My multi-cpu assembler, OmniAsm now supports the GB CPU as well as Z80 and 6502!! I still need to tweak the parsing of some opcodes like (FF00+XX) and SP+XX, for example, but I think the rest are working :)

I've added interrupts into my OmniPas tool, my Pascal -> Z80 cross-compiler :) You can hook up to the vBlank interrupt, and also wait for the vertical blank! #zxreposts #zx #z80

Interrupts: Z80 Assembly Language for the ZX Spectrum, Episode 12 YouTube video by The Retro Desk

Sweet! I managed to get this move a sprite using interrupts example working with my own Z80 assembler (needed some slight code upgrades)...I'm very happy! I'll now try something similar with my Pascal -> Z80 cross-compiler!

c64 prototyping...some scrolling with split screen HUD at the bottom. It only works in PAL right now, NTSC flickers (not enough raster time??), but is a milestone for me still! :)

Oh, there is a free demo too...

Thanks! 😊🙏

Cool!

Spectrum Next #Delphian progress: working on the 3D engine. unclipped triangles are now working. It's using DMA to fill lines, and just CPU on short lines. Some more optimisations to be done, but at least it's working. Next comes all the clipped polygons!🙂 No problemo!😉

Super Sunny World (my upcoming NES platformer) will have a number of hidden items required to reach 100% completion.

To make this more manageable, I've included a stats page with a breakdown per level of what you are missing!

Assembly - Patching 68K software - SimpleText Someone asked to have SimpleText open a smaller text window at startup. Initially, I assumed this would be a fairly easy fix by just overwriting a few constant values in SimpleText code. It turned out to be a pain -- but I learned a lot along the way. You need to have the code editor (from one...

ROGUEish by syntaxerrorsoftware A rogue-like for the c64!

@ausretrogamer.bsky.social did you see that I've recently released a rogue-like called ROGUEish on the C64? It's available as a digital and physical (tape, Disk) purchase 😊

If you always thought that the #C128 is just a #C64 with a bunch of useless bits bolted on, maybe it's time to reconsider. I just released a version of Stunt Car Racer adapted to take advantage of these additional features, and the performance boost is quite significant. See for yourself!
