so i heard there was a homebrew app. that lets u listen to music while playing a game. can anyone tell me what its called and how to install it? thanks

Yeah i would like to know how to do this aswell ?

Well iRShell used to do it but once it hit 3.03oe-c it stopped working properly. A new iRShell is in the making so I belive that will be fixed.

Dont worry get the irsmp3. its a prx plugin that allows you to play. but it has to feature overclock your psp which you need to do because other wise the music will sound shitty. here is the plugin http://www.sendspace.com/file/l4zfyv

anything for devhook?

If you're using DevHook you should be able to listen to MP3 while playing a game using iR Shell.

i use this myself. works great. nothing like playing Ratchet & Clank to Early Mornin Stoned Pimp
