Recently, Nintendo update 3DS firmware frequent, from V9.2.x to V9.3.x ,then to V9.4.x .
Gateway team isn’t free too, they are working hard on V9.0-V9.2 firmware, and just now, release the OMEGA 2.7 firmware.
The following news is from Gateway 3DS official support site:
Today we present another quick update for our 4.5 users: Gateway OMEGA 2.7 which brings support for emunand 9.4!
We also want to inform our users that we are still working on native support for sysnand 9.0 – 9.2, so please be patient until we are ready to release!
We try to deliver a smooth experience for our users and this takes time to perfect!
We also inform our users that they MUST NOT UPDATE SYSNAND TO 9.3 OR ABOVE, because we will not be able to support entry to those sysnand versions any time soon.
If you are wondering what native support we will bring for lower than sysnand 9.0, we can tell that after 9.0-9.2 we will start with 8.0-8.1 and gradually work our way down with support for even lower sysnand firmware versions.
