Bad news, same result on 1.5 as in the previous version (copied prx and at3 to MS root, the 2 game directories to PSP/GAME).

Black screen, no reaction to any button, have to hold power button to shut it off.

Any news on this?
I assume hitchhikr is very busy, what with the kernel hack, but hardware decoding of mp3 streams would be very useful to a lot of developers (myself included), I don't think there is any way to do it currently, and software mp3 decoding takes quite a chunk of processor cycles.

I haven't taken a look to the mp3 thing again, and i guess that even if hitchhikr was not busy, he could have more problems in finding this in 2.60.

I hope to get some time some day in the future :)

as codes:
0x1000 is atrac3plus
0x1001 is atrac3
0x1002 is mp3
0x1003 is aac
0x1004 might be wma in newer ME code (haven't checked)
