Completeness

Partly Playable - “This is an experimental prerelease with incomplete stage coverage.”

Decomp Buddy never downloads games. It sets up OpenSA2 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.
