Pokemon White/Black 2 doesn't start anymore

[Oneath]

Hi there, I have been playing Pokemon White 2 for a few months and its been fine, but since a certain time (could be end of 2014) I cannot play it anynore because after loading the game nothing happens and it goes back to the Drastic Menu, I tried Black 2 and it happened the same, by the way all the other Pokemon Games for NDS still work fine as always, but I really want to play White 2 and I have no idea how to fix that issue ... please help me ... I am using a Samsung S5 Cheers ^^

It could be the update of Android to 5.0, I am not sure whether it isn't working since that update or even earlier.

It's probably since the update, because it seems that large files like Pokemon White/Black 2 (512MB) can't be mapped anymore in Lollipop.
Try enabling the option Advanced > Auto-Trim, then load the game again.

Wow, thank you ! It works now ! Thats what I call a good Support

Auto Trimming must do the same thing as ROM patchers do. I play a Hack version of White 2 and its only 276MB instead of 512MB
