Yeah, I got an Acekard 2i for my DSi and it works great, just refrain from updating your DSi's firmware because Nintendo could block the Acekard form working. But the latest firmware as of now is 1.3U and it is confirmed working on1.3U.
I also have Acekard 2i for my DSi. (working with 1.3U without any problem right now) it's really great.
Hi, just wondering where U posters above ordered your Acekard 2i from? Cheapest I see is from DealExtreme, $12.97 USD Free S/H http://www.dealextreme.com/details.dx/sku.18728
