Completeness

Mostly Playable - “Nebula is a work in progress. The game is playable from the start, but some areas run below”

Decomp Buddy never downloads games. It sets up Nebula and tells you exactly which file of yours to drop in - then checks it's the right one. A ready-made plan is published for this one, so no AI key is needed.
