I’m not familiar with the way iOS apps are run on Big Sur natively. What happens when multi-touch with hand-eye coordination is required? My Mac runs a Nintendo DS emulator fine, but it sure is a bitch for a game like Scribblenauts, or any game requiring drawing precise shapes or letters - because the input was designed for a stylus, not a mouse or trackpad. Also; the distance between the input device (mouse) and the output appearing on a monitor in a different locations make playing a handful of DS games in an emulator an awful representation of the actual experience. While I get I can probably run Instagram or whatever, I’m just curious as to how they handle all these flaws with porting multi-touch heavy apps - a huge cornerstone of iOS devices. Just wondering how they handled that. :)
