I’m just trying to get my head around how Mono is used. Did they make a compiler that runs on the switch? Or is it a MonoGame dev that has got it working another way? Or has Nintendo already included Mono?
I’ve never worked with consoles, but to my knowledge, .NET IL is passed through BRUTE to generate native code for the Switch. Many consoles do not have a .NET or Mono runtime available.
EDIT: If you’re asking specifically about MonoGame, then yes it does; several games have been developed with it for Switch.
