That looks great. I'm joining this club, because I've also disassembled the Game Genie.
But mine is not much to look at, it was only cleaned up enough to assemble, and raw otherwise.
There's an interesting situation with the Game Genie ROM. I can't find the evidence to back this up, but I could swear I remember someone on the NESdev email list contacted the president of Galoob, who agreed to release the ROM as public domain. This would have been the mid-late 90s. It's just kind of annoying that I remember that happening, but can't find a first-hand account of it. After that, I remember some emulators were distributed with the GG ROM. Not that legality really matters much with these old disassemblies, but it would be neat if there was public domain anything for NES.
If you don't mind, sometime I might start my project over with your disassembly. I had some bugfixes and one added feature which wasn't complete.
-fixes bad $0D color
-fixes audio bug
-fixes intro skipping (launch cart when start button is released)
-adds bootloader, based on blargg's code
