Search the web for epsxe (or around these forums wink wink)
and install it.
IF you use the software based video plugin and no sound, can you run the epsxe emulator on the PS3 under linux (linux version of epsxe I guess)?
Could someone try this out? I know I've heard people getting Snes9x to work on the PS3, and this is only a step after that right?
