Oh yes I know, I emulated GameCube and Wii for years, but I only have a laptop that while quite powerful heats up a lot while emulating, so since I need it for work I prefer to keep it cool and playing on the original systems allows me to do that :D also like this I don’t have compatibility problems, especially for x360 and PS3!
One thing that I don’t understand is: if they have a day one patch ready, why leave it as a patch and not directly integrate it in the game before launch?
