How I Wrote an Retro 80s-Inspired Adventure Game About The KLF

If you grew up in the 1980s, you’ll remember that unmistakable feeling of loading a game on your ZX Spectrum, Commodore 64, or BBC Micro. The hypnotic screech of the cassette loading, the colour bars flickering on screen, and that eternal moment of suspense — would it load this time, or had the tape stretched just enough to doom you to a R Tape Loading Error?

Fast forward to the 2020s and, somewhere between my love of retro computing, The KLF’s music, and an itch to make something creative, I decided: I’m going to write a text adventure game. Not just any text adventure, but one dripping with late-night 80s energy, pop culture references, and a healthy dose of KLF mythology.

It started innocently enough — I wanted to relive the magic of the Scott Adams-style adventures I played as a kid. Those games weren’t about graphics; they were about imagination. Every location, every object, every strange instruction was something you had to picture in your head. And if you were a bit obsessive (guilty), you’d spend hours mapping every room on graph paper.

Finding the Right Ingredients

The KLF have always been masters of mystery — their story threads through pop hits, art projects, strange performances, and burning a million pounds on a remote Scottish island. That mix of chaos, humour, and myth-making was perfect for a game world.

I started building a map: fictional places merged with real ones from KLF history. Bold Street in Liverpool. The Cavern Club in the 1960s. A boathouse with a roaring fire. And, naturally, Trancentral — the spiritual HQ of The KLF. I even included surreal locations like the “Little Fluffy Cloud Factory” and “Maze of Caves” for that dreamlike adventure feel.

The NPCs? Oh, they had to be special. Sigmund Freud gives cryptic instructions. Ivan Pavlov demands you “Lie Down” before telling you to “Keep Calm”. Even Denzil the Baker makes an appearance, along with other nods that KLF fans will appreciate.

Building It Like It’s 1984 — With a 2025 Twist

I didn’t just want to write about the 80s — I wanted it to feel like the 80s. So I coded the game in a modern environment but kept the old-school constraints: short descriptions, tight vocabulary, and a parser that understands commands like GO NORTH, GET TICKET, or SAY CHILLOUT.

But here’s the twist — I didn’t do it alone. My coding partners were Gemini CLI and OpenAI Codex, coding with me directly in my command line. The imagery was created using ChatGPT, with animations by Midjourney. The music came courtesy of Suno, while the sound effects were crafted by ElevenLabs. Together, these AI tools became my team of coders, designers, composers, and consultants, enabling me to bring this game to life in a way that would have been impossible on my own.

And because I couldn’t resist going full retro, I’ve also been experimenting with encoding the game into audio so it can be loaded into a ZX Spectrum emulator straight from a physical cassette tape. Because why not?

The Result

What emerged is The KLF Adventure — part game, part interactive art piece, and part love letter to the days when imagination did the heavy lifting. It’s an 80s-inspired world you can explore, puzzle over, and get gloriously lost in. It rewards curiosity, nods knowingly to KLF lore, and might just make you say “What Time Is Love?” at least once.

For me, this wasn’t just a coding project. It was a way of reconnecting with that kid who sat cross-legged in front of a rubber-keyed Spectrum, waiting for the next adventure to begin. Only now, I’m the one writing the adventure — with a 21st-century team of AIs by my side.

You can even find me in the game... But where?

Gadget Man Episode 144 – Retro Gadget of the Week – Part 9 – 80s Home Computers

In our penultimate episode of Retro Gadget of the Week, we take a look at one the most revolutionary moments in computer history,  where an explosion of homegrown talent changed the very face of the personal computer marketplace and faced up directly the power of Silicon Valley with low-cost home computers designed in the UK

Commodore VIC20 Personal Computer
Commodore VIC20 Personal Computer, my first computer in all it’s 3.5k glory and 22 columns display

I was very lucky to receive a Commodore VIC20 personal computer for one of my birthdays in the 80s and proceeded to embrace coding head-on! Unlike other home computers, the VIC20 only supported it’s own tape drive, so instead of using our portable cassette play like my mates with Sinclair ZX Spectrums, I had to wait until I save enough money to buy my own Commodore Datasette.  This meant that every single program I wrote on the Vic was lost when the power was switched off, I either needed to write down my code or memorise it!

Alongside the American VIC20, a slew of other devices was released by UK based companies. The most famous was the Sinclair ZX Spectrum and ZX81. However, other notable UK made systems included the BBC Model B (built by Acorn), Dragon 32Amstrad CPC464, Apricot F1, Camputers Lynx, Gundy Newbrain, Jupiter Ace, Memotech MTX, Tangerine Oric 1 and many others.

Dragon 32
The Dragon 32 used the Motorola 6809 CPU

Almost all home computers of the era were based on the Zilog Z80 or MOS 6502 microprocessors with a small number going with the Motorola 6809 (which was more advanced that the Zilog and MOS processors).

The computers were generally self-contained devices, combining keyboards and computers as one with connectivity with colour or black and white TV’s which the user was generally expected to supply. Other peripherals were available such as tape drives, floppy disk drives, printers, joysticks and light-pens. Some models also supported plug-in cartridges which generally allowed the owner to play pre-programmed games.

Sinclair ZX Spectrum 16K 48K
The Sinclair ZX Spectrum 48K was the darling of the 80s market due to it’s price and range of games

The first to the market came with minute amounts of programmable RAM in the region of 1K to 5K, later entrants from the UK market settings with 16K or 32K with some stretching even further.  If I compare this to my Sony Xperia 1 mobile that I use today, this comes with 6 Gigabytes of RAM which is roughly 1,700,000 times more than my Commodore VIC!

Commodore 64 Personal Computer

BASIC Code - Beginner's All-Purpose Symbolic Instruction Code

Almost every computer came preloaded the BASIC (Beginner’s All-Purpose Symbolic Instruction Code) programming language which allowed a new breed of programmers to begin crafting their own code. Although the basics of each version of BASIC remained similar, that’s where it ended, different hardware and firmware made each machine incompatible with the other. Having a market saturated with different devices which didn’t speak the same dialect was the architect of their demise.

BBC Micro Model B
The BBC Micro Model B, built by Acorn as a joint venture with BBC. It found it’s way into schools as the staple computer for education.

After 3 to 4 years, the majority of these computers had become obsolete and fell out of use leaving the BBC Model B surviving through use in UK schools, colleges and universities and the Commodore 64 which had become a glorified games console rather than a way for young people to gain computer experience.

IBM PC AT
The IBM_PC_AT and it’s lower cost clones swooped in and stole the market

Along came affordable IBM PC clones from Dell, Compaq, AST and Gateway which WERE compatible with each other. Users began migrating across to these PC compatibles and the market was replaced at home and office. It was the end of an era.

Without the likes of Commodore or Acorn, my life would have been very different, so I have to tip my hat to the 80s Home Computer!.
