loop playback support

[hyakki]

Custom tracks on your games doesn't loop. I tried it with Dissidia. It plays once but then it stops. Here's the act3. I'm not gonna tell you how to do custom tracks. That's what google is for. This file replaces the Dissidia battle song only with a remix of blinded by light. I just wanted to test this out on the emu.

I don't think Jpcsp will support modified / compiled / rebuilt games (even if its only the audio changed, just because the file is .at3 doesn't mean its the same format as the original file was or has the same flags set (like loop))
Right now the main focus is trying to get normal games to work and loop properly without causing to many other issues, like looping sfx, voices ..etc.

instead of modifying the actual game, why don't you try going to the folder tmp\<gameid>\Atrac folder and find the audio file you want to change, then replace the corresponding .wav file with the audio file you want to use. (must be wav format) and jpcsp should use that audio instead.
