The M3i Zero is the first card to use specialist hardware to upgrade its firmware, coming with a firmware cable. thus allowing it to bypass Nintendo's DSi update system.

The M3i Zero firmware was co-written by the creatoe of the popular Moonshell Multimedia Software for DS & DSi Card. the firmware also called Sakura O/S .As you known,The firmware is one of the most comprehensive and well written pieces of software available for any DSi card, and was the first in the world to support smooth scrolling.

The M3i Zero allows you to directly run homebrew software on it – that includes emulators, PDA, browser etc...Also it can run GBA Games on DS/DS Lite that have a GBA expansion cart. (No GBA compatibility with the M3i Zero running on the DSi because it haven’t a GBA expansion slot.)
