Most problem those give tend to be turn it on and it says, "hey I'm not so sure you put a game in me, would love to play one for you, though!" Or "I think this might be a game or it might just be a weird blue pattern because the connection is there but only partially".

At least the NES was like that. You had to know the ritual to put the cartridge in correctly and that ritual changed. I don't ever remember having a ritual with my N64.
