I finally got around to creating a simple static website with most of my free games and tools. Play my games online by clicking on the game's image, or visit the corresponding GitHub page. It also lists most of the places you may find me online 😎 0xc0de6502.github.io

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

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 😎

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...

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.

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! 😎

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...

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 👾🕹️
