You misunderstand what 'shareware' means. The answer is 'no'.
In general, if you take source-code for some game and want it converted to dingux, you should verify:
- if it uses cross-platform libraries for video/audio/input e.g. SDL and make sure these libraries are supported in dingux
- if it uses low resolution like 320x200 or 320x240, otherwise you'll need to code a downscaler yourself
Then you could try to compile it with cross-toolchain and to correct numerous errors you most probably encounter. If you are done with it, do more test on real device and eliminate some more obscure bugs and voila, your own port is ready.
