I've rewritten my #Console8 logo player -also works on #AgonLight - and updated the video file for 2 reasons. 1. it was a bit long playing the whole thing, and 2. I wanted to play a higher resolution video, covering as much of the screen as possible. With a bit of video editing (cutting and cropping to make the most of the logo at the end), plus taking advantage of the VDP code for both decompression and bitmap expansion, this is what my boot sequence looks like. I've left the logo to linger a little, but that's optional and a quick change to the script.

Retroparty war wieder genial ❤️
Da wir an die Kapazitätsgrenze geraten, wird die nächste wohl an einer anderen Location stattfinden. Dieses mal stand die Party unter dem Motto Atari. Ich hoffe ein paar Amiganer konnten Vorurteile abbauen, ich schon 😉https://retrocomputer-dresden.de/retroparty-2026-one/

Der AgonLight ist kein Raspberry Pi, sondern ein echter 8-Bit-Computer mit „Bare-Metal“-Design. Er kombiniert eine 50 MHz eZ80-CPU von Zilog mit einem ESP32 als Grafik- und Sound-Co-Prozessor.
Bootet in Millisekunden direkt in BBC BASIC. Wer Technik ohne Abstraktions-Layer verstehen will, bekommt hier direkten Zugriff auf CPU, Speicher und Register.https://retrocomputer-dresden.de/agonlight_intro/

Time for another image viewer for #AgonLight #Console8 - this time, PCX format. There are a number of reasons why I chose to display this format on the Agon/Console8.
* It is an already existing format
* The format is supported by modern tools, including #GIMP
* It uses a very simple form of compression ideal for 8 bit CPUs
* The specific choice of 16 colours has additional benefits:
* The 16 colours are chosen from within the available 64 colour palette
* The 16 colours allows the image to be sent to the VDP with 2 pixels per byte, speeding up the transfer
I've attached a sample here to show just the quality of the resolution and colour depth. #z80 source code and binary is at:

I recently took advantage of some temporary discounts and acquired the #Console8 by Heber. It's a #retrogame focused package of the #AgonLight, complete with some great joypads that they also make. As part of the induction into the house, I converted the logo into something a little more 8-bit, and updated my logo software. #z80 #ez80 #retrocomputing
You can buy a Console8 here : https://heber.co.uk/agon-cosole8/
You can download the updated logo software & source here: https://github.com/sijnstra/agon-projects/tree/main/bootlogo -

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 that can be improved. It has a dependency on sjasm+, so there are a few quirks in how I've had to pull together the Agon libraries. You also need a Pascal compiler to compile the compiler. All the instructions, source and some examples are on the github repo: https://github.com/sijnstra/pasta80/tree/agon #retrocomputing

If you're into 8-bit programming and/or graphics you can get a whole range of Retro Jotters on Amazon. The most popular one is the ZX Spectrum one which I've linked here... https://www.amazon.co.uk/dp/B0C47JD15H Good luck with finding the others as the site search engine is absolutely useless. #zxspectrum #retrojotter #c64 #agonlight #amstradcpc #gamingbooks #gamedev #art #pixelart #puttycad

Creating an Entity Component System for My Retro Video Game Engine
Welcome to the next edition of Gamedev The Hard Way, my attempt at #programming a game from scratch for the #AgonLight, using nothing but C. This time I throw away a ton of code and replace it with a shiny new Entity Component System.

I wanted to use more graphics on my #AgonLight and the best project that came to mind was to display #Amstrad #CPC .pal/.scr images. Took a while to get there, and now it works including the same "wipe" effect that the original hardware had due to the unusual RAM layout. Planning to use this for landing pages to create the mood for any game you might load. You can see the source code + binary at https://github.com/sijnstra/agon-projects/tree/main/CPCpic #z80 #ez80 #retrocomputing #retrogaming video shows loader image from Stefan Vogt's Ghosts of Blackwood Manor.

Writing a Roguelike in C Part 1
Let’s try to write a Roguelike game in C for the #AgonLight. This is the first video. I explore how the original Rogue and similar games like Nethack generate their own dungeons, then adapt code that draws mazes so my dungeons are a bit more interesting to explore.
