Nintendo Dsi xl w/ R4 original :O?

First off all hello everybody i dont know if there's already a thread out off there for this problem
so yesterday my original nds lite broke and today i bought myself a dsi xl and well i tought yay! bigger screen lets play!
but i putted my r4 in the card slot and it seems that the dsi xl doesnt read the card or somthing lol Help me please any solution off this?josh~

You need a dsi flashcartr4i
ak2i

original R4 is not compatible with the DSi. You will have to buy a new flashcart (we recommend the acekard 2i).

okay thanks for the fast help il buy my self an acekard 2i :/
