lol yes it was a Shiny Modest Latias. And as far as i can tell it's just been cloned, not hacked (there's tons of them around, but they all seem legit).
Lucky u for getting Platinum, i need a new DS. DS-cartridge slot is knackered, so now it's basically a GBASP with wireless-chat options, and a couple of a buttons and a screen that have no use anymore.
