I also have mpega060.library (is that the right name?)
You must rename it to mpega.library. I'm using Prayer2 and it runs flawlessly at 44kHz. You must use any 31kHz screen -DBPal, etc.- so you can play at this rate.
Other players are SongPlayer, DeliTracker, Play16... The last one is CLI based, so you could use it to test if everything is in its place (AHI, mpega.lib, etc.)
Saluditos,
