You don't really have the choice,you need the disc to play the game,you can't use roms for a PSX emu,you would need too much RAM.
The point of using an emu is because it greatly enhances the graphics,try to play GT2 and see the results.
many people who use emulators dont have a playstation. i myself bought several psx games when i got my bleem! cd.
and many others play on their pc because of the improved graphics and gameplay. so dont ask for games or sites. if you want to try a game before buying it, rent it.
> whats the point in using your PC if you already have a
Maybe it's because they want a vast improvement in graphics or having unlimited memory cards at their disposal (yeah, I know there are ways around that without using an emulator, but I don't care for them).
I don't like the way this thread is going, so I'm going to lock it. Read the forum rules. Bah, Bgnome beat me to it.
