However, the "best" NES86 experience can be achieved in a rather unexpected way – by playing the original Animal Crossing on GameCube emulation. Nintendo's 2001 social simulation game included a built-in NES emulator, allowing players to collect and play various NES games through in-game mechanics.
By hacking the NES emulator inside Animal Crossing – while running on a GameCube emulator – decrazyo managed to run the PC version of Tetris at a mind-numbing 30 seconds per frame. Yes, you read that correctly. Now, if you'll excuse me, I need to go dig out my ancient Italian-made IBM PC clone (Olivetti Prodest PC1) from my parents' garage and spend the night playing Lode Runner.
It's like that Inception movie.
