It remains a pretty impressive-looking game, right?

Sega 156 user gasega68k is the one who developed pseudo-Mode 7 under the Genesis hardware limitations, and he explained how he managed to pull it off in a forum thread from a while back:

Hi, this is a demo of rotation and scaling better known by the name of "Mode 7".

I'm using the external Ram 64Kb in Word mode, to use as a "virtual map" of 256 x 256 8bit (256 colors "simulated" as in Wolf3D), the idea is that when we move on the map, it will uploading new "tiles" (a size of 8 x 8 = 64 bytes), similar to what is done for normal scroll, but as "tiles" of 64 bytes.

Unfortunately, this will not work with flashcarts, since they do not support word-wide in Sram.


In practice, here's what it looks like:

It's not quite F-Zero on the SNES, but it's surprisingly close!
