Here it comes Captain Translator ! (inlges is english i think)
Hi, makes me happy to see people who speak Spanish in the forum, would be great to give us a place to debate in Spanish, since not everyone knows inlges and is super average. Also in the game we are a lot, and we will be more because of the little nintendo approach in the Latino community.
Regarding your issue, go to the game folder Pokemmo / Data / Srings in this place you can stick a client package in Spanish, I have the Fire network, I found the emerald, but will soon circulate.
Do not try to change the Room, that's not possible.
In short, still can not play the emerald in Spanish.
So i think he get help from him
