ExileLord demonstrates how to reverse engineer and patch a bug in Guitar Hero III using a disassembler and decompiler.
Reverse engineering Guitar Hero III over the years has been a hobby of mine. This is a short journey into the process I go through trying to fix a bug in a game that I don't have the source code to. A lot of work went into this video. Please leave a comment if you have any questions. This is a very technical video so if you have zero experience with programming a lot of this will probably go over your head. I try to dumb down as many things in the video as I can but I can only do so much. I'll add an FAQ here eventually if I answer enough of the same questions in the comments. The fix for those that are still playing Guitar Hero III and don't want to make it themselves. Overwrite the existing file in your scripts folder. mediafire.com/file/es4s1cga1t56ycx/engine_params.qb.xen Shoutout to Megapeng for letting me use footage from his stream. His youtube page if you're curious: youtube.com/user/megapengproductionsWhy it's here
