Well, I found a copy of Pokemon SoulSilver at a yard sale this morning. I just had to have it since Silver was my first experience owning a Pokemon game. It was a Christmas gift I got with a GBC beck when it came out, and I logged a couple hundred hours on it before I stopped playing (kid was handing out hacked Celibi's on the school yard, which ended up resetting the flag for trading and I was unable to activate it again. I only had 6 more Pokemon to complete my Pokedex and I was so discouraged I stopped playing completely.
So, I got SS this morning and selected my starter, Flamey the Cyndaquil (my starter years ago). Grinded it to level 11 before my first Trainer battle, caught a couple of beginner Pokemon, went to save before training them and couldn't. Didn't delete the old save first.
I'm a dumbass and Flamey died (okay, being dramatic here) because of it.
