Mode7 project, who wants to help?

first of all, I can remember from magazines that the bloody super nintendo got a crappy geometric engine for zooming and rotating, while MD didn't.
sencondly, have a look on what I did quite easly in Macromedia Flash 8:
www.gotoandplay.it/_articles/2006/09/mode7racing.php
there's the sourcecode for whoever wants to read more on it and see how it works.
In flash that have native and ultrafast maskings, it's quite a kid job, but without the possibility of loading the same jpeg 50 times on the screen and to let see only a tiny horizontal stripe of each of those fifty... it becames hard to think.
I think from the little I've seen in examples, that we can create a big raster of our race track, and some horizontal stripes that copy a only a portion of the complete full track. If we can do this, an if we can rotate the data stored (since flipper games, bouncing, fallings and easings exists on MD, trigonometry must have been implemented O__O) we're done.
Someone is interested in trying to develope this kind o fake3d game with me? I'm available to explain, if necessary what is needed, but I need someone who already know how to beat the shit out of the MD cpu

I remember now that someone made a very bad looking version of dukenukem3d, using very bad looking raycasting (it smells to me that was the edge limit pushing for the MD specs)... but raycasting implies that they used some handmade masking of textures... so my idea of using it for a F-zero, or wacky wheels clone is not impossible! what do you think?

Raycasting floors is MUCH slower than raycasting walls, but, in theory, it could work on the Sega Genesis.
I think Fonzie made something like that.

The Sega CD has a Mode 7 that you can use. There's a game on the SCD called BC Racers that uses it and it looks similar to Mario Kart for the SNES.
