I was watching [this] and because i'm dumb I watched the video and did exactly what he did as he did. He told me to change the Pokemon backup (I think) file to a .txt file so I did, and I put my SD back into my DS. So later he say's in the video ''never leave the file as a .txt file, always put it back with .bin format BEFORE you put it in your DS'' O my god what did I do. by the way I backed up the original file as said and replaced the old one as I was told to in the video (It was a .bin file).
What did I do to my game?
(If possible) Has this any negative effects on my 3ds?
If this is banned fine but I don't think I broke any rules.
Edit: Ok guys just to let you know my game works perfectly, no errors whatsoever that I have seen so far. If your going to answer this give the effect AND a reason ''you just f** your game'' is terrible, seriously. HOW did I apparently F my game and why?
