hi, thanks! I'm the author. I stripped out some of the things from the blog post that I tried that lead me down the wrong path, so while it reads like I kept making progress.. I left out the 3 or 4 things I'd try without any results. I have done a bit of work in the past reverse engineering: - I figured out the SHA-1 encoding mechanism on xbox 360 .XEX files - I modified a laptop's BIOS loading bitmap image (that originally said 'toshiba') - http://os-fun.blogspot.com/ http://os-fun.blogspot.com/ - A friend and I extracted the level data for the game "skyroads". We couldn't figure out the file's compression format so we ran the game in DOSBox, and dumped the entire 640k memory with GDB and then searched it for the decompressed levels, then ported them to some open source skyroads game.
