There are few NDS flashcards that have up-to-date firmware and kernels (that is, can be played in the latest systems AND play all the latest games). Aside from the evr-popular DSTWO, R4i Gold (and a few other R4s), there are not many left. The M3i0 (M3i Zero) is one that has an official update to be able to be started in the latest DS systems but has a 3rd-party firmware that works, albeit a rather recent one. (Only the GMP-Z003 is the one that actually works in both areas, though...)
I am planning on buying this card.
