eboots are nice, how hard would it be to implement a converter to take PSX isos and rip the Wavs and FMV and encode them with Vorbis/Theora and have the emulator play those files accordingly?
Very very mega-hard to impossible since the emulation actually works at a lower level than "play this audio or video file", sorry. It's more like "decode this block of data into video" and then someplace else completely different "output this image to screen" which is all controlled by the game that's running. Patching that would require understanding the works of the games which is a bit too much IMO.
