So I wanted to share a story of my childhood with all of you. Around 2004/2005, I had a link cable and a brand new Pokemon Sapphire.
I tried to connect it with a copy of Pokemon Gold with a friend. We didn't knew it wasn't possible and it wasn't clear how to do it. I was smart enough to know that at least there were some limitation, like there were limitation between first and second gen.
So on sapphire I went in the "data exchange thing" (can't remember how it was called), and in Gold in the Time Machine.
It didn't worked obviusly.
So the day after that Pokemon Gold started to act strangly. At first, the player was freeze. I remember that my friend saved in the route above Vermillion City. He could rotate but not move.
Other minor glitches may had happened but I can't remember or I didn't noticed them, since the game wasn't mine and I was just a spectator.
After that the "CONTINUE" button disappeard and the cartdrige apparently lost his ability to save the game.
So... What do you think it triggered that?
It is possible that a deletion of every data could have fixed the issue?
Pokemon Sapphire never had any problem since then. The link cable didn't worked properly after that, but maybe that wasn't caused by this experiment.
I tried to look online but I couldn't find anyone experienced this...
