  • The game has six different strip-reveal backgrounds, and they’re stored in a custom RLE-based compressed format.

    Let’s look at how the decoder unpacks them into the ZX Spectrum’s screen bitmap.

  • Samantha Fox Strip Poker has a surprisingly accomplished two-channel music player for a card game — especially one that’s only really remembered for other reasons.

    Let’s take a look at how it works!

  • Samantha Fox Strip Poker. Yes, really. I didn’t buy this one - it appeared on a magazine cover tape somewhere along the way, as these things tended to do in the 80’s.

    The game itself is a surprisingly competent five-card draw poker engine with a strip-reveal gimmick bolted on. Under the hood there’s actually some interesting code worth poking around in.

  • The Hobbit draws a location graphic for some of the places you visit. The graphics are stored as compact bytecode. Here’s how I decoded that format and turned it into readable instructions for the disassembly.

  • Pheenix contains a surprising number of visual elements from the arcade game, especially given it’s only a 16K game.

    This article looks at the “transition effect” which I guess is a little like the ship going into hyperspace to move onto the next phase/ level.

  • I played this one quite late on, probably as a magazine cover tape. Strange too, as I’m a HUGE fan of the arcade version - and this is a fantastic conversion!

  • I did a thing!

    I don’t tend to do talks anymore, and certainly never about Skoolkit and disassembly! So this is very much a first for me.

  • Using the Phaser game framework to recreate the bonus duelling level from the ZX Spectrum game West Bank.

    The difficulty increases every level by making the time the bandits take to fire shorter and shorter. Here’s how I’ve done this.

  • Using the Phaser game framework to recreate the bonus duelling level from the ZX Spectrum game West Bank.

    This is the code which runs when the player shoots a bandit before they’ve drawn their weapon.
