Re: Doom floor texturing

Yep, the DSP textures concept is really great. You can optimize it to death, leaving only a jump tree with lots of:

move.w (a0),(a1)+ ; a0 = $FFFFA206

on CPU side (the whole tree is in instruction cache, of course!). If you time it carefully, it can run even on 040+. Of course, Hatari developers are not very happy about such practices as it requires really 1:1 cycle timing emulation ;-)
