Btw. does anyone know how the hell redownload on e-shop works? Game is not linked to Nintendo ID on e-shop, and yet I can redownload it on different SD card. :D
CHMM2 seems to increase rate of FBI booting succesfully as well. I just used L+R+A to leave CHMM2 and FBI booted without problem. Someone recommended that some pages later. I will check it again and i'll send you an reply again to confirm it. Then you can pinn this in first post. ;)
Use DLAN from Settings -> Data management. It's faster than FTP. But still, best is to just to open your N3DS and put the card into PC with USB adapter. And dude, it's typical + screwdriver... You can unscrew this even with knife.
I don't know yet. I will check if I can still re-download it on different SD card. If so, that would mean that some ticket/access sygnature is on sysnand. But I'm not sure.
No, it's more like just pre-installed games from bundled consoles. Because I installed Super Smash Bros Legit CIA, then deleted it completely off my SD Card and yet I could redownload it from e-shop. (What I did indeed.)
