My NANDS are linked. 1. Can i access the Eshop from the Emunand without any problem? 2. Can i safe upgrade my 3DS via SD without screwing anything? (o3ds RxTools+Cboot+Themehax version 10.7 emu 9.20 sys) It's weird, i use themehax so i know they are linked because when i tried to change my theme using CHMM in emunand i got the custom theme in my sysnand and the Cboot stoped working. So i got rid of the theme and tried tinker, installed the cboot again and got rid of the custom theme on the sysnand. Now i tried out Tinker, it said it was "succesfull" but when i used the RxTools emunand it didn't have any theme, however the sys had the custom theme, so i'm not 100% sure if they are linked.
