The R36S Ultra is the flagship of the R36 family. It pairs the RK3566 chip with built-in Wi-Fi, Bluetooth, RGB analog sticks, and a tempered glass OCA-laminated 720×720 screen. RetroAchievements work out of the box via Wi-Fi. N64, Dreamcast, PSP, and NDS emulation is substantially better than the base R36S.
