I'm getting a 2DS XL soon and I'm reading the guide on how to install B9S. I have a Acekard 2I (very old) HW:81 and running AKAIO v1.9.0. It says in the guide that to make the Acekard work you must be 3ds 4.3. What does that mean? Is my Acekard compatible? I have an old 2ds (which my daughter now has) running BS9/Luma which my Acekard works with. Also I'm a little confused with the tutorials. There's a tutorial if you have a flashcard and a single 3DS and a tutorial if you have a flashcart, stock 3ds and cfw 3ds. What's the difference between the tutorials? as what's the point in using a second cfw 3ds if there's a tutorial to use one without it.
