!!! DO NOT UPDATE!!!Nintendo as usual is up to their old tricks, they have recently released a major new firmware for their popular 3DS handheld and as such it breaks a number of good exploits on the system, one of them being 'fasthax' and another being features like 'emunand' that depend on lower 'native_firm' value, but not to worry both the Gateway 3DS Team and scene developers like SMEA are already hard to work at figuring out all the patches that big 'N' did and will have workarounds soon for most of the old exploits, and as usual we will most likely see new great things coming also soon!
Just a friendly warning, Please Do Not Update your EmuNAND to the newest v11.3 firmware from Nintendo that was just released, as you will not be able to boot into EmuNAND afterwards, due to the fact big 'N' has finally patched, the minor version of 'native_firm', but don't worry an FIX is incoming, and soon everything will be back to normal!
So there you go, for more info you can check out the following links, in the meantime, feel free to comment here on our forums what you have discovered, but please DO NOT UPDATE until more info has been gathered and FIXes have been officially released for this new v11.3 update from Nintendo.
