AGA still was giving me issues, spent all Saturday trying to fix issue. Finally got the issue I kept hitting 14 years ago sorted. AGA now works 100% perfect.
I then ended up getting side tracked. Spent all day Sunday implementing MP3 player for menu. Basically as we have paula on ME CPU. When in menu, the thread keeps running the sound output, buffering no audio. So as its still running, I thought, why not switch the inputs while in menu to ME MP3 hardware decoder. Got all code sorted, however not working. Ended up debugging til very late. As I was about to shut down PC, I found out, we have to start a few kernel modules on PSP, namely the one that deals with ME MP3 play back.
Well at 2am this morning, finally got MP3 playback working.
Its still rough around the edges. It seems to play ok, through the paula output stuff. Just have a spike around every 2 secs of playback, nothing major. Needs buffer tweaks.
So now, when pspuae runs. Paula does all the amiga sound. You enter menu, then it internally switches from paula to ME Hardware MP3 decoder. Exit menu, it switches back to paula. Its working really well.
Once, I have it perfect, will switch back to CPU, blitter and copper stuff. This sidetrack was very frustrating, as there are loads of different pspsdk's with different headers. So it made it challenging, but fun.
Fun side note, ME CPU also does different formats. So could tweak it to accept, WAV, ATRAC3, WMA. Could even use it to play videos in the background of menu.
