From my N64 days of my childhood, there's one particular thing I remember. It was from Pokemon Snap.
I wanted to play it one day, so I put it in the N64 and started up the game. When I went to continue, Oak appeared in his lab and said "Sorry!" in a recording to tell me an error occurred with my save data. As a kid, this scared me.
I can't find anything else on this anywhere on the internet. Has this ever happened to anyone else?
