Crash with Pokemon White 2

[NicoRobin4]

Hi everyone, I'm new here, well i just dowloaded Pokemon White 2 and I started to play, there was no problem on the first 6 gyms, but when I came to a city (cant remember the name, but in this place you, Bel and the profesor listen to an old lady about a legendary pokemon who only appears in the night.)
So, after reading all the story, i found my rival, then 2 guys from team plasma came and my rival asks for my help and starts the battle, so, when those 2 members of the plasma team raise their pokemons the game crashes and it returns me to the main menu of Drastic.
Somebody can tell me what is happening? Im getting mad.
I've tried to dowload other Rom (White 2) and its the same, please, if somebody can help me i'll be really happy.
Sorry about my english, but im mexican and im still learning the language.

Do you have cheats enabled?

Do you have cheats enabled?

Just the 100% catch, but i disabled it and nothing change.
Im trying without cheats and low quality and keeps crashing

After disabling the cheat did you reset the emulator and load an in-game save?

Well after all I think i got the problem solved.
Looks like the problem was the savefile on the rom.
So, i dowloaded the ROM again and it worked, i got
even my savefile so now i can continue playing.
Thanks here for the help, I'll kick some team plasma asses for celebrate!.
