Add support MP3 as BGM

[onelight]

OK, thank you.

To further investigate, I would also need a JpcspTrace from a real PSP. Add the following lines to JpcspTrace.config:

Code:

sceMp3Init 0x44E07129 1
sceMp3GetSamplingRate 0x8F450998 1
sceMp3GetMaxOutputSample 0x87C263D1 1
sceMp3GetFrameNum 0x3548AEC8 1
sceMp3CheckStreamDataNeeded 0xD0A56296 1
sceMp3GetInfoToAddStreamData 0xA703FE0F 4 xppp
sceMp3NotifyAddStreamData 0x0DB149F4 2 xx
sceMp3Decode 0xD021C0FB 2 xp
sceMp3GetBitRate 0x87677E40 1
sceMp3SetLoopNum 0x3CEF484F 2
sceMp3GetSumDecodedSample 0x354D27EA 1
sceMp3ReleaseMp3Handle 0xF5478233 1
sceMp3ReserveMp3Handle 0x07EC321A 1

From the code of "AKB1/149: Love Election", it only accepts MP3 with a bit rate of 44100, others are rejected by the game itself.

I try add that lines to JpcspTrace.config, after that I can't run games in my PSP.
"AKB1/149: Love Election", it only accepts MP3 with a bit rate of 44100,
it is true, but if you run AKB1/149: Love Election with jpcsp, it will rejected all mp3.
text Project DIVA Extend in my PSP
can load 48000 kHz MP3 , also can load 44100kHz mp3. and load mp3 is faster than jpcsp.
