i understand. one additional problem with texturemapping on agb is the low
display resolution.

our game can be roughly compared to afterburner or galaxy force.
so no number crunching like in real 3d scenes. only for collsions
and prespective translation some math is needed. all other perspective
stuff like texturing ceiling & floor and doing a perspective sky is
done with the hardware capabilities.

i'm fell more convinced to use the agb as a piece of special hardware
like the amiga then a number crunching device that it obviously is not.
