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.

The cartridge · in the fiction

Avenell Playhouse's Christmas 1988 title: Erg, with a helmet lamp and lime work gloves, fights the five house champions of the Turning Cup in a dark ring hall. Before a champion strikes, the lamps swing a pool of light onto the lane he means to hit; flare into his face at the last moment to dazzle him.

How to play

After the Curtain Up splash, press Start (keyboard Enter, or a controller's Start button) on the title screen and again on the how-to-play page. Each of the five bouts opens with a card, then Erg stands in one of three lanes at the bottom of the ring, seen from behind. Slip one lane left or right with the D-pad (arrow keys, or a controller's d-pad or left stick) and hop with Up. A or C (keyboard Z or C) jabs; B (keyboard X) flares your helmet lamp and costs one lamp cell. Before every strike the ring lamps swing a pool of light onto the lane the champion means to hit: a round pool is a straight punch on one lane, a square pool covers two lanes, a band across the whole floor is a sweep. It swells and brightens until the strike lands, so slip out of it or, for a sweep, hop it. Jabs only land while the champion is open, which is after a strike has missed; a jab thrown at any other moment bounces off his guard and locks your hand for a moment. To do better than dodge, stand in the light and press B in the ten frames before the strike lands: the flare hits his eyes, the strike fails, he is dazzled and stays open a long time, your jabs count double, and your lamp gets two cells back for the one it cost. A flare with nothing to catch is wasted, a sweep cannot be dazzled, and a feint swings the lamp without a real wind-up. A champion's level is his own spotlight: it dims as you hurt him, and when it goes out you win the bout. Each strike that lands costs two or three lamp cells; with no cells left the lamp goes out, you lose one of your three lives and the bout starts again. Start pauses. After GAME OVER press Start to go back to the title; the win screen stays until the console is reset.

What is running

When you power on, your browser runs an emulator of the Cyclorama: its CPU, its video chip with the light field, and its Cue sound chip, at the real frame rate. The cartridge is the same 256 KiB ROM the project builds and tests, byte for byte.
