I might be wrong, but if I remember the source code correctly. So is the generic one running in 1.5 kernel mode. While the psp290 version is running in 3.xx user mode.
This sounds a bit weird. As far I know the config "read" method shouldn't have any problems with unknown keys. This needs to be investigated.
This is the hidden autoplay feature :-) Nah, good find. I'll fix that.
This is really the thing I need to fix in next version. I need to actually scan the music folder a bit better and build sorted playlist. Now it just reads the files and plays them as they are "listed". Not really a good solution there at the moment.
Yeah, I've been using that code as reference a few times already. It was actually the music.prx that gave me the idea/inspiration for this mp3 mod.
Cheers
