Are the save files [whatever].sav? Cyrgor/miotool only handle raw saves. Maybe a savegame converter could help. I don't know if
this can deal with the 32MB saves, but give it a shot.
Edit: I don't think it's been said "repeatedly"; this is only the second time I can recall it coming up.
Edit: Ok, as far as I can tell, while M3 Real makes the right
size of saves, they're not the RAW format that is expected.
This might work?
Edit: Nope, spits out a 512k file from raw save to .0 (which it says is the M3/G6 DS Real format.)
One last edit: I contacted the guy who wrote the offline save converter and suggested added support for DIY's 32MB save. We'll see if it happens.
