I've opened up my Blood Money article where I talk about the multiplexor used in it. Based on the wonderful Armalyte multiplexor, it made it super flexible and quick.

I look at #Commodore64 "Cyberdyne Warrior", released in 1989, created by the Rowlands brothers. Many colours, wipes and fades, distinctive sound style, multiplexed sprites with expansion, and sprite background priority effects.

An animated loop basd on the games of the ZX Spectrum 8 bit micro from the 1980s
This was made in photoshop and Blender and just a fun little tribute to my all time favourite home computer

I look at Commodore 64 "Hard Drivin'" published in 1989 by Domark. Using double buffered bitmaps, road draw fake 3D, fake 3D object draw, "rotation" is pre-calculated, and the "rotation" memory used.

Pong Wars simulation for Acorn Electron and BBC Micro/Master. This fun little project was inspired by pong-wars.koenvangilst.nl. After coding a prototype in BBC BASIC, I created this 6502 asm version. I hope you enjoy! github.com/0xC0DE6502/p...

I take a look at #Commodore64 "Arctic Shipwreck". Published by Commodore in 1983, developed by F°451 Software with music by Marton Saghegyi. It has a really nice iceberg draw, an early example of a sprite sheet, and you play a mammoth!

In this video I take a look at #Commodore64 "H.E.R.O." from 1984. I look at how extended colour mode is used, which is quite unusual to see in a game.

I've just released !EliteNet, my first #RISCOS application in 30 years.
It allows #Archimedes #Elite to transmit to an #Econet multiplayer scoreboard (see Yoda’s score).
I’ve loved every minute of this little side project!

It's been a minute between updates on infeZtation 2 (aka infe2tation). I've designed the first 10 levels, added lots of info to the HUD (graphically it's WIP), power ups, scoring, some more enemy types, lots of bug fixes. Development is going well, lots more to do! #c64 #commodore64 #8bit #retrogame
