I have the same problem, I just bought an R4 SDHC Dual-Core and I can't come to make it work. I tried a couple of Kernels and it's starting to get really annoying !
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
