S2Arm
S2Arm · Switch game builder and runtime
S2Arm builds on the approach pioneered by D2R Mobile. It rewrites 64-bit Switch game code for native ARM64 execution and translates graphics calls to Metal. Build your own games into a single app and launch them from its library on iPhone, iPad, or Apple silicon Mac. The Windows launcher builds and installs games for iPhone and iPad.
