My Little Pony: Friendship is Magic - 8-bit Gamer Luna - Blow it

The universal cartridge technique. Failure to load, glitchy graphics, garbled sound, bad anything-it can fix all of those.

Fun fact-I have my N64 on my desk right beside me and mere hours ago, I had used this hallowed method to boot up Majora's Mask.
