Hi Savage!,
I already got it working.
As I had supposed it required SDL.dll compiled for WINCE.
The problem with putenv and getenv is that they are probably not available for WINCE, or they are implemented in a different DLL. as far as I found they are not available for WINCE according to MSDN.

I will make a post with my changes to the sources of JEDI-SDL to got it working ASAP.

The problem now is that the demos are not working, and still don't know why ...

Best regards,
