I looked around at porting Vogtinator's nCrafti to the Sega Dreamcast and here it is !
It's a Minecraft clone programmed by Vogtinator for the Ti Nspire CX : a very limited calculator with a weak ARM cpu. (clocked at 132 Mhz !)
It is entirely software renderered : No OpenGL, only a framebuffer.
The Dreamcast port runs okay and does not make use of the PowerVR GPU.
No enemies are available but you do get Redstone and TNT blocks !
Grab it while it's hot :
CDI file

Plain files (for SD cards)

Burn the CDI file and you're good to go !
There's no music, since it was slowing down the game (it requires a lot of RAM as well) but there are some sound effects.
