I failed in getting Pokemon Black Version working on my R4i Ultra card, and tried the latest AKAIO 1.8.6a kernel from r4iultra.com. Unfortunately it is always freezen at loading screen. Finally i Googled and found this Youtube Video, and now i share it out here. Select the Pokemon .nds file -> click "START" on right down corner on bottom screen and enter into akMenu -> Properties -> Rom Settings -> Disabled Bypass AntiPiracy -> OK
Thx it works nice i have tried all the kernels and nothing work but white this trick it works thx dude cane i make a youtube vid of this tut
