No, you're still misinterpreting it.
Gateway did announce 10.3 compatibility yes, but they STILL require you to downgrade to 9.2. They're currently developing a safer way to downgrade from 10.3.
Currently for you, there's no way to access emunand unless you downgrade to 9.2. You can install menuhax or any kind of hax, but they're all homebrew and does not give you access to emunand in any way.
ok I see.
Thanks for that info.
I guess i'll just wait the GW official downgrade method. If i remember, my pokebank licence doesn't end yet. I have time.
