Buying a new M3i Zero won't help since the M3 Team is dead and won't be making updates any time soon, it would be best to buy one of these cards; Acekard 2i, EZ-Flash Vi, Supercard DSTwo, R4i Gold, or CycloDS iEvolution (You don't have to buy from that site, I just like that site myself and always suggest it to people.)
Yes I know I post this a lot, and really I don't like to since I started out as an M3 fan myself with a lot of hope for them, but when something is dead there is nothing bringing them back so clinging to it won't help anyone.
