No Entry/No Result codes may be what you need to stop the freezing at the end of the match
added the codes, tried, and weird freezes occurs, the strange think is , if I select 1 snake and 1 charizard, 1 ivysaur, and 1 squirtle, start the fight, end the fight, and after that I select snake, pikachu, any pokemon of pokemon trainer, and zero suit samus , the game dont freeze after the end of the match and I can start and end that fight anytime with no freezes, but when I leave the CSS screen, go back, and just after that I start and end a fight between zero suit, snake, pikachu. and any pokemon of pokemon trainer, the freeze thing happen again...
