Something Old. Something New

A quick overview of my talk at the first Impromptu, on what happens when you aim AI at old hardware.

A MegaWord cartridge labelled "MD Gold Build V1.0" seated in a black Sega Mega Drive, with red power lights glowing beneath the SEGA badge.

This is a recap of my talk at the first Impromptu, a creative AI lunch-and-learn I co-host in Belfast.

I’ll own up to something. I co-host an AI event, and I spent most of my slot talking about a processor from 1979 and a games console from the late 1980s.

It did involve AI, I promise.

Pointing AI Backwards

A lot of the energy around AI is pushing forward. New tools, new products, new workflows, new businesses. That’s where I spend my working hours.

But I’m just as interested in the other direction. What happens if you take all this new capability and point it backwards, at old hardware, old formats and old constraints that were never designed with any of it in mind?

For me, that meant finally making a game for the Sega Mega Drive, the console that made me want to be a game developer as a kid.

What I Covered

  • Slimeball Slayer, my first attempt, where I threw free assets at AI and hoped for the best. It was completely the wrong approach.
  • MegaWord, my Wordle demake, built between March and June and shipped as version 1.0.
  • Designing for 320 × 224 pixels and a palette of 512 colours, only around 61 of which can be on screen at once.
  • The background pipeline, and the custom tools I built to stop AI-generated art turning to mud.
  • An AI that plays the game and reports back on the bugs it finds.
  • Online leaderboards for an offline console, where the player becomes the network connection.
  • Respect for the developers who did all of this for a living, with no AI, no SDK and no internet.
  • The joy of finished things. A cartridge ships, and at some point somebody has to decide it’s done.

See the Slides

The whole deck is online. It runs in the browser, and it’s best on a laptop: use the arrow keys to step through it.

A "Full disclosure" slide in three columns: co-hosts an AI event, turns up to talk about a processor from 1979, and developing for hardware from the 1980s. A slide titled "Creating a 90's vibe" showing eight MegaWord screens at their native resolution. A slide titled "The background pipeline" listing eight steps from ChatGPT Image 2.0 to in-game, beside grids of Mega Drive palette colours. A slide reading "Respect. For the developers who did this for a living. No AI. No SDK. No internet. No forums."

If you want to go deeper, I’ve written about building MegaWord and connecting a Mega Drive to the internet without connecting it to the internet.

Thanks to everyone who came along. Details of future sessions will be on impromptu.info.
