OpenJazz - http://www.alister.eu/jazz/oj/
An engine to run the classic Jazz Jackrabbit game on various devices and computers.
There are already released versions for GP2X, GP2X Wiz, GP32, the latter which is made by our own Slaanesh.
Doesn't seem to hard to port it to Dingoo/Dingux, since the GP2X, GP2X Wiz and the GP32 already have all the code available.
Unfortunately, our beloved Slaanesh is busy with porting DOSBox, and I'm guessing he's got other things to do aswell.
Would be great if this was brought to the Dingoo!
You can get the source via SVN, if anyone wants to have a quick look over it.https://openjazz.svn.sourceforge.net/svnroot/openjazz
