@Psionic Roshambo, CPS II machines were also difficult due to the suicide battery keeping the chips alive containing the decryption keys to decrypt the game. And if the battery died, then the game won't boot.
Honestly with the library of the PS3 and Wii.... For me the Wii wins that gen. I like FPS more on PC so that just kills the PS3 library... Wii had more odd games.
