R4 3ds-R4i sdhc 3ds rts, R4i gold-R4i gold pro 3ds, this video test the 2 flashcards on Nintendo 2DS XL/3DS 11.10.0-43 consoles. They are working directly with each own latest kernels, playing DS roms, no need to update. What I use is R4i gold pro 2017, the 2018 and 2019 R4i gold pro should support 3DS V11.10 as well, No Worry.
