Rights holder / original work: Out Run (SEGA)
A port of the Master System version of SEGA's Out Run. It uses the Out Run name, its 15 stages, and its three tunes (Magical Sound Shower, Passing Breeze, Splash Wave) converted from the Master System; tracks, scenery, music and handling were taken from measurements of the Master System version with extraction tools. The page credits “Original game : Out Run © SEGA” and calls it a free, non-commercial fan port, not affiliated with SEGA, adding that Out Run is a trademark of SEGA. No source shows a licence from SEGA. (itch.io)

About Outrun 2026 (Amstrad CPC 6128)
An unofficial, non-commercial port of the Master System version of SEGA's Out Run to the Amstrad CPC 6128 (128K), on a single disk. The page lists all 15 stages and their forks with the original curves and hills, the three full-length tunes (Magical Sound Shower, Passing Breeze and Splash Wave), a horizon and roadside scenery for each stage, arrow signs before curves, traffic, crashes and spins, the starting sequence with the crowd and lights, extended time at each checkpoint, three difficulty levels (HARD uses the Master System handling) and a manual or automatic gearbox. Because the Master System road relies on the console's video hardware, the engine was rewritten for the CPC, and the tracks, scenery, music and car handling were measured on the Master System version rather than guessed; it runs in Mode 0 with double buffering at about 16 frames per second, and the music was converted from the Master System's SN76489 sound chip to the CPC's AY chip. The page says the game “was programmed entirely by an AI: Claude Opus 5.5 (Anthropic), using Claude Code”: Claude wrote the Z80 assembly engine, the extraction tools and the music conversion, while Michel Louvet directed the project, tested every build on an emulator and on real hardware, and reported what was wrong. A free download on itch.io: a disk image for a CPC 6128 or an emulator set to 128K, played with a joystick or the keyboard.
How it was built
Partially verifiedThe itch.io page says: “This game was programmed entirely by an AI: Claude Opus 5.5 (Anthropic), using Claude Code. I did not write a single line of assembly: I directed the project, tested every build on emulator and on real hardware, and reported what was wrong. Claude wrote the Z80 assembly engine, the extraction tools and the music conversion.” The credits list “Programming, tools, data and music conversion : Claude Opus 5.5 (Anthropic), via Claude Code” and “Project direction and testing : Michel Louvet”.
- ObservedIndie Retro News reports that not a single line of the Z80 code was written by a human and that the creator used Claude Opus 5.5 via Claude Code for the engine, the extraction utilities and the music conversion. — Indie Retro News
Directed and tested by Michel Louvet, with Claude Opus 5.5 in Claude Code writing the Z80 assembly engine, the tools that extract and measure data from the Master System version, and the music conversion from the SN76489 to the AY chip. Each build was tested on an emulator and on real hardware. Version 0.9.1 was the latest download on 7 Nov 2026.
