Creepy Crawly WIP on the Acorn Electron. Single screen buffer stress test. Decided to use MODE5 instead of MODE1 because I may need a second screen buffer later. This can easily run at 50fps but that just makes the sprite animations look weird

The creepy crawlies are coming... gaps or no gaps 😱

Playing around with Aseprite sprite editor, or: how to give yourself the creeps with only a handful of pixels 😅

I am delighted to announce the release of my latest project: Fully documented source code for The Sentinel, Geoff Crammond’s 1986 masterpiece. Here’s the repository; deep dives coming soon. See thread for details. 1/9 github.com/markmoxon/th... #retrocomputing #retrogaming #bbcmicro #c64 #8bit

Happy new retro year! This is going to be good fun for today

For the first time the Plus 1 Mini expansion unit for the Acorn Electron is available through Tindie! To celebrate, there's 5% off everything in my Tindie store until the 22nd using code RAMTOP5. www.tindie.com/products/408...

Ok, this is about as complete as it will get 😊 Here's a preview... I'll tidy up a few things (maybe change the music) and post on Stardot. 🔊

It's a bit early maybe, but Season's Greetings ! Many thanks for @0xc0de.bsky.social for the initial inspiration 😎 See the full video here: 😅 youtu.be/4hB7hUAY6p0 Now, back to Chuckulus ! 🙄

Now with a little more colour and nice chunky pixels! #acornelectron

Infinite amount of sand? Sure, let's go! #acornelectron

More sand, infinite stream, can't stop playing with this 😎

On to the next experiment with physics simulation on my Acorn Electron, creatively named Sand!

Couldn't help myself... my name fits exactly in those 36 bouncing balls 😎

Pushed my Acorn Electron a little further from 27 to 36 bouncing balls (9x9 pixels each, 50fps flicker-free, MODE4) 🤓

There is something very pleasing about arranging 6502 math code in such a way that most CLC/SEC instructions become unnecessary because the value of the carry flag is known in every possible execution path. It is also an excellent way to shoot yourself in the foot! 🤣

26

I can push this to 25 flicker-free bouncing balls (9x9 pixels each) at 50fps in MODE4 on an unexpanded Acorn Electron 😎 Can you do better? Might be fun to do much smaller balls/particles next... 🧐

Double the fun with double screen buffers, flicker-free 50fps #acornelectron

Always enjoy a little physics simulation, especially having stuff bounce around randomly, very mesmerising 😎 #acornelectron

Love this! #retrocomputing #coding

For fun I created a CRACKME for the Acorn Electron. With some neat tricks, like traps for all known emulators. The idea/challenge is to try to crack the protection code on a real Electron, using no modern tools. Unfortunately, while playing the hacker myself, I managed to crack it pretty quickly 🤣

Another great conversion of a classic game to the Acorn Electron! Very polished, well done!

Disassembly (+ comments) of tape protection of Repton (Acorn Electron). Interesting protection measures. Hidden data in tape block headers is my favourite trick github.com/0xC0DE6502/t...

I'm sure this has been done before, but I'm having fun disassembling the layers of protection code in Repton for the Acorn Electron. I may publish a commented disassembly later. There is fake code, many undocumented NOPs, hidden BRK handler, decryption, hidden data in tape header blocks, and more

Revisiting one of my older demos for the Acorn Electron. Creatively called "MODE2 Demo". Fixed an issue that made it glitch every so often. Runs flawlessly in Electroniq (and on a real Electron of course). If someone says the Elk is slow and lacking colours, show them this 😎

While coding Electroniq (Acorn Electron emulator) I got into the habit of writing down ideas, research, tech info, etc etc in a simple notes.txt file. This is now a 4300+ lines document and I'm very happy with it, considering my degrading memory and sparse comments in my source code 🤣

From tape protection rabbithole to disk protection rabbithole. This Acornsoft "Plus 3 Games" disc (stairwaytohell.com/electron/adf...) appears to contain only 2 small files, but upon boot you can still play 3 different games! The code in the !BOOT file is no match for modern emulators though 1/2

My custom tape loaders now confirmed working on a real Acorn Electron, including some lost bytes due to crippled MODE 1 🤣 I had trouble connecting my laptop (playuef, audacity) to my Electron, until I bought a cheap usb audio device aka "external soundcard". Loading/saving data works perfectly 😎

Anyone who has (or can make!) *original format* tape images (HQ UEF, WAV, etc) of Acorn Electron games that have tape protection and/or custom tape loaders, please get in touch 😎 Examples of games I am looking for in next post...

I was curious how game devs made custom tape loaders back in the day. Here is my disassembly (+comments) of the tape loader of Way of the Exploding Fist (Acorn Electron). It loads "encrypted" continuous streams, which are still made up of blocks so you can rewind & retry github.com/0xC0DE6502/c...

And here's a Speccy-inspired custom tape loader for the Acorn Electron (MODE 1, one continuous data stream)

I got sidetracked by custom tape loaders on the Acorn Electron and decided to try creating a few of my own. Here's one that loads a continuous data stream to the screen (MODE 0), scanline by scanline. Beware, this is the perfect world of emulators and must really be tested on actual hardware!

[email protected] it was decided on X that the Elk game 'The Hacker' would really benefit from your Blagger treatment 😉 (but not before you release Chuckulus of course!)

This looks awesome! Do we need something like this for the Acorn Electron? 🤔

Electroniq now supports importing text files (e.g. BBC BASIC programs) via "turbo pasting". It also supports exporting BBC BASIC programs to text files, for easy editing in your favourite editor. Try it at 0xc0de6502.github.io/electroniq/

I want my Acorn Electron emulator Electroniq to be able to import/export BBC BASIC programs in regular text format. However, tokenising BBC BASIC is not exactly a trivial task. So I am experimenting with this alternative method: turbo paste! This is working remarkably well, even for large programs 😎

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...

With the libretro core version of Electroniq, I can finally easily load and play Acorn Electron games on my Android device (via RetroArch) using the touchscreen! 😎

I think I'm going to have some fun with this! Many thanks to rax (x.com/oric_rax)

So now I have 3 separate 64bit libretro (RetroArch) core versions of Electroniq, running all at once on Windows 11 in this video. Windows core on the left, Linux core (via WSL2) topright, and Android core (via BlueStacks) bottomright. Investigating touchscreen input on Android version now...

While Commodore just got revived, Microsoft released the source code for Microsoft BASIC as used in the Commodore PET and others under the MIT open source license! opensource.microsoft.com/blog/2025/09... #8bit #mos6502 @wearecommodore.bsky.social

Getting keyboard and audio working in the amd64 libretro core version of Electroniq went smoother than expected. Here is Flappy Bird in RetroArch with the Mega Bezel Amber shader 😎

Very first result with compiling Electroniq (Acorn Electron emulator) as a libretro core for e.g. RetroArch. This opens up possibilities such as using many cool shaders, like this CRT effect. Next up: keyboard input and sound output 👾🕹️

Well done Chris!

I'm pleased to announce the #Elite Compendium for the #Acorn #Electron, containing three amazing hacked versions of Elite on one disc. It includes a brand new version: musical Elite. On the Electron! Lots of details here: elite.bbcelite.com/hacks/elite_... #retrogaming #retrocomputing #bbcmicro

With only about 2 days left, I couldn't help myself but make a pledge to the Spectrum Next kickstarter for an upgrade board 🫣

This man speaks truth, thanks Colin! 🥰

Electroniq update. More reliable 50fps. Improved accuracy. Analogue/digital joysticks support, e.g. DS4Windows + PS4 controller. Load plus1.rom or ap6.rom for analogue joysticks. Added more quickplay ROMs (games) thanks to Nyimski 0xc0de6502.github.io/electroniq/
