Topic created on: August 18, 2011 09:47 CDT by wideout5 .

I'm a newb to the disassembling aspect of modding, & I was hoping I could pick up a couple things from here. After glancing through some threads I'm positive you are way beyond the level of what I am asking. Nonetheless, my goal is to take locate values I wish to change within an iPhone game, whether it be the exe or game saves. I've messed around with it a lot and have some idea, I am just not sure which values to change or what to change them to. I'm not looking for a handout by any means, but If anyone would be willing to let me send them the ipa or post a DL link & have a look I would very much appreciate it. The Game is Baseball Superstars II Pro v1.2 & I'm looking to mod values such as G-points, attributes etc. I haven't been in many forums so I hope I am not breaking any rules. Thanks

you should take a few (or more) saves, with as little difference as possible, and binary compare their contents.

for example take one save when your at pos X and another after you moved a bit and if the game isnt highly secure (has encryption or scrammbling) you'll see the field that describes the position. do a few of those and youll get most of the important values..

Thank you, I've tried that, but have too many variables. I'll try again though but maybe with a couple more attempts to narrow it down. I think the game may be encrypted or scrambled though. Anyone curious i can post the link for the file or email. This has been killing me not getting this.

Can someone PLEASE help me? I'm stuck at a point where i'm searching for strings and they are obviously all encrypted. I don't know if I need to run a debugger or if I can decrypt, or possibly even remove the file that instructs a decryption. I'm only trying to learn, if nothing else someone please impress me by showing me it can be done.. PLEASE.
