GMU was developed completely separately from Open2X itself. It is a nice music player once you get used to it. One thing that might help you is to look at the readme.txt for it, or maybe just look directly in the configuration file for the input assignments. You might just download GMU from the archive, extract it, and look at the files that way. Or, just download another music player and install it on an SD and use that instead.
Thanks - it is a nice player - guess I'm just struggling with so much new stuff so quickly - must be my age
Thanks again for this release from the open2x team, o/s seems very stable, quick to startup and once I get used the gmenu2x I think I'll be much happier B)
Given more time I'd like to help out with this, but my work (funnily enough I do a bit of linux o/s 'hacking' for software I do) and home life severely limits my spare time :huh:
