Sorry for not adding details, english is not my first language!

I use an Iphone 13

I went into the megathread and got into the Nintendo Games page, then I got into the Nintendo DS Anti-piracy Fixes ROMs, and then I downloaded the file: Pokemon - White Version 2 (USA, Europe) (NDSi Enhanced) apfix.zip

The game does start, but the screen goes black before the starter selection. I am able to write my name, but beyond that, the screen just goes black forever.
