPU clock frequency, but I was wondering if it was even theoretically possible to create some sort of emulator for the PS1 that runs Namco System 11 ROMs. The CPU and GPU are exactly the same, but the SPU is different, which may make it impossible, not to mention that having to switch from solid-state ROMS to CD-ROM could cause issues as well.

What prompted me to ask this is that the Nintendont homebrew application for the Wii allows for Triforce playback.

It also has double VRAM. Anyway, in theory, yes, anything like this is possible but the system would need a lot of modifications since the System 12 is a custom board.

I see. Thanks for the reply.
