Pokemon soul silver black screen at pokemon raiser

Well, I've searched on the forum for this particular problem but i couldn't find it, so I made a Thread myself. Now, the problem accured after visiting the Pokemon raiser for the first time, you know you get that conversation with the grandpa and then the grandma of your friend (if you're a boy it's a girl, if you're a girl it's a boy) after that you are in the house of the Pokemon raiser with that grandma. If i try to do something like talking to that grandma i get a black touchscreen and i can't do a thing, if I try to open my bag then i get 2 black screens. I can't do a thing, leaving the house gives me 2 black screens too and saving 1. I can only load from my realtime save because if i try to load the game the usual way it doesn't load at all (2 black screens). So please help, is there a fix for this or whatever?

I'm using a supercard ds one
