Commander X16

Demo part: Rotazoomer The very first demo part I tried to implement was the Rotazoomer. The reason for this is quite simple: the FX affine helper natively supports translation, scaling and (with some generated tables) rotation as well. So this should be one of the easiest demo parts to replicate on...

The making of Second Reality X16 During the development of the 2R demo remake MooingLemur and I shared quite a few screenshots/videos of in-between results of parts of this demo and we had quite some discussions about those that show partially working/buggy demo-parts and (partially) reverse engine...

Created a new repo:

https://github.com/visual-trials/SuperM ... /tree/main

It now runs on a X16 with 512kB.

It can now be assembled with cl65. See instructions in mario_kart.s

Small update. I have separated the Mario Kart demo code into its own file and cleaned it up into something more readable here: https://github.com/visual-trials/X16-Hardware-Tests/blob/master/fx_tests/mario_kart.s At the top of that file there are instructions to build and run it. A few things of not...

How did you draw the polygons? I drew them in Python (pygame) first to re-create the original image/bitmap. Then I tiled it so the X16 could fit it into vram. This was to make sure that I had 396 colors. The problem with the original image is that its basicly a jpeg with many thousands of colors. I...

To give you an idea what are the top and bottom 142 polygons look here: image-6.png The top 142 yellow polygons share the same palette indexes as the bottom cyan polygons. In the gap between them, the palette is modified each frame. And at the end of each frame (so below the cyan polygons) the palet...

This is a demo showing a colorwheel with around 400 colors. # Low res screenshot low-res_screenshot.png # High res screenshot high-res_screenshot.png This was done by re-creating the original image by re-drawing all polygons (diamonds) and sorting all colors from top to bottom (which is 396 colors e...

Here are some videos (not mine) showing the demos running on real HW:





Note: music in those videos is post-edit

Awesome :) Do you think you'll release the source for these demos as well? It would be a good example of how to use the FX features. The source is already available on my GitHub. Its not (at all) cleaned up yet: its part of a hardware test suite right now. (GitHub link : Mario Kart is in "tile...
