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/

Very cool! Also: Electrobots 2 meets Chuckulus vibes

I don't need a Next 3. I don't need a Next 3. I don't need a Next 3...

Perfection! 😍

For some time I thought my joystick support code in my Acorn Electron emulator (Electroniq) was not working properly. But I am now convinced, after testing with ancient analogue joysticks on a real Electron with a Plus 1 add-on, that actually joystick support in some games is just broken!?

New Acorn Electron demo effect. I am pretty sure this 50fps hardware scroll with *single* scanline precision has never been done on the humble Elk... until today! 💪😎 Remember, the Electron has no CRTC or other dedicated video chips

By exploiting CPU/ULA RAM contention it is relatively easy to have a stable raster for any part of the screen. The example in MODE4 also demonstrates that not all emulators are equally accurate. First image is correct (real Electron, Electroniq, Elkulator), 2nd is Clock Signal, 3rd is Electrem

Electroniq WIP. I'm a sucker for *detailed* information while debugging my Acorn Electron 6502 asm code. Visual indication of the electron beam? Check. Current PAL field, scanline and exact 2MHz cycle within that scanline? Say no more, I got you covered... and then some! 🤣

Me and @retrogamingpappa.bsky.social did a big interview with Peter Liepa, the creator of Boulder Dash. We could have shortened it a lot for readability's sake, but you never know what seemingly minor details future historians would want to see. So here it is:

Electroniq WIP. New feature now online: view RAM as pixels in any selected (or automatic) screen mode. It is a great way to see what is going on 'behind the scenes', in a hidden screen buffer for instance. Try it yourself at 0xc0de6502.github.io/electroniq/

I am working on speeding up #Elite on the #Acorn #Electron. It's going well. On the left is the original; on the right is my enhanced version. It's all down to sideways RAM and backporting faster code from the #BBCMicro and #C64 versions. More details in thread. (1/4) #retrocomputing #retrogaming

Electroniq WIP. New debugger feature coming soon. Jump from breakpoint to breakpoint or singlestep through your 6502 source code, all while drawing over the previous PAL field and showing the exact position of the 'electron beam' in the current PAL field (including hblank and vblank)

This is a great thread about the hardware and software being used to create the most epic version of Acorn Electron Elite by @markmoxon.bsky.social

Electroniq WIP. New and improved version online. Now handles anything a real Acorn Electron can (famous last words). If you don't get a stable 50fps (looking at you Firefox) please try a different browser (or system 😉). Any issues? Let me know here or on github... 0xc0de6502.github.io/electroniq/

Electroniq WIP. That's Southern Belle (and Evening Star) fixed (yes, they are slow games)! I tried to clear a tape interrupt using a bitwise-OR! 🤦 These were the last known(!) incompatibility issues I needed to fix in my Acorn Electron emulator. I guess I should put this version online soon 😎

Electroniq WIP. This was a pig to get 100% right in my emulator. FireTrack for the Acorn Electron is a technical marvel and a great test for emulator writers. I can now throw almost anything at Electroniq and it will just work like a real Electron 😎

Electroniq WIP. I can finally run one of my older Acorn Electron demos flawlessly in my emulator. So now a real Electron and Electroniq (next release) are the only 2 machines that can run my demo correctly 😎

Thanks @merman1974.bsky.social for publishing your entire interview with me on your blog! 👍

I was a bit sidetracked (ok, obsessed) with improving the accuracy of my Acorn Electron emulator. Compared with a real Electron of course. My tests show that the CPU now correctly switches between 0, 1 and 2MHz controlled by the ULA. Including cycle stretches when slowing down from 2MHz to 1MHz

Just a quick "unboxing" (not sure if that applies to a magazine!) of the Retro Gamer I received yesterday, including some ramblings about the Dune launch party, 20 years in Norway, and Michael Bay! 😅 www.youtube.com/watch?v=39Ph... Noticed that @0xc0de.bsky.social was also in the magazine!
