game loads fine, installed it on sysnand via freeshop since im on 9.2 and cant access eshop
emunand installation of legend of exidia is bought from eshop though
game loads, but i cant get the exploit to run after copying public.sav, game just loads as normal when i press continue
Sorry but It has to be obtained from eshop in order to allow access to NAND (the guide states this in a couple of places).
Since you are on 9.2 CTR-HTTPWN will not work for you. The part of testing the save is to make sure that it installed correctly, what version is your EmuNAND on?
This is tricky, I used 11.2 A9LH on SysNAND to downgrade my N3DS.
