Riivolution is an on-the-fly game patcher for use with retail discs. It allows users to place content on their SD or USB devices, which will be read by the game during regular play.

It can be used for custom textures, music, levels, memory patches, game translations, and more!

Changes:

– This update provides behind-the-scenes fixes that will not affect features but will improve the overall system performance.
– System Menu 4.3v2 compatibility (September 8th, 2010 update)
– New savefile redirection feature
