Inazuma Eleven 2 Kyoui no Shinryakusha Fire

When i run this game on NOSGBA 2.6a everything is fine, i checked if it works on NOSGBA in sticky thread "Compatiblity and SS" and it is there.
My problem is, when i get to first challenge when entering the destroyed school the game crashes. "THE ROM IMAGE CRASHED." Please tell me EXACTLY what i should do, btw game is working on Desmume but it slows down in some moments and voice is not so good and i dont know how to speed it up with "+" like in NOSGBA. Or maybe some good settings for desmume.
