There are too many kinds of R4 3DS flashcards in the market currently. I hear somebody said, few 3DS cards may causebreak to the 3DS console, is it true? I have already bought one from an onlinestore ps3breakr4.com, which can beused smoothly. If the R4 3DS is not safe for the console, we have to take careto use it. But how to distinguish them?
Compatibility with 3DS Console
Several manufacturers have already announced their cards will be playable onthe 3DS console. These manufacturers include the R4i team, as well as Acekard,M3i Zero, EZFlash, and so on. It appears at this time that most cards will beavailable to play without issues.
However, note that just as with the 1.4.1 firmware update, the R4i card in particularrelies on using cheap components (it is usually one of the cheapest / budgetcards available on the market) and therefore will work, but only if a new R4iis bought. The technology to update the firmware of the R4i card is notavailable because it would drastically increase the cost of the card.Therefore, for an updatable card alternatives we could recommend include theAcekard 2i and M3i Zero at this time.
Compatibility with 3DS / 3D Games
At this time, it is important to note that all cards that say they can play onthe 3DS, can indeed play – BUT only for existing DS / DS Lite / DSi games. Asbefore, DSiWare games as well as new 3DS games cannot be played using backupcards such as the R4 SDHC v2.10T / R4i SDHC.
Therefore, we conclude that only regular games can be backed up as it currentlystands, and new games in 3D cannot be backed up at this time.
