I seem to recall someone explaining to me that ROMhacking does not involve accessing the original source code at all, only the form the code takes in hexadecimal
You've been a member of this site since 2007, and only NOW you realise that we don't hack with source code? I mean... huh?
If we had source code, it wouldn't really be hacking, would it? It would be making a branch or a fork or an alternate version or something.
Anyway, I don't know about mobile games. I just wanted to comment because you surprised me.
EDIT: don't get me wrong, I'm not trying to criticise you. I just thought that since you've been around this fine group of people for a while, you might try to do some hacking yourself, instead of paying others to do it?
If you can figure out how to access the graphical elements inside an APK or whatever (assuming it's an Android game), you might have a chance, but given that I've never even heard of anyone trying to hack a modern phone game, I would say your chances are slim.
