Copyable commands for repeatable launches.

Install Toolkit

cd RipperMoonToolKit
./install.zsh

Start And Stop Steam

gptk-steam --log
gptk-steam --kill

Install Steam Without Launching It

Use this during setup so Steam is validated and then closed instead of opening the Steam UI.

gptk-steam --install-only --install "$GPTK_EXTERNAL_ROOT/Installers/SteamSetup.exe"

Start Steam Install In Background

Use this app-style setup command so users can set paths and cover art while Steam installs.

./install.zsh --install-steam-background

Install Spacewar / AppID 480

Run this once from the Steam prefix when a co-op Steamworks test path needs Spacewar initialized. Let Steam finish installing Spacewar, then close Spacewar before launching the game profile.

gptk-steam --log --install-spacewar

Run A Game

cd "$GPTK_EXTERNAL_ROOT/Games/MyGame"
gptk-launch --prefix MyGame -- ./MyGame.exe

Close A Game Without Closing Steam

gptk-launch --prefix Steam --no-log -- taskkill /IM eldenring.exe /F
