Oh yeah I dont know the pRNG method of black and now that I think about it you can just do normal rng enter your SID and click on search for nearby shiny frames or something like that. That way you can get good ivs and a shiny pokemon. :)
Ohh yeah do you have AR codes for B/W if so can you ev train one of my pokes via vitamins and wings if you do you can keep a copy of the poke you ev train?
