I have a DSi version 1.4U and I ordered my R4iTT card 2 weeks ago and received it this week. I ordered my card from [censored]s.com, it is a purple card that came in a purple box with mario on the front of box. The R4i card is version 1.6 and I asked customer support from the website I bought the card would it be compatible with my dsi since its version is 1.4U. They referred me to this website. I realize I have to buy another sd card, my current sd card is 2GB but the R4i card I have says it's only compatible with 4GB and up. Before buying another sd card I wanted to know whether or not I need to order another R4i card. Customer support told me I should be able to get the latest firmware from here. Any advice would help and thank you.
