I successfully installed A9LH into my 2DS and it works really well. I've got 10.6 emuNAND and 9.2 sysNAND. My question is: is there a way to use more than one SD card on my 2DS? because i want to use more than one emuNAND. I tried to put a new SD card with all the files of the older one, but when i try to setup an emuNAND with the Gateway Launcher, it doesn't start (the launcher).... Solved! If you search in the forum, there is an application called 3DS Multi emuNAND Creator. Download it and download also emuNAND Tool. So insert the SD with the emuNAND in the PC and exctract the emuNAND (save it on the desktop) using emuNAND Tool. Then put the new SD card and open 3DS Multi emuNAND Creator. Click "format" and select the file you've just created on your desktop. Then, cose the application and open again 3DS Multi emuNAND creator and inject the emuNAND you saved on the desktop! That's all!
