With the release of the 1.4 firmware for the DSi, Nintendo added a few additions such as a faster* camera, Facebook photo uploads, as well as blocking various flashcarts such as the R4i. This should be an excellent test for those flashcart makers of the M3i Zero and Supercard DSONEi to see if they can find a workaround, since they have an external method of updating firmware.

Other flashcarts which cannot reflash their firmware like this, will be useless on a DSi with firmware 1.4 and above. If you have one of these, make sure to keep updated on the scene news.
