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
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! 🤣

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

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 😎
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...

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? 🤔
