Sometimes, it's hard to decipher what he is saying exactly since his responses are so short, but he's apparently tried .5 as well. I initially thought about what menu version he was using when he first posted, but he already mentioned that:
"I have every time two white screens (in all the menus). Can anyone help me to solve this problem?"
So I assumed he has already tried .5 ... no harm confirming, though, especially .4 (since there are both .gba and .nds versions)
