They should, but doesn't the PS3 have to have a mod-chip beforehand? Or could games potentially be stored on the hard drive? :confused:
The PS2 needs a mod-chip, but a swap disc works fine so no actual modding is needed (except for changing the flip lid) - I play homebrew with a swap disc :D

Question for anybody to answer:
Is downloading (console) Demo Disc's illegal? I know that downloading full games is illegal, but Demo Disc's from (dead) consoles such as Dreamcast and PSone I don't think should be - or is it?
