tmp folder

[megaten666]

its normal when play a few files inside tmp folder of JPCSP..start to fill up with Mpeg folders ..

i have sonic stage and decode options

Yes, it is normal, once Sonic stage decoded an at3 or pmf file, wav and oma files starting to pop up in tmp. You may notice a short lag when a music first starts to play. During lag, Sonic stage is in action, and the next time you hear that music/voice, lag don't occur, because at3 already decoded, and JPCSP just read the wav file in the tmp folder. So, if you delete the tmp folder, sonic stage has to decode everything again.

Sadly, if you play a lot of games, tmp's size can be pretty big. Mine is 5gb already, filled with different wav files. Although, according to my research (i'm not part of the dev team though), you can convert mpeg's extaudio.wav files to mp3-s with given specifications, saving some space. But this is another story (tested on Persona 1 remake, the game's opening was 20Mb in wav, after conversion 3 Mb in mp3, big difference for my little HDD )
