Accuracy takes power: one man's 3GHz quest to build a perfect SNES emulator

It doesn’t take much raw power to play Nintendo or SNES games on a modern PC; emulators could do it in the 1990s with a mere 25MHz of processing power. But emulating those old consoles accurately —well, that’s another challenge entirely; accurate emulators may need up to 3GHz of power to faithfully recreate aging tech.
