Is it possible to develop an app that runs Namco System 11 ROMs onto a PS1?

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 ...

Re: [Hardware Mod] NTSC/PAL reference oscillator mod for PU-

I have a question about this. I noticed that when playing my Japanese copy of Gran Turismo 2 on my PAL console, the opening movie will have an audio-video desyncing that increases with time (no desyncing at first, but very noticeable desyncing after a while). Will just getting an RGB cable fix this...
