I don't recall, it's been a few years since I played them. I don't seem to remember having any problems though.
I have OoT on original cart, MM I played on a flash cart, then installed a cia on a cfw 3DS. I was going to get the original on discount, but they ran out of stock.
Triforce Heroes (bought on discount) is worth a look.
is that like oot/mm or classic zelda?
