I like the new version of AuReiNand but my menuhax loading of GW doesn't work with it so I dropped back to 3.12 and still use arm9select to load A9LH payloads. Once GW gets off their butt and creates a A9LH payload I will update back to the latest and greatest AuReiNand.
@SirBeethoven, If you use arm9select with AuReiNand it will take priority over the AuReiNand loader allowing you to more freedom as a sysNAND user. As a sysNAND user you can map a.bin,b.bin,x.bin,y.bin,up.bin,down.bin,right.bin and left.bin all without having to use any other buttons. Great for sysNAND users for emuNAND not so much as a and b are used by AuReiNand to boot a second emuNAND if you have one and a to get back to emuNAND after playing GBA on emuNAND or exiting settings of emuNAND. Not that I can think of more than 6 A9LH I need. I use decrytp9 and uncart currently. If I need to do some emuNAND stuff I drop in emuNAND9 for a bit and delete when done (swapped to a 128 GB microsd from a 64 GB yesterday).
