I ported my fork of #z80ai to #ZXSpectrum. Now it indeed ran at 3.5MHz (CP/M version on #ZXSpectrumNext must have been using 28Mhz). This simple convo took takes 4.5 minutes :) (Optimizations are surely possible. I also pessimized it a bit by adding […] [Original post on mastodon.gamedev.place]

It is of course very primitive. If you have #zxspectrumnext , you can run examples out of the box in the Next standard CP/M (you may need to build CHAT.COM but it's a breeze). At 3.5Mhz the token generation speed isn't great of course. #z80ai

Ok, so here is a working 40KB language model for Z80. It mght be a good occasion to put the tech under the microscope and understand it through and through. https://github.com/HarryR/z80ai

A bunch of sceners hanging out on #zxgfx telegram channel, yours truly included, decided to animate works of Grongy, a profilic (and young) #zxspectrum artist, for his 25th birthday https://youtu.be/1uw_yvexgnc?si=J2NX3oKkHKr2b6m9 Of course this is a demo, not a pure anim, and most scenes […]

Muzyka pop przed Chrystusem. Pop Before Christ. #z80 code embedded in a Czech text translated to Polish (perhaps indirectly through Enlgish).

Time for another programming option for the #AgonLight family... #Pascal! I've re-targeted PASTA/80, an open source Turbo Pascal 3 compatible cross-compiler that targets #z80 machines. It's still early days, so expect a lot of weirdness and issues, and things […] [Original post on hachyderm.io]

What a marvel. I saw its tech demo, nice to see it developed into a fully fledged game. Probably the fastest 3D game on Speccy. https://www.indieretronews.com/2025/11/world-of-spells-this-first-person.html?spref=tw

RE: https://mastodon.social/@voiceoftheoldways/115515509360079602 This immediately reminded me of this recent picture: https://zxart.ee/eng/authors/k/kuinji/swamp1/

I don't like it when someone insists on clang-format. This desire to reduce mental work by removing variance stems from the same root as desire to remove spelling variance, variance of usernames, approaches (DRY)... where does it stop? Some cultures go as far as to regulate people's names […]

We released a ZX Spectrum Next demo, probably the first fully fledged demo for the platform (not an intro, not a port, etc) despite its 8 year history. It stays true to its ZX Spectrum heritage using 256x192 video mode (which is also much easier to handle on a 8-bit platform) with 128x96 […]

If you draw with the stack pointer by only pushing into the stack (e.g. a full-screen rotozoomer), you can do it with the interrupts enabled! You may need to only disable interrupts for the last element, especially if you use your own stack for the ISR routine, so only its return address can […]
