M3i zero dsi flash card is the most powerful flash card and best-selling product among all super cards. It has so many unique techniques, such as upgradable “Boot Flash data”, upgradable “Kernel” and upgradable “Firmware” and so on.

M3i zero can be compatible with DS, DS lite & DSi. It supports real time save function( you can save and restore at anytime, anywhere), multi-language system (English, French, Germany, Italian, Spain, Portuguese, Dutch, Korea & Thai Language), micro SDHC (capacity over 4GB, 8GB, 16GB & 32GB …), reading individual cheat code file too(xml, cht, dht, dat-R4 format), rumble pack, GBA expansion pack & DS Browser and 4-scale-lightness adjustment.

To enable it, there are eight steps you shold take:
1. Download m3ifirmware.zip.
2. Unzip it, and drag that 1 file (F_CORE.DAT, its the upgrade file), and 1 folder (SYSTEM, its the software the M3 real needs to run on) onto your micro sd card. Make sure the file and folder at in the “ROOT” of the micro sd card, the very top!
3. Put micro sd card into the M3i.
4. Put the upgrade cable into the M3i (the shinny side, i.e. the side with the ARROW on it should be facing the BACK of the M3i!)
5. Plug the USB port into your PC, or anything that has a port that will give it power.
6. The M3i should blink for about 15~20 seconds. After it stops blinking, your M3i is enabled.
7. Unplug the upgrade cable from your PC and M3, and then put your M3i zero into your DS/DSi, and it should be working.
8. You can now delete the file F_CORE.DAT from the micro sd card as it will no longer be needed (its only needed to flash your m3i once!)
