Ok, I've searched sources I must said it is damn good piece of code. This revision r2 is different than know Zelda's version because I found some interesting addons that "probably" Crediar tested another games and probably after compiling code games like Pokemon Chanel, Kirby Air Ride, Chibi-Robo, Super Smash Bros Melee, Mario Kart, Double Dash, Mario Sunshine. This is simple examination of this source
https://code.google.com/p/nintendont/source/browse/trunk/kernel/Patch.c
I do not know it for sure, but probably also for now only FAT32 will be supported.
Probably we have also get fist compiled version because some sources was updated 60 min ago so - I am happy to test it when it will be ready
