Best on a computer

This is a browser version of the 1987 Amiga and arcade shooter. You fly a fighter up a scrolling map of fortresses and water, shooting ground targets and planes. Tab switches between the remastered art and the original pixels. There are five difficulty levels, two-player play, a CRT look and level warps.

How the creator made it

The creator gave Claude Code with Opus 5.5 the old source, a disk image and unfinished ports and asked for a faithful browser remaster. Claude translated the rules from the original 68000 assembly, extracted the maps from disk and ran image models on the original pixels. The creator playtested the builds and had the backgrounds regenerated with GPT Image 2.5 Flare when objects drifted off their tiles. The remaster used masks to preserve palette-based animation, and the creator kept the original explosion sound after comparing it with generated candidates.

The prompt

I want to create a modern version, webgl, playable in the browser. Faithful to the original but with AI-remastered art and sound.

This is part of the prompt; the creator didn't share all of it.
