Do what they did with Zeraora and block the new pokemon from being traded to the games or add an new update to USUM that allows the new pokemon(although its very unlikely and they didnt do it for XY or SM)
Im having problems with this Feraligatr. It has come all the way from Emerald version. Ive dragged it from a file from gen 3 to gen 4 to gen 5 to gen 6 and finally to gen 7adding the legal ribbons it can get but PkHex gives me an error when I try to add the Gen 6 contest ribbons to it. I don't know why it would give me errors. Here is the Feraligatr file.
160 - Feraligatr - 2CF768FF7FAC.pk7
I remember during gen 6 people would change their Rotoms forms using pkhex and powersaves so that it could have all the special moves Rotom gets. Yeah Game Freak has really rubbish hack checks.?
