Mac PC is now common around the world, and it’s not surprising that some people would want to play game with it. It is for most titles, the only way to play Model 2 games.
There is support for increasing the internal resolution, force feedback and GPU hardware acceleration. Model 2 Emulator, formerly Nebula Model 2, is a Sega Model 2 arcade emulator for Windows, developed by ElSemi. BUT when I tried to play SpongeBob Yellow Avenger for the Nintendo DS (psp version doesn't work) the very first part of the game requires the touch pad (of nintendo ds). So my setup is OpenEmu v2.2.1 (on my mac 10.15.4) - I use my ps4 controller for everything and everything runs smoothly.
Like if you have an Windows PC emulator, or the iOS one, you can run Windows or iOS appliactions on your Mac computer, especially good for app developers. This in turn helps people to run different apllications exclusively for various OS on a single platform. It typically helps one OS to behave as another for as much amount of time as we want and then switch back to our original OS.
Emulator is the software that helps us to run multiple OS on a single hardware.
