First installation

Choose the launcher for your computer, extract or install it, then open it.
Open Environment. Both Mac build targets need full Xcode and Metal components; iOS also needs its platform components. Prepare your Apple ID for the later device installation.
Import your own games and keys. On Mac, open Export and select macOS or iPhone / iPad. On Windows, choose the iPhone / iPad target and follow the launcher to build.
After a Mac export, play from the library. After an iPhone export, sign and install through the launcher and transfer its separate game resources. An IPA alone is not a completed game installation.

Updates and saves

The release app identifier changed to io.s2arm.*. Beta saves do not automatically migrate to the new app. Back up before updating, reinstalling or changing signing identities.
