well in another thread I talked about gamesave exploits and I decided to attempt the project myself. Getting a buffer overflow shouldn't be that hard but... you need to decrypt and re-encrypt the file or else I will have no idea what I'm working with and it will tell me the file is corrupted if I try to modify it.
basically I need to create the overflow by making the name of my character or whatever about 20 more characters than your supposed to be able to have, creating the overflow and then find the offset and write some cheap-o assembly code to put there and it should launch. by cheap-o I mean I have no assembly knowledge so It would just be a little peice of code I find on the internet somewere.
I kind of wonder if converting it to action replay format will decrypt it. I'll look into that. anyways My sd Gecko is in the mail but might not arrive for another two weeks or so :mad: *Man I hate getting stuff from hong kong based sites.*
edit: md5 anyone?
update: via the use of emulator (yes I own a legit copy of ssb) I found that modifying both gci and gcs files, just the dates and not overwriting anything, they both say that they are corrupted files.
