Despite RPCS3's developers claiming the program's minimum requirements have "no performance or stability guarantees", some of the PS3's games are quite emulatable with mid-end hardware.
to do: test Sonic the Fighters
The ICO and Shadow of the Colossus Collection - the game selection menu works, but the games do not
Jet Set Radio - runs perfectly
Ketsui: Kizuna Jigoku Tachi - runs fine
Nier Gestalt - plays fine, but graphics are foggy and audio is delayed
NiGHTS Into Dreams - updated graphics mode is slightly slow, but Sega Saturn Mode runs perfectly
Rayman 3 HD - audio is fine, but framerate is too low to be comfortably playable
Rayman Origins - graphics and framerate are fine, but audio is messed up. Consider playing the Windows version instead.
Sonic & Sega All-Stars Racing - nearly everything is white and playability is nonexistent
