sakya has updated his MP3 player LightMP3 for PSP.

Changes:

-Added: HP and RM on first line if headphones and/or remote controller are plugged.
-Added: the program checks the display brightness at startup and asks if you want to lower it
-Added: support to 22khz (plays fine with CPU at 40mhz), 24khz (plays fine with CPU at 40mhz) and 48khz mp3.
Note that to play 48khz mp3s the cpu must be raised to 80/85 mhz
-Added: Fastforward (no rewind, sorry). Press right and left to raise and lower playing speed.
-Added: volume bar
-Fixed: if you delete .scrobbler.log with LightMP3 running (activating USB), the file is recreated.
-Fixed: if the sample rate isn’t supported an error message is shown
