ELI5: How do emulators work?
gpt
There's basically a program on your computer that "pretends" to be another computer. Say you're emulating an old games console on a modern windows PC. You give the emulator a game file written for the games console, but it has to process it and display the results with your computer, obviously. It does this by creating what's called an "abstraction layer" - basically, it reads what the game wanted the games console to do, and translates that to making your computer execute instructions that produce similar results.
