For Apple Game Porting Toolkit · macOS Apple Silicon

Reap the wine prefix.
Run Windows games clean on macOS.

A native macOS launcher built on Apple's Game Porting Toolkit. Stage your library, manage Wine prefixes, snapshot before every update, and never lose a save to a botched rollback again.

RipperMoonKit macOS launcher showing a Windows game library, Steam support, and game profiles

A toolkit, not another store.

Drop your games on an external drive, map them to Wine prefixes, and launch with the exact GPTK flags each title needs.

Update safeguards
Every toolkit update snapshots your prefix tree. One-click rollback if a runner breaks your save.
Mod stack manager
ModEngine 2, Seamless Coop, Randomizer — toggle layers, see the resolved load order.
Resolved commands
See the exact shell line you'd type. Copy it, debug it, ship it to a friend.
Drive mappings
Map S: X: I: to your external root. Your prefixes stay portable across machines.
Per-game profiles
winver, DLL overrides, MetalFX, AVX, esync — saved per game, never shared.
Clean uninstall
Remove the toolkit, the prefixes, or both. No ghost files left under ~/Library.

Field-tested.
