My R4i-SDHC 3DS only supports 3DS firmware 3.0. I'm on 4.20-9U, but r4i-sdhc.com doesn't have a firmware download link anywhere. http://www.linfoxdomain.com/nintendo/ds/ only has the kernels, not the firmware. Does anybody know where I can find the firmware to upgrade my flashcart? Their instructional screenshots show that they have firmware supporting up to 6.2, but I can't find the link anywhere. I'm also looking for the Acekard 2i firmware update for 4.3. Again, I am having trouble finding it since the Acekard site is down.
