Wow. This is fifteen kinds of amazing and I want it.
I do have a question, though. Because -- and please understand that I am a moron -- I have no idea how this magical HANS system works, I have to ask: does this hack alter the cartridge itself, or does it just use the cartridge as a base and you have to load the hack through HANS every time you play, leaving the cartridge itself untouched? I swear I asked Google, but nothing was very clear and I feel much better asking the question flat-out before I do something potentially irreversible. (This is probably the dumbest question anyone has asked in this entire thread.)
