Unless you are able to catch that Pokemon in that place with that level in regular X/Y, it will probably be rejected in online play. Example: A Patrat caught at Kalos Route 2 will most likely be rejected, because it is not a valid location for a Patrat to be caught at. (However if you breed that Pokemon, the resulting Egg should be legit.)Thanks. However, my version of the game only edits the story and the trainer changes. The pokemon will be unedited. You think that would be satisfactory to play online with? Otherwise I'd have to play Neo Y, then Star Sapphire (another hack) and then either normal X or normal Ruby to actually play legit.
@Flintiex I noticed that Blaziken and its pre-evolutions do not have a chance to get their Mega Stone, is that intentional? I'll update the Pokemon Changes document tomorrow to reflect the changes of 1.32.
