In 2019, there are some Switch flash cards for you to choose to attack the Nintendo Switch. They are Xecuter SX Pro, R4s Dongle, SX Gear, Acens and more. Here, I will give you a brief introduction. Xecuter SX Pro: This is Team Xecuter's first Switch flash card, which includes a Switch RCM jig and an SX Pro usb dongle with an SX OS license to launch the SX OS CFW on the Switch to play free games and enjoy homemade games. In 2019, the Xecuter SX Pro was the best Switch flash card. Xecuter SX Gear: It also comes from the Xecuter team. Basically, the Xecuter SX Gear is the same as the SX Pro. They only have one difference. SX Gear does not get the SX OS license in the usb dongle. Therefore, its users need to purchase the SX OS code to run the SX OS on the Switch, or you can simply install any other CFW on the Nintendo Switch using SX Gear. It is an "empty" SX Pro and supports the SX OS. R4s Dongle: R4s Dongle is the only Switch flash car from the r4 3ds team, produced by R4 tem R4i-sdhc.com, which is also used to inject a payload into the Nintendo Switch console to launch custom firmware. Like SX Pro and SX Gear.This is the cheapest Switch flash card in 2019.
