Erm... we CAN change the game's programming. Is the thing.
True. But I don't think it's been figured out too well, because if we did have easy access to changing the game's programming, we could finally add new content and go beyond file patching.
We could also program the game to go back to the previous menu if it tries to load more than 90mb into the ram :O
Also to expand off the riivolution thing, if you have RiiFS set up, it tells you when each file is loaded. Pretty cool. Haven't tried riivolution with Brawl yet though, so far I've been hacking Fire Emblem Radiant Dawn. My brawl disc is coming in today so I'll fool around with that.
