// D-J one is not clear that it was legit, only EUROPE. Notes from Suloku about D-J one:
//
// El caso es que al final apareció el verdadero mew que repartieron en madrid, OT EUROPE.
// Lo tenía un jugador que después de muchos años volvio a pokemon, y ya en la época tenía métodos de backup de
// partida en gameboy, incluso estaba registrado en un foro de la época (inglés) donde había mensaje suyos
// hablando de ir al torneo etc, todo verificado así que en principio ese mew es el que realmente repartieron.
// El mew D-J...sigo pensando que efectivamente rondaba por madrid en el parque de atracciones, pero "repartido"
// a base de clonaciones. O quien sabe, puede que alguien cambiara su mew hack al repartidor oficial del evento
// y este se lo diera a otro jugador al ver que era un mew.
