Bubble Ghost Floats Onto the Amstrad CPC 6128

Some games are simple on paper and nerve-wracking in practice. Bubble Ghost is one of them. The 1990 Game Boy puzzler now has a new home on the Amstrad CPC 6128, thanks to a fan conversion from developer Kirby2000.

It's a fitting release for the spooky season, too. A haunted fortress, a friendly spirit and a very fragile soap bubble make a strange but charming combination, and that combination is now playable on the 8-bit home computer.

Blow Gently, Little Ghost

The premise hasn't changed. You play a helpful ghost whose job is to guide a soap bubble through the chambers of a haunted fortress. There are 35 of them, and none of them are friendly.

The catch is that the ghost can't actually touch the bubble. Any contact and it's over. Instead, you have to blow it forward, nudging it along with careful puffs of air. It sounds easy until you're trying to squeeze that bubble past something sharp.

And there is plenty of sharp stuff. Spikes line the rooms, fans push things around in ways you don't always want, and rival phantoms get in the way. Candles also need to be snuffed out along the route, which adds another layer of planning to each screen.

On top of all that, every level has a bonus timer counting down. So you're balancing patience against speed the whole way through. That tension has always been the heart of Bubble Ghost, and it's good to see it carried over intact.

A Faithful Recreation

Kirby2000 has clearly taken the source material seriously. The conversion includes all 35 of the original stages, and every puzzle mechanism from the Game Boy version is reportedly present. The full ending sequence is in there as well, so anyone who makes it through the fortress gets the proper payoff.

The visuals lean into the game's handheld roots rather than trying to reinvent them. The graphics are styled after the Game Boy original and sit inside a custom themed frame around the play area. It's a nice touch that makes the whole thing feel like a deliberate tribute rather than a rough port.

Before you even start, there's a loading screen adapted from the original retail box art. Little details like that matter to retro fans, and I suspect a lot of CPC owners will smile when it pops up.

Chip Music and Clever Loading

Sound gets the same attention. The classic soundtrack and the retro sound effects have been recreated using the Amstrad's internal AY audio chip. That's the machine's built-in sound hardware, so there's no extra kit needed to hear the music.

Loading is flexible as well. The game works from an original 3-inch floppy disk drive, the odd-sized disks the CPC 6128 was known for. It also runs from a Gotek drive or an M4 SD card adapter, two modern options many CPC users rely on today.

Whichever method you use, the game loads fully into memory at the start. After that, it never touches the disk again during play. For anyone running real hardware with aging drives, that's a welcome bit of design.

A Note on AI

The release carries an AI disclosure, stating that AI assistance was used for the code. It's worth flagging for readers who care about how these projects are made. It isn't the first time this has come up in the CPC scene, either. The AI-coded Outrun port landed on the same platform only days ago.

Our Take

Bubble Ghost is a small release, but it fits a pattern we keep seeing. Fans are pulling games from other platforms and rebuilding them for machines that never got them. Only last week, HAL's 1984 MSX pinball game arrived on the Amstrad, and the Commodore 64 just received a DOOM64 demake. The CPC scene in particular seems to be having a very busy autumn.

What stands out here is the focus on completeness. All 35 stages, the full ending and support for both old and new storage hardware suggest a project aimed at real players, not just a quick experiment.

The AI disclosure is the other thread worth following. Two AI-assisted CPC releases in one week suggests these tools are finding a place in the homebrew scene. It is worth watching how the community responds, and whether more developers start labelling their projects this openly.
