Im sure in the Jap version, all Legendaries come back after you killed them if you beat the Elite 4. I remember this was the case for Latias and Latios at least
i cant seem to go to the place where i can meet all the ppl i have friends codes with anymore... i always get the blue screen telling me the game has to be reset, but when i go to the wifi thing on the left side (the plaza) i can do it. kinda weird
in the jap version i caught a shiny geodude in the first cave to get to the second badge. then i caught a shiny magicarp at the dragon's den.
i thought i was the man xD
havent even gotten my first badge yet. my chikorita just became a bayleef and ive got no other pokemon
