Rollerball never touched Amstrad hardware in 1984, and there was no obvious reason it ever would. HAL Laboratory, years before it became synonymous with Kirby, built the pinball table for MSX computers and left it there. Forty-two years on, a developer going by Oldschool is Beautiful has ported it to the CPC anyway, and the result runs on a 6128, or a 464 or 664 with a 128K expansion bolted on.
The interesting part isn’t that somebody ported an old pinball game. It’s how they went about it. Rather than approximate the original’s ball physics from scratch, the port reconstructs them directly, so the table plays the way the MSX version actually played rather than a CPC programmer’s best guess at it. The MSX’s native 256×192 resolution gets reproduced on CPC hardware through Mode 1 dithering, with a double-buffered display stopping the screen tearing that would otherwise show up mid-flipper. Bumpers, bonus lanes and the original scoring system all carry across intact, and the audio has been rearranged for the CPC’s AY-3-8912 sound chip rather than just dropped in unmodified.
That’s a proper conversion job, the kind that used to take a dedicated coder several months of evenings. The CPC homebrew scene has produced plenty of ports built on guesswork and “close enough”, and Rollerball CPC is clearly aiming past that bar.
One detail worth knowing before you credit a very patient programmer with all of it: Oldschool is Beautiful has been upfront that AI assistance went into the code, graphics, sound and text. How much of the physics reconstruction was hand-tuned against the original and how much came out of a prompt isn’t spelled out, and that’s worth bearing in mind alongside the technical write-up rather than instead of it.
Whatever the exact division of labour, the table itself is free, it’s on itch.io now, and it asks nothing more of you than a CPC with enough memory and the patience to load a tape or disk image. For a machine whose software library skews heavily toward text adventures and Arnold-branded curios, a competent pinball table with real bumper feel is worth the floppy space.
