Hacking Gateway save files for eshop VC .3ds files

[auntnadia]

i've found a lot of Eshop VC roms as .3ds files recently. They work fine, however if I load another game or switch off the console, the save file becomes corrupt and resets when I reload the rom. Have tried it with 5 roms and 2 SD cards. Normal retail roms work and save just fine. Any ideas?

So do I need emunand setup for the save to work?

Yeah, I've been saving via the bottom screen, then closing the rom with the home button. It seems it only happens with VC titles in .3ds format.

Haven't trimmed them myself. Off the top of my head, they are all EXACTLY the same size (I think 158mb.... give or take a few). For a VC rom, that seems to me surprisingly big, rather than trimmed?
