Wolfenstein 3D IS technically possible on stock A500 shocker!

Planar graphics, we has them!

From a CPU perspective, it's a go; the 68000 will most likely perform just as well as an old 286.

AFAIK EGA was also planar based.
The Catacomb Abyss uses only ega and has texture mapping just like Wolfenstein 3d.
