It's been bugging me for a while now and I finally decided to seek out an answer for my curiosity. If any of you know the Homebrew game: PSP Revolution you can probably describe it as the PSP's answer to the DDR call.
PSPR Downloads <-- to download
Now, as all avid StepMania players out there should know all StepMania's video files run off AVI. Seeing how the PSP does not support AVI playback I was wondering if anyone has tried to convert the files into MP4 and maybe the background video would show on PSPRev. I would try this myself but my XViD4PSP is acting up and it won't let me go past directshowsource.
If anyone has any answer, please let me know. Your help is greatly appreciated.
