GW3DS Nand Emulation:
After a lot of brainstorming sessions we decided it was time to realise one of the revolutionary ideas that we have in store for you! We have been working very hard to bring you our 3DS console NAND emulation solution that will allow you to run up-to-date firmware, without the need for spoofing!
To accomplish this feature a part of the 3DS SD card is used as a fully mirrored NAND image while still being able to use the SD card like normal.
The first step is BACKING UP YOUR NAND! Second, run our SD formatter from within the GW GUI to format the SD card with a unique copy of your console’s NAND. On the next Gateway boot, the console will automatically relaunch from the NAND image on SD, which means you can safely update to the latest firmware! Say hello to e-shop [;-)]
Ohh and MH4 is finally working [;-)] XY is officially WIP. Porting our patches from 4.5 to 6.3 is time-consuming and tedious so please bare with us for a little while longer, testing and safety is paramount for such a release. As always, we know you will ENJOY !!
P.S.: We have finally cleared all back-orders from the initial Gateway purchase rush. We are happy to announce that we are now fully in stock and that all new orders are shipped ‘next day’.
