DeNitro and Devin923 have released PSPRevolution ? an amazing new game for the PSP. It is very simple to play, you just press the directional buttons in sync with the beat, but it is very addicting. This is the most fun homebrew game I have played in a long time guys, I am very impressed. Good work!!<br><br>PSP Revolution is based off the popular game Stepmania and is compatible with Stepmania (.SM) and Dance With Intensity (.DWI) song files. To install additional songs, copy them into pack folders in "\psp\game\pspr\songs" just as you would in Stepmania.
