So first off I'm a tiny bit inebriated as I write this, so pardon me for bringing this up as an idea as odd as it may sound. I remember a while back while trying (and failing) at making a ROM hack (probably when I tried (and failed) to translate MapleStory DS) that you can take the source file and the output file and make a patch containing the difference between the two files. If I remember correctly it was with xDelta but it may have been something else. Since we're anti-warez distribution here, I became curious if the possibility to secretly distribute a game as a patch exists? (not that I want to!) The idea is that you provide the patch maker with a source ROM (gameA) and the output file is a different ROM (gameB). Seeing the difference between the files, a patch containing all of the data for gameB is created. From here, the idea is to patch gameA with the patch containing all of the data for gameB, and gameA then is entirely patched into gameB, all the while looking like an innocent (and oddly large) patch file. Is this theoretically feasible or am I drunkenly overlooking something? Not that we get too a huge amount of fan patches here, but if it's possible it is technically something that -could- happen here.
