You could go with Skylock suggestion of the iEdge if you wanted to. I'd probably stick with the Acekard though, I like the interface.
All of these carts require a firmware update to work with the DSi 1.4. The Acekard requires you insert it into a DSLite or DSi with 1.3 Firmware or below and then run a NDS file which you can get from http://gbatemp.net/index.php?showtopic=174523&st=330. The iEdge on the hand is more complicated but will update if you only have access to a DSi 1.4.
If you want the iEdge, Deal Extreme have it for $14.75 https://www.dealextreme.com/forums/Forums.d...threadid.523912
