Re: VERA FX demos for VCF

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...

Re: Color Wheel (~400 colors, low-res and hi-res)

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...

Re: Color Wheel (~400 colors, low-res and hi-res)

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...

Color Wheel (~400 colors, low-res and hi-res)

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...

Re: VERA FX demos for VCF

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...

Re: VERA FX demos for VCF

Is Mario Kart for real or a cheat ? The 2Mb requirement made me wonder ; there's a pretty demo on here which looks spectacularly 3D but is really just all pre-calculated and rendered simply on the fly ; it's not doing 3D in real time. Not knocking the project, looks great ; things that Vera was rub...

Re: Mini Motors

As long as you dont set DCSEL to anything other than 0 or 1 (or 63), the VERA FX should not act any differently than the older VERA firmware.

This sounds like a difference between emulator and hardware. To be entirely sure you would have to check on the older VERA firmware to compare.
