From readme:

* "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.
* 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
