My switch has been acting dumb for a long time, so my brother replaced the SD card.
It fixed the issues, but I'm sure you can imagine what happened to all the saves.
When I was a kid I got all the way to Yunalesca on Final Fantasy X and went over to my friends house to play. We stopped playing my save and started playing his and he was on Sin left/right fin. Then we accidentally SAVED OVER MY FILE...... I didn't have the willpower to play it all over again and I def didn't want to start from where he was (he was a bit further and had completely different gear and stuff)

All of them.
