okay, anyone here who owns an XBOX 360 probably knows of the programs modio, 360revolution, or horizon. what i am wondering is, how would i make ONE save editor for a game like forza, just for moddiing credits (intergers) in the gamesave?
Your best bet is to google it. I have no idea how to even begin to edit a 360 save file. More so, I don't believe anyone is about to help you mod/hack a save file. Play the game and earn what you want.
I dont really play XBOX 360 games so I cant really give you a specific solution. I would say that you make a save and then do something in the game to modifty the value(s) you want to target, then save it again and compare the two save files in a hex editor. Then you look for a large region of bytes that are diffrent. This regon would probably be the part of the save file you are looking for. Then you have to figure out how the game uses the data in that region to do whatever it is that you want to change, and then you have to write a program that changes it depending on the users input. Or if the save file has comments regarding sections of the data and what there used for then you could have look for them. Although something like the game credits may be literal and not editable without a decompiler and whole lot of fuss
