Any way to edit a Mon brought forward without home

[zorca13]

Title may not make sense, but what I’m wondering is, is there a way to edit a mon from an older gen so that it’s still legal? Prime example I have my original saves from gen 3 and 4, especially with starters being in indigo disk, can I bring them over through the “trade simulation” of using two pkhex windows, or even just copy/paste the pkm files and that’s all it is? Thought I’d ask with the new info that Nintendo is shutting down the old online for 3ds

If you want legal Pokemon, you have to legitimately transfer them through HOME in order to get a valid HOME tracker.
