Software
Mpxplay.
Excelent program for MP3 in DOS.
I made modifications in two part of this program: in display and keyboard modules.
In display module the information (song title, artist, etc) is send to GBA.
In Keyboard module the numeric keystrokes are intercepted in order to emulate
a cellular keyboard like Nokia, pj if you press "999337777" is like you have
press "yes". This is the modified program mpxplay
