So I googled "psp dj software" for no good reason and found these two pretty cool apps:
QMixer (v1.2) -- http://www.qj.net/qjnet/psp/psp-homebre r-v12.html
Ruckus (MOD LE v1.1) -- http://psp.dashhacks.com/file/1492
They both seem pretty rough but have some cool options. Qmixer has easy loading of files to both decks, crossfader, and the ability to load your own "sound effects" to the face buttons. Ruckus has neat loop point settings and pitch controls but I can't figure out how to avoid gaps between files?
Any more cool shit like this I should know about?
