I'm Paul, an indie software developer and retro machine lover; especially the C64! I also do 3d printing when I can, but my printer is in storage right now.

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

Luke Skywalker, drawn ✏️ by me in 5B pencil only.
Drawn on 8"x12" paper, 2018.
I don't care what anyone says, his character is perfect as a cynical, new, beardy Yoda for the sequels. Fight me.

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! :)

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!

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.
