The M3i Zero is the latest flash card offering from the M3 team. This new card supercedes the M3 DS Simply and M3 DS REAL. The major feature of the M3 Zero is full core upgradability which no other card on the market supports. This means that you can be safe in the knowledge that you can always upgrade the core FPGA of the M3 Zero without the need for a second DS, complicated applications and steps or third party programming device.
As the Nintendo DSi console is fully upgradable and requires regular updates for new features and additional functionality, you will be best suited with a flash card that is core upgradable as well as Operating System. (All flash cards are 'system upgradable' as you can always download the latest operating system and install on the MicroSD card, no other flash card at time of writing can be CORE UPGRADED or firmware flashed as easily as the M3 Zero).
The M3 Zero is compaitble with the following DS Consoles:
Nintendo DS
Nintendo DS Lite
Nintendo DSi
The M3 Zero features all the same great aspects of the M3 DS Real including Sakura firmware compatibility, Real Time Save (RTS) which allows you to save your game at ANY point, rather than waiting for a save point. Aside from this, it is compatible with all homebrew and third party applications. You can turn your DS Console into an E-BOOK reader, movie player, MP3 or full entertainment system.
The M3 Zero ships as a blank card, so it will need the core and operating system installed when first setup. You can download the software and files from this link. |
