I'm pretty noob about it but... are my Sysnand and Emunand linked even when I don't have a NNID? I tried to log in in my O3DS but I couldn't cause Sysnand is in 4.5 (Emunand is in 10.3 BTW), I don't have NNID cause needed to format my O3DS before the downgrade cause the thing didn't want to open the browser or update I've messed up the thing twice already.
1.- My games were deleted twice, surely I remember I've entered to data management in Sysnand once, but the second time I don't remember to have done anything special...
2.- My save data of my Majora's Mask cartridge was destroyed when tried to play it in Emunand 10.3, didn't asked me anything, is there any workaround to be able to use it (and in the future preserve the save game of any cartridge) without dumping it? I've seen over there that I should just play it in Sysnand, but it is iso low and it doesn't run.
