Dude! You should really learn to use . and , when writing. It's really difficult to understand otherwise
Anyway, how a game loads its data is entirely up to the author/coder and the technical limitations of that game and thus varies from game to game. Many games even have their own fast loader / copy protection systems so that data is read directly from the disk tracks instead of files. Although many of these games were repacked when cracked for easy distribution it still depends on how the packing was done. So there's no way to make a generic tool, but one have to modify / patch every single game to be MMC64 compatible (as with, for instance, IDE64).
