AvenellCY-1
Fiction

Avenell and the Cyclorama never existed. The hardware is real: specified, emulated and playable here.

The company, its people, dates, prices and sales are alternate-history fiction. On this site every in-universe statement sits under a red tally lamp. The machine is not invented: its specification, emulator, development tools and cartridges are real software, and every game picture is a frame a real cartridge drew.

Real cartridges

Museum

Every cartridge built for the Cyclorama so far, one card each. The ROM sizes and SHA-256 hashes are read from the project’s ROM manifest when this site is built, and each picture is a frame the cartridge drew in the emulator.

In the fiction: catalogue numbers and release dates

Card catalogue

Retail cartridges carry the catalogue number Avenell gave them; the developer-kit cartridges were never sold. The hashes let you check a ROM you build from the project’s source.

Emulator

The museum player already exists as the project’s museum build (npm run museum): one self-contained page that runs every cartridge in this catalogue, offline, with save states and gamepads.

The website version of the museum player is in progress. Until it arrives, ERG: NIGHTSIDE RUN plays in your browser on its own page, on the same emulator.
