Hello. I'm playing Platinum. I already have a TID/SID for it. I know that you need to start a new game to get a new TID/SID. I was wondering if it is possible to change the TID/SID using PkHex? Normally, I would be against this but I really don't want to start all over just to get a new TID/SID. I already have a perfect Bold/Timid Shiny spread to obtain Uxie, Mespirit, Regice, Heatran, Manaphy, Cresselia, Darkrai, Dialga, Palkia, Shaymin, the bird trio.
I would like a TID/SID to get shiny 5IV Adamant Regirock or Regigigas (Jolly is an option), 5IV Shiny Careful/Impish Registeel, 5IV Adamant/Naughty Giratina, and 5IV/6IV Naive Azelf or Arceus.
If it is possible, how can it be done with PkHex?
