Oh, sure. I have a powersave now so I can clone up several things in my own collection. Is there any pokes in particular you'd like to have on hand again? Message me back with a list, don't even worry if it's a bit long (I may not have half of what you really want back) and I'll clone up anything I have a copy of for you :) Don't be afraid to list events or even shinies. I don't have a whole lot of shinies, but I am willing to clone you up what I do if it's something you lost and want back :)
Also, not that it helps you out now, but you can back up your games with a powersave of your own. Might be helpful (and it actually also allows multiple people in one family to use the same game cartridge by backing up the save file for each person, deleting the game to start a new one for the new person, then back up their save file and you can just put the game cartridge in the powersave after that and download the backup for whomever wants to play, remembering to back it up with the powersave after each playsession).
