Hi /vp/!
I have a question regarding gen 3 games trade and I hope someone knows the answer for it.
I've been trading Pokémon between a japanese Ruby and an american Emerald, and I realized that when the Pokémon arrives to the other version, for a fraction of second they blink in a purple color. At first I thought it had something to do with them being infected with pokérus or something, but it is not the case.
The pokémon are mostly legendary, don't know if it could be part of the reason why it's been happening.
What could it be? I tried searching about it, but I got no results.
Thanks in advance.
