Is iR Shell overkill for the simple listening need of your own tunes while in game? You may recollect joek2100’s initial release of irsmp3, a modified version of iR Shell’s open source mp3 module. After receiving many new features & optimizations, Music PRX debuts with its new name at version 0.50. A few things to note…

This has new hardware decoder will work with all umd games/the vsh/ and most homebrew. (Thanks to cooleyes)
- It will not work with homebrew that uses the ME (SnesTYL ME, dosbox .71, etc)
- It will not work with copy protected atrac3’s
- In the next release I’ll have it switch back to the software decoder (mp3 only) when the ME is in use, but until then you’ll have to use the non-ME version
- Also when playing an mp3 that has a samplerate different from 44.1kHz, you need to pause the song before the vsh’s video/music player will work

0.50 changelog:

• Added In Game mute
• Added a HW decoder (thanks to cooleyes), which should make playback faster
• Fixed various bugs, overclocking the vsh browser now works
• Added wave atrac3 (*.at3) and sonic stage atrac3 (*.oma/*.omg/*.aa3) support (only with non copy protected files, but you should be able to remove copy protection with the newer sonic stage)
• Added support for music copied to the psp using sonic stage (in OMGAUDIO)
• Changed how the cpu is changed, it is now based on the current speed, even if some other program changed it
• CPU + Mode settings are now saved, (if a game changes the cpu speed, it isn’t saved, but if you change the speed it will be saved, also nothing prevents a game from changing the speed after its set)
• Added support for mp3’s at samplerates != 44.1kHz
• Added a loop current song button
