Thanks for the warm welcome! I have tinkered with my purchases in Virtual Console as well, that's what gave me the idea! I cant imagine them reworking the entire game, if they wanted to retain its originality. I have posted this on other sites and havent heard anything, so either there isn't much interest on the Xbox scene, or I just havent seen any substantial articles on this yet. Out of curiosity, I looked into the PS3 version of the game as well, and found the structure, and the file naming, and size to be identical. Basically, they are the same files, just packaged to work with the PSN. From what I see, I can guess is that this Simpsons.sr file contains the US as well as the Japan ROM.
