I don't think there is a PS3 version, but I can load it on my PS3 with CFW, but I don't have a true backwards compatible one. Is that valid? Are all consoles valid for the same scores? Often HD and SD are seperate because different engines and load times / frame rates. The 360 version has much different menus than the PS2 version and probably many other differences, but I'll have to play more to see for sure. Is there a preferred difficulty? The rules don't specify, so if not then I'm going with Easy. Is PS2 OPL valid? (Faster load times). That's it for now.

Sorry lot of questions. For now I'm just going to run 360 version on Easy, I won't bother with PS2/PS3 since the 360 version likely has superior performance.
