Using R4ii New Revol. for DS for Poke B&W and get white screen

Hi guys,
I have a Nintendo DS Lite with a R4ii and 2 GB & 8GB sandisk microsd card
but I'm having a problem with my R4ii New Reolution for DS when it comes to certain roms,
such as
Pokemon Black
Pokemon White
One Piece

they only display white screen,
and I cant find anything on the R4ii !
i went to the r4ii website written on the card but the link doesn't work
i read through quite alot of the posts in the forum for 3h or so already.
tried dl-ing this kernel thing and overwriting my system but still doesnt work so reverted it back

please help :'(

 

Okay. What card do you have?
The 'R4i Revol.' name isn't helpful in the slightest.
Post a picture of your card and the website listed on it (I don't care if it is dead).

 

sorry for not providing the pic when i asked the question..

this is the R4ii i have
