Windows

Version

v0.1.0-alpha.1 (pre-release), Oct 18, 2026

Completeness

Partly Playable - “Complete two-PC matches and the full DLC/stage roster have not been comprehensively verified.”

Decomp Buddy never downloads games. It sets up WindowSmash 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.
