So far i have tested the following: Working-- r4igold ( r4ids.cn) : Works fine without any patch needed on 7.0 Supercard ds two: works on 7.0 but needs patch because it got blocked r4isdhc dual core ( r4isdhc.com) 2013 card: Firmware patch: http://www.r4isdhc.in/download_white_new2013/index.html Use Kernel:https://www.dropbox.com/s/zk8sl1t2ef4917o/r4isdhc1.70.rar. ( using 1.62 kernel will result in blank screen when launching ds games so use 1.70) r4i3d.com pink 2013 card r4i-gold ( r4i-gold.com) 2013 card r4itt ( r4itt.net ) purple '' new'' ( not to be confused with the new 2014 one) card- This card was the latest compatible with 6.2/6.3 All cards mentioned above are working in 7.0.0-13U 3ds updated systems, simply apply the same exact steps used for the r4isdhc dual core card, even using the EXACT firmware patch and kernel. Once again proves that all these cards ( r4i3d.com, r4i-gold.com, r4itt.net, r4isdhc.com) are alike besides colors and stickers. UPDATE All this cards work on 7.1 as well without any sort of patched needed. Also i should state that the new 2014 r3isdhc.com cards ARE different than before. They have an extra part in the chip, as well as different kernels. These firmwares and kernels are NO LONGER interchangeable between the new and old cards. The new 2014 cards from r4isdhc.com are very much like the ones from r4i-sdhc.com it kind of looks like they rip some of their kernels to be honest. These new cards also didn't require a patch from 6.3 to the 7.0 upgrade they worked fine without them. I tested this with the r4i snoopy, white dual core 2014, and the gold pro 2014 from r4isdhc.com. All these cards have the same exact kernels, and probably firmware patches they are exactly the same inside the ONLY thing that is different is the sticker design and color of the card. For your old cards from r4isdhc.com ( 2013 models), use r4isdhc.in for future patches and kernels. r4isdhc.com still posts firmware patches for old cards but they are much slower than r4isdhc.in.
