Documentation

Three parts: notes on how GrogVM is built, the reverse-engineered SCUMM v5 reference it is built against, and the method the work is done by.

Status — in active development. The Secret of Monkey Island plays from boot all the way to the end credits in a Chromium-based desktop browser — all four parts — with verbs, inventory, dialogue, cutscenes, saves, digital sound effects and CD-audio music, and every resource in its files is browsable in the explorer. Still ahead: OPL2 synthesis for the few AdLib-only effects, Monkey Island 2, and visual polish.

Engine notes

How GrogVM itself is built — the as-built architecture and the runtime subsystems that hang off it (the game loop, room transitions, camera, pathfinding, costume loading, audio timing, game identity, and the test harness).

SCUMM v5 reference

How the original SCUMM v5 engine and its file formats work, reverse-engineered from real game data — resources and the VM, rooms and graphics, actors and text, and the rules of interaction, flow, and timing.

How the work gets done

GrogVM is built by a human and an AI agent in tight, reviewed loops; these pages document that working method — and double as the agent's own briefing.
