i tried using the latest nightly 2015-12-05 and it doesn't seem to boot up. tried the stable build, it boots up but lacks the region free component of the nightly. downside of the stable is that i have to boot up NTR just to have region free cartridges just to use my out of region games. which is the latest nightly that i can use? is the region free cartridge not implemented on n3DS or is it just not working on the stable build?
