Plain answers for common questions.

Does RipperMoonKit include games or Apple GPTK?

No. You provide your own Apple Game Porting Toolkit download and your own game files. RipperMoonKit can install the prebuilt GPTK app runner through Homebrew when needed, but the Apple GPTK runtime still comes from the GPTK download you mount yourself. The repository only contains launch scripts, the app, examples, and documentation.

Should I copy installer files or an installed game folder?

For the tested Elden Ring workflow, copy the already-installed Windows game folder. Do not use only the installation files as the game source.

Can one external drive have several letters?

Yes. Several Wine drive letters can point to folders on the same physical drive. Keep C: reserved for the prefix.

Can I close the game without closing Steam?

Yes. Use the GUI's Close Game button. It targets the selected game process and leaves Steam running.

Why install Visual C++ runtime per prefix?

Wine prefixes behave like separate Windows environments. Installing the runtime into the prefix that launches the game avoids many runtime popups and early exits.

Why does source setup download SteamSetup but not always install Steam?

Downloading SteamSetup.exe is safe and repeatable. Installing Windows Steam creates or modifies the Steam prefix. The guided app setup starts Steam installation in the background, moves to the finished screen, and closes Steam after validation. The source installer only installs Steam when requested with ./install.zsh --install-steam.

Will updates delete saves?

Normal updates are designed to avoid saves, Wine prefixes, Steam data, games, and GPTK runtime folders. The installer backs up small toolkit files before replacing them.

Can I repackage or reuse the code in another launcher?

No. RipperMoonKit is free to run and source-available for personal use, inspection, private modification, and upstream contributions, but it is not licensed for repackaging, resale, rebranding, or embedding into another product. See the License page.
