I'm sorry to say I have to pause my "Wanted: Monty Mole" conversion for the Acorn Electron. I was unable to come to an agreement with the IP holder. I'd like to pick it back up if circumstances change. Auf Wiedersehen for now, dear Monty!

I took some time to make sure all tiles (and their specific properties) are correct for all 21 rooms in my conversion of Wanted: Monty Mole from ZX Spectrum to Acorn Electron... sharing this pretty picture for those who may attempt their own conversion of this classic game in the future 😎

"Wanted: Monty Mole" (WIP) on Acorn Electron. Took longer than expected because movement code is quite convoluted. Not perfect yet. Slowed down to target 25fps. Funny quirks in original game (and in mine): 1. No eye when walking right, 2. Walks slower on some tiles because constantly "falling"

A random thought that's been on my mind lately. Am I destined to be that stubborn old man still driving a horse and cart while everyone else is driving cars?

Wanted: Monty Mole (WIP) on Acorn Electron. When porting a game, I always seem to begin with the graphics (loading screen, sprites, tiles, etc). At least that way I get something on the screen as soon as possible, which boosts my motivation to continue with the rest of the conversion! 💪😎

Confirmed working on a real Acorn Electron (see photo)! 😌 However, there seems to be a 4 pixel offset between a real Elk and Electroniq, i.e. an improvement opportunity for my emulator! 🧐

Exploiting RAM contention to sync to hblank after RTC interrupt fires to get stable horizontal colour palette switching in MODE1 on Acorn Electron (from SWRAM). Video reveals the exact locations of the palette switches, including partial colour changes. Bit afraid to test on real hardware 🫣

2221

0xC0DE @0xc0de.bsky.social · 30/08/2026

This proves vertical colour palette splitting in MODE1 (!) is working on the Acorn Electron from SWRAM, but this is in my *emulator* and of course I need to confirm on real hardware. Also, I need to stabilise it a bit more... very happy with the proof of concept so far 😎 This has never been done!

0xC0DE @0xc0de.bsky.social · 30/08/2026

This is more like what I really want. I wish I could make a vertical colour split in MODE1 (but the CPU is stalled during the active part of scanlines on an Electron)... but wait a minute, not when that code runs from SWRAM (with interrupts disabled) 🧐🤯 To boldly go..............

Wanted: Monty Mole WIP (Elk48). Fixed Speccy colour clash issues and many small details. Then I had to make some tough choices about reducing the total number of colours from 8 to 5

Old school and humble beginnings (just the way I like it!). When a bit of BBC BASIC is just fine to convert the byte order of software sprites (Sinclair to Acorn). (No AI was harmed during this process)

Pyjamarama conversion for Acorn Electron 48K (WIP). With about 200 free bytes left, my conversion is 98% done. I only need to add sound effects, the title screen tune, maybe some alternate control keys and playtest on different emulators and a real Elk. Used every trick to cram it in!

ASCII Invaders (10-liner), an exercise in BBC BASIC code golfing. I enjoyed making stuff like this and should return to it one day. Inspect/edit the source code and play the game (Z,X,RETURN) via Owlet BBC BASIC Editor bbcmic.ro#%7B%22v%22%3...

0xC0DE @0xc0de.bsky.social · 23/07/2026

Pyjamarama (WIP). Demo mode done. Next up: fireworks on the "win screen". For these 2 features I unpack and hide the data (scripts) in the upper part of the screen temporarily. Desperate times, desperate measures when it comes to available RAM 😅

0xC0DE @0xc0de.bsky.social · 22/07/2026

I just fully realised that I'm porting a game (Pyjamarama) to a machine (Acorn Electron 48K) that has ~10K less *available* RAM than the original machine (ZX Spectrum 48K). No wonder I have to pull out all the stops to make it fit! (I love the challenge though 🧐)

0xC0DE @0xc0de.bsky.social · 21/07/2026

Pyjamarama (WIP). That's the Arcade Room (mini game) done! However, I may just rewrite this particular room in MODE4. That might give me a fighting chance for more speed and flicker-free sprites. At the moment the poor Elk is drawing twice the amount of sprite data as the Speccy 😫

Pyjamarama WIP. Slowly whittling down my "conversion to do list" (image shows tiny part of it). Major components left to convert from Speccy Z80 to Elk 6502: arcade room (mini game), demo mode, celebratory fireworks, sounds & tune, and maybe key redefinition and joystick support 🥵

0xC0DE @0xc0de.bsky.social · 14/07/2026

Haha, pesky gotcha (circular interdependency issue)! Uncompressed data (fixed size) contains absolute addresses. Compressed data (variable size!!) is INCBIN'd in source, causing some absolute addresses to change. Hence making the absolute addresses in your compressed data incorrect at runtime! 🤯😱

Pyjamarama (WIP). On a scavenger hunt for preciousss RAM! Fortunately this Speccy game isn't particularly tightly packed so I see plenty of options. I am going to pack all room and furniture data (from 4626 to 2168 bytes) and unpack it to (hidden) screen RAM right before drawing a room

Port of Pyjamarama to Acorn Electron (WIP). I have converted enough to be able to complete the game now. Working on the "you lose" and the "you win" screens, with nice chunky font. Screen mode split is still active but you won't notice it. Also, large boulder could be smoother but is good enough

Pyjamarama (WIP). Sacrificing some of my beloved precalculated tables because I am getting desperate for RAM (and don't want to add a second 16K RAM bank). The elegance of the hybrid replacement 6502 code (calculate screen address given X,Y) is still *chef's kiss*

Port of Pyjamarama to Acorn Electron (WIP). In the end I had to create a fake ZX Spectrum "attribute map" (but 768 bits instead of 768 bytes) to test for solid or non-solid tiles and have Wally move *exactly* like he does on the Speccy
