Apparently still plagues the M3i Zero even after the supposed update from the G6 Team quite a while ago. It works fine on a normal DS but won't work on my 3DS and quite frankly I am not carrying around two devices to play games. So while it worked initially on my 3DS, my card hasn't booted up since about 2 weeks after the little update came out for it to fix the problem. At this rate I am about ready to go back to Super Card, that's how unimpressed I am with the support from the G6 Team with this product. Kinda sad how great the M3 Simply was as one of the early Slot 1 cards for the DS, yet even 6 months after release there were no more continual updates to fix bugs and compatibility issues just like there is with the M3i Zero.
