I found an old PC-6001mkII tape labelled "DEMO" which turns out to contain this demonstration program. There are some graphical glitches, which seem to be due to errors in my decoding process so I'm still working on getting a clean dump from it. www.youtube.com/watch?v=gyGZ...

Over the last couple of weeks I've been making a NES game where you use rocket exhaust to both move around and burn holes through obstacles. #nesdev

I uploaded a new 60hz capture of the NES game I made with @prismbeings.com last year, since the old capture played back at 30hz on YouTube... www.youtube.com/watch?v=Xr-S...

Procedurally generating a Yin-Yang symbol in 128 bytes on MSX2. #msx

"Full Moon", a 256-byte effect for MSX2. No trigonometry necessary. For this one it was kinda tricky to get the raster timings consistent across the machines and emulators I tried. Download: fizzer.neocities.org/msx/fullmoon... Run it in your browser: webmsx.org?DISKA_FILES_... #msx

I made another effect for MSX2 - all of the code and data fit into less than 256 bytes. By the way, I took the sprite graphics (which take up 32 bytes of space) from the 1984 MSX game "ChoroQ". Download: fizzer.neocities.org/msx/offroad.... Run it in your browser: webmsx.org?DISKA_FILES_... #msx

Another small effect for MSX2, this time it's a star field in 128 bytes. By the way, both this effect and the previous one exit back to MSX-BASIC gracefully on any keypress. Download: fizzer.neocities.org/msx/starfiel... Run it in your browser: webmsx.org?DISKA_FILES_... #msx

I made an effect similar to the old "Mystify Your Mind" screensaver, for MSX2 and in 256 bytes. Download: fizzer.neocities.org/msx/mystify.... Run it in your browser: webmsx.org?DISKA_FILES_... #msx

I made an improved version of an older Boing Ball demo I made for MSX2. This version is for MSX2+, for the sole reason that MSX2+ has horizontal scrolling. www.youtube.com/watch?v=9B8n... #msx

The topic of raycasting on MSX has come up. A while ago I made a renderer for MSX 1 which looks like a raycaster (so-called backwards projection) but in fact it's a rasterizer (forward projection). This reduces the per-column cost significantly. Doom worked this way. www.youtube.com/watch?v=8l52...

I discovered something interesting in the MSX2 version of Pac-Mania. The game has an isometric perspective just like the arcade original, but it first loads the background with an orthogonal perspective and then applies a shear effect to it in VRAM. The original simply loads pre-sheared tiles. #msx

By the way, I'm working on a port of Another World to MSX (most likely a TurboR). Here is a test of the intro using a polygon streamer I made earlier: www.youtube.com/watch?v=uTGn...

I made an attempt to create this kind of material. Also, this is the first shader I'm posting about on this new Bluesky account! www.shadertoy.com/view/Wfs3RN

It turns out that everyone is on Bluesky and I had no idea.
