Gateway currently only work with versions from 4.1-4.5. It may never work with 6.3 or higher as quoted from their website:
"Currently it is not compatible with firmware above 4.5 but we are working on making it compatible as quickly as possible with 5.x and 6.x firmwares. It is most likely to happen in the weeks to come since we are now done with V1.0 of our product and can now fully concentrate on newer firmware and new functions. Since the product is now released and soon in Nintendo's hands, anything above 6.2.0 will most likely never be compatible. In any case: NEVER update, as we never know if we can make a fix for any update. Remove automatic updates by enabling parental control to prevent any accident. We can't repeat it enough, do NOT update if you want to be able to enjoy the only solution for your 3DS: Gateway! You have been warned!"
Hopefully they release a 6.2.0-12E update soon.
