SA-1 3D Object/Polygon System

This system I'm been coding for... over two weeks I think, adds some basic 3D support using SA-1. I just used SMW as a base, however, you can't really have 3D stages and gameplay with the system yet. As you can see it can load some 3D objects and do all kind of basic rotation and translation on X, Y and Z axis. The objects are imported from a .obj file and it can be any, the only issue is really the frame rate. Mario uses around 200 polygons and the system runs at only 5 FPS and there is absolutely no texture support. Also it suffers gimbal lock, where the rotations can make no sense depending on the order you apply them, unfortunately it's rather hard to fix due of the limited RAM I had available. The internal resolution here is 256x96, I used HDMA to enlarge the screen vertically however each pixel actually occupies two pixels at once, so the real resolution is 128x96 scaled to 256x192. The graphics are 4bpp, converted by SA-1 Character Conversion DMA 1, however with some adaptation you can make it 8bpp using a mode 7 layer as long you adjust the DMA addresses since mode 7 has an odd horizontal alignment. The SA-1 CPU does not have any plotting function unlike Super FX, but using Character Conversion DMA and math it's possible to make 3D drawing though software. I coded two 2d polygon renderer where manually it draws the polygons to a frame buffer where it's sent to VRAM and a drawing code that takes 3D polygons, transforms into 2D polygons and sends to the Z-buffer/sorter which sorts the polygons for proper back/front drawing and then it just sends to the 2D renderer. With a bit of effort maybe it's possible to make some simple 3D stages for Super Mario World, using SNES CPU for processing the game logic while SA-1 take cares of the drawing + rendering. But don't expect any high detailed game like Super Mario 64, since SA-1 in first place is not a GPU, just a CPU, so everything graphical related is done by software and second it's clocked at 10.74 MHz, which is pretty low for 3D rendering, specially in software. Super FX may be able to render it, though, due of the built-in 2D plot functions and the high RISC clock (21.477 MHz) which is twice faster compared to SA-1. Still, it's interesting to see 3D drawing in a SNES without using Super FX. Download link: https://www.dropbox.com/s/9rek9yyr58u...
