I don't have a M3i Zero but I have a M3DS Real, and I saw a video on the M3i Zero, it looks just like the M3DS Real. I too have problems with my M3 booting up. I also have an AceKard 2i and much prefer that over the M3DS Real. I think the menu works a lot better than the M3DS Real. I have ordered multiple time from GameByGame and 3 days is amount of time I waited for any order. Plus GameByGame is a good forum supporter, having contests and such. GameByGame is out of California, another plus since I live in the USA, probably accounts for the quick shipping.
