MaiAT3PlusDecoder (new at3+ decoder) by cooljacker at 10:58 AM EDT on May 30, 2013
So it looks like the Sony code is removed but it's not done properly to be an open source decoder, I get that impression by reading the thread, I know shit about reversed engineering... and programming as a whole lol: http://forums.ppsspp.org/showthread.php?tid=3707
source (it has mini player daaaaamn): http://sourceforge.net/projects/maiat3plusdec/
plugin for ppsspp emulator is already compiled: https://docs.google.com/file/d/0B1ftGc2t9-dZQ2daRTkwM3NQREE/edit
but actually, what about that 'mini player' for windows the source has, can somebody make that shit? Would be great to play some extracted psp music...
Compiled mini player for windows yesterday(MinGW, like I said). It worked well(note it's a command-line player) for 2ch .at3, but will show error message on 6ch .at3....
