Has anyone come up with a convenient way of converting MP3s etc. into AT3 files that the PSP will play from the MUSIC menu? Using Sonys own software works, but it's pretty limited & cumbersome. Now that 2.0 actually plays them off Pro-Duos, it's suddenly a lot more useful and as AT3 has a much better quality:size ratio than MP3 does, it might be good to bung a few tracks on there in case my MP3 player runs out of juice.

Exact audio copy psp edition may help. Some guy has converted his music using this software and replaced with soundtracks in burnout.

EAC-PSP Ed (which is a heavily cut-down version of the normal EAC tool) converts to Atrac files, but they've got to be in some wierd folder structure, which only SonicStage seems to be able to produce, it makes some sort of encryption key it stores in another folder for the MagicGate stupidity.

Does anyone have a download link for it?
