I just recently purchased the R4i Gold 3DS from r4ids.cn, and it won't work with my 3DS updated to 2.2.0-4u (most recent software that was on Super Mario 3D Land game). Their website claims it is compatible (http://www.r4ids.cn/news.htm), but I can't seem to get it working with any combination of firmware and/or kernels of off their website. I figure someone on this forum may have had the same issue, so just trying to find the solution.
