I don't see a thing about Trainer Cards. And no, IV's are always the same.ok go to the game mechanics page and click on shiny pokemon youll see what i mean
EDIT i was wondering when you catch one of the dogs when you migrate it to pearl do its ivs get better or are they still 0/1
Don't post fake answers. It can't delete your file.if you softreset it doesnt harm your game but if you turn it on and off it could delete your file
Hard-reseting (turning off the GBA) over and over again is bad for the battery and the system, but it won't hurt your game.
