White screen when I tried to run pokemon emerald on a Ti Nspire CX II

When I tried to run pokemon emerald on a Ti Nspire CX II, it just gives me a white screen and I don’t know the reason behind it. I reset my calculator multiple times. I have endless installed. It worked one thing and after that, it never worked and whenever I tried to run it, it just gives me a white screen. Can someone show me how to fix it or teach me? That would be appreciated!
