A new update for the M3 DS Real has been released recently.
It looks like it is only a few bug fixes, nothing major. An update from the M3 Group to get towards 100% compatibility even though I have never had any compatibility problems. This update fixes a few problems with certain games.
To download, see Hand Held Resources . Once you have it, just unzip and put those files on your M3DSreal microSD card and overwrite any files it asks.
