Where is SCREEN_WIDTH defined? I cannot seem to find its definition anywhere but you use it in nspirevideo and sdl uses it in joystick.

Wow that looks great. :D When this is available for download, I need to try the color version to see how this looks like on my CX (assuming a demo of the above is made available?). :D
Of course!  :D

CX:

Touchpad/Clickpad:
http://www.mediafire.com/?ax8dyd9xqgjb2z5

And here's the source (just ignore my dirty random generator at the end):
http://pastebin.com/gqjXDTBw

Also, please note that the actual code that generates the plasma effect was not made by me, this is just a port of a demo available here.

Trying to recompile the plasma demo, I get an undefined reference to the sinus function.
How did you do?

Thanks.

Newlib's math library doesn't work, so you have to use another library. In fact you need to use fdlibm compiled for the TI-Nspire, which you can find here. (I suggest including fdlibm.h rather than math.h, but both should work since they should be pretty much identical)

fdlibm eh? Gotta try on the Prizm. Unless someone manages to make it work with newlib.

Yeah you should be able to compile it easily using the code from here. I'm not sure if there are any issues with globals on the Prizm, but that code should compile perfectly on any platform, just edit the Makefile a bit (and rename the resulting libm.a to libfdm.a to avoid doubts and name collisions). Oh and in fdlibm.h, remove the #ifdef _TINSPIRE/#endif at the top.

Damn that's awesome!

EDIT:
I edited the voxel demo a bit (nearly tripled range, made mountains much bigger and imposing, made it run full screen, added Mars-like colors and some other adjustments):


I've attached the download (yes, I know it's massive, it's because I couldn't bother to reduce the gigantic trig lookup table). Code's here. Check it out, tell me how it runs (on the Touchpad it seems to be pretty smooth, but it's hard to tell with the shitty LCD).

Controls are arrow keys to move, 5 toggle noclip, and +/- to increase/decrease altitude when in noclip.

EDIT2: Added a porting tips page in the wiki.

so I heard that there's a gba emulator using SDL or something (at least I think that's what calc84maniac said before). Will it be possible to port it to nspire?

I'm already porting it (and I removed all SDL references as well, since it's mainly used for the framebuffer)

If I'm thinking of the same emulator, it's written in C++.

Do many things have to be changed/rewritten ?

You're not thinking of the same emulator. This is the GP2X/Wiz version of gpSP.
