Since you tried the cartridge first after deleting the tickets, it might be worth deleting them again but trying a CIA install first instead. The logic being that the cartridge might be writing a bad ticket or something weird like that.
Maybe you've already tried this but I thought I'd suggest it anyway. Also it might be worth getting a .3ds version and convert it to .cia yourself.
