*Sorry if this is in the wrong section or it had been made before, but I am just so frustrated*
Okay, without any introductions, I traded 3 legit Pokémon with my friend, and we decided we would return those Pokémon the day after. I had a PokeSav window opened before I got those 3 Pokémon. I plugged my flash cart into the computer, but then I accidentally clicked on "Save" on the older PokeSav screen, therefore, I lost my friend's Pokémon. When I opened the save file, they were, as I expected, gone!
How can I restore them? Please, someone, anyone, help me! =(
[i don't want my friend to know I use PokeSav, and I can't do his Pokemon on PokeSav, as I don't know anything about them]
