* "Match Wii Game" controls option! Games that have a Wii equivalent can be played using the controls for that Wii game. For example all Zelda games can be played with Twilight Princess controls. See the Instructions section below for important details. * Rotation/Tilt sensor games all work * Solar sensors (Boktai 1/2/3) * Rumble (except for games that rely on Gameboy Player) * Keyboard * PAL support, finally! * New scaling options, choose how much stretching you want * Colourised games now partially work but still have distortion * "Corvette" no longer has a screwed up palette (but still crashes) * Triggers net reconnection on SMB failure * Source code refactored, and project file added * Instructions section added to this readme file
