Pokemon Black/White 2 r4 (r4ids.cn)

So I just got this r4 and I am really new to this. Now to my problem. I downloaded the new wood kernel from r4ids.cn and when I try loading my pokemon black/white 2 Roms it doesn't work. It says it is loading in white letters, then after a little bit the loading turns red and doesn't work. Every other rom that I have is working perfectly. What is the problem? And how would I be able to fix it? My r4 card is the r4 3ds gold.

Thank you so much I didn't know it had to be >8. I owe you as many dirty favors as you request hahaha ;D
