The r4i card and the new nintendo dsi XL

Hello
I´m all new in here and english is not my native language, so be gentle with me...
I´m planning to buy the new dis xl for my kids, but will it be compatible with the r4i card and the games downloaded in here ?Another thing; Is there a really idiot-proof how to do step by step guide in here on how to get the games from in here to the dsi xl ?thanks

So.. You can use the R4i on the XL because the XL has the same firmware as the old regular DSi. So as long as nintendo doesent bring out a new firmware, or you dont download the new firmware you are fine.To set up the R4i, heres a guide:
