Hidden generic NES emulator in Animal Crossing

Apparently, the NES emulator in Animal Crossing for Game Cube can run arbitrary ROMs on the same memory card as your town in addition to just the built-in games. Article about it here.

I was able to play Nova the Squirrel on it perfectly fine, though I'm not sure I like Nintendo's NES palette choice that much. I'd be curious to see what emulator tests the built-in emulator passes or fails.

If anyone else would like to try and play with this, there's a Python converter here and a GUI Windows version here.

Universal code for the NES item:

GameCube Memory Card Manager, a Wii homebrew app that makes it very easy to get the converted ROMs onto an actual memory card.

Nice! and here I first thought you were using whatever method that Rachel used to put Electronic Sweet-N-Fun Fortune Teller into Animal Crossing.

In my opinion this is a lot cooler than just replacing a game, because the game of your choice is actually in your town. Not in a hacked copy of Animal Crossing, in your town, legitimately playable.

If you execute arbitrary code, will Mr. Resetti yell at you?
