What is the best program to use. I use le fluffie , but it not working right on one game i modded before. Now the game keeps loading. I put it back to standard and fixed it with le fluffie but it keeps doing the loading screen... and never loads the game. Im not using gamesave, but modding files in the games.
If you have the sdk you can use the xbox 360 and live authoring submission tool to recreate the xbla package, you will also need yaris swap to patch the file. (thanks to begal for this info)
