Hi my name is gavin im new to 3ds stuff but i got some games and i want to stream so if you have a card that will work with my O3ds xl plz respond ill pay good

It sounds like what you're looking for is a capture board installation and as of right now only Katsukity is doing those and sometimes Loopy will do them too but according to his website he only does original 3ds and according to streamers I've watched, original DS's. In this group you'll find people buying and selling used 3ds's with capture boards already installed or as they're simply called capture cards. There are two brands of them Loopy which can be available in original 3ds or DS, or Katsukity which can be available in any model. I've observed from many streamers that Loopy cards are sturdier than the Katsukity ones.
