Haha no it doesn't, that's what I get for being lazy and downloading someone else's cia instead of making my ownI just tried it and imported the save fine from the cartridge into the CIA-converted Luigi's Mansion.
Didn't have to create save data or anything. Just installed it and imported the save right away.
Are you sure your conversion went alright and the resultant game had the proper unique id? (0055F)
Many thanks, will try this properly!
