ELI5: How does a Super Nintendo or Sega Genesis game get from cartridge to being emulated on my phone?
gpt
Basically, it's possible to design software that imitates (emulates) what the SNES or Sega Genesis hardware does. Since those machines came out in the early 90's, any computer today can easily handle running it. The software that was on the cartridges can just as easily be written onto your computer's hard disk and be loaded up by your virtual SNES/Genesis.
