If you want to play an N64 game on your PC, you’ve almost certainly used an emulator at some point. Project64, mupen64plus, or maybe the N64 core in RetroArch. You drop in a ROM, the emulator reproduces the N64’s CPU, graphics, audio, and coprocessor behavior well enough for the game to run, and it just works. It’s been the standard approach for decades, and for most people, it’s still the obvious one.
