Dsi xl

I have just bought a DSi xl and could do with some help, I use a R4 card on my old DS but what do I need for DSi xl and where do I get firmware from, I would be grateful for any help. Thanx
:o

Thanx Ethan for responding, my old R4 card is NDSL/NDS so I am assuming no good for DSi. when I purchase this acecard where and how do I get firmware for it. ::)

The firmware for the acekard you are gonna purchase can found here http://www.akaio.net/forum/viewtopic.php?t=1080&f=8If you have an acekard then you must use akaio, 1.9.0 is the latest

Thanx guys.
