DSi card is a slot-1 flashcard for Nintendo DSi, DSiLL and DSiXL. It is a good engine for games and multi-medias. Different with DS card, DSi card offers very good compatibility. It supports a MicroSDHC card (up to 32GB) to play games, listen music, watch music, E-book and so on. Except the original DSi card from Nintendo, there are also many other R4 DSi cards in the market. All these DSi cards are compatible with DSiLL, DSiXL, DSi, DS and DS lite console.
There are many DSi cards in the market currently. Such as Acekard 2i from acekard.cc, Supercard Dstwo from supercard.com, M3i zero from M3adapter.com, DSTTi from ndstt.com, R4i SDHC card from r4i-sdhc.com, R4i Gold from r4ids.cn, R4itt from r4itt.net, R4i Gold V2.0 from r4ids.com and so many other R4i series flashcards. All these flashcard are same size as original DSi card, and run well in Nintendo DSi console. Within them, Acekard 2i, R4i SDHC and R4i Gold card are most famous. However, Acekard is little more expensive, and it update software not very fast.

Nintendo updated DSi firmware to V1.4 version on 2008, which allows users to post photos on social networking websites. As a result of this firmware upgrade, a lot of DSi cards stopped working. Some of the excellent manufactured cards were able to be upgraded using a firmware upgrade of their own, but many other cards simply could not work on DSi consoles after the upgrade. The DSi cards which broke Ninendo DSi V1.4 firmware were called DSi V1.4 card.
Another update of DSi firmware is on Sep,2009. Nintendo upgraded firmware to DSi V1.4.1 version, and halt all DSi cards.
