Endless Paradigm

SRB2Wii is an unofficial port of the 3D platformer fangame Sonic Robo Blast 2 to the Wii. The PowerPC Linux version of SRB2 runs under a tiny Wii Linux distribution loaded from an image. SRB2Wii is under ongoing development.

CHANGELOG
=========
Features and bugfixes: - Booting SRB2Wii from a USB stick is now fully supported, although it most definitely will be much slower than doing everything under the internal SD card slot. - The GameCube controller is now fully supported. - Multiplayer support has been coded in, although due to limitations with wminput, only one Wii Remote can be connected at a time (more than one GameCube controller can be used however), and SRB2 seems to be having problems with registering input from the second controller ingame. This will be fixed before the stable release. - The extended swap is now supported again, and it really does make a difference with larger levels. Under the Settings menu of the launcher, you can tell the SRB2Wii system to create the extended swap file (which will then be used by default from then on). Be warned that this process will take a little while and requires some disk space, as the extended swap file is 128MB.

Regressions and bugs: - SRB2Wii/mini will not load anymore, so not uploaded this time. - Fine text on the splash screen isn't rendered properly. This will be fixed in the future.

Future features: - Internal updates through the Internet.

Yep, wee are getting there! To the final version of SRB2Wii v2.0.0. Hopefully, SRB2Wii can be made to be as functional as possible, and to have great SRB2 performance as well.

I might look into this, I loved the PC version.
