Sky3ds+ supports 3DS 11.0.0-33 and all lower/higher 3DS System version. Sky3ds+ supports 3DS Games without Limit. Sky3ds+ is plug&play, you are no need to use any other tools or softwares. 2.GATEWAY 3DS: Gateway is the oldest 3ds flash cartridge from 2013 to 2016. So it has many users and it take a very important role in the 3ds game hacking market. never dissppointed us except for the uncomplete 3ds compatibility. It only can be used on 3ds v4.1 to v9.2 till now. 3.DSTWO PLUS: It is the updated version of dstwo card. Now dstwo card which is a ds games flashcard has out of production. Then the dstwo team release this cardthe real 3ds game flash cartridge-dstwo plus, which can support ds/3ds/gba/snes games on 3ds consoles. We can also call Dstwo plus is combined the features of Supercard dstwo and gateway 3ds. If you want to play DS/GBA/SNES free games, dstwo plus is best to buy without GW plugin. But when useing the GW plugin, dstwo plus card users are under the risk that be banned by Gateway 3ds. So based on the above discussion, which one is your best chioce. My recommendation is the sky3ds + card, it is hard to beat in the market now.
