Woogal has updated his port of Duke Nukem 3D for the GP2x.

Changes:

Cutscene movies now work (used to cause black screen crashes before).
Because movies work, this means episode 4 (The Birth) is now playable.
Function of A and B buttons switched to match other software.
Pressing ‘back’ (was B, now A) on the main menu no longer locks the game out.
Music and sound device settings hard coded as there is only one possible sound device
