I've been trying to work on a few projects with libxenon and SDL, but as soon as I tried to load most ELFs from (for example) IUNIXI libxenon examples repo and lantus sdlquake I either just get returned back to Xell or the xbox simply freezes. I also tried using an external hard drive disk to run the ELFs (since I don't have a USB at the moment) directly with Xell with no luck whatsoever.
Here's a list of the programs which do run on with (apparently) no problems:
GPU_Rand (sort of, it does when I use aurora to run it)
SDLSample
cube
And a simple hello world test.
The rest of the files just crashed, showed weird graphics, returned back to xell, or (in the case of BasicRendering) all of those at the same time.
