Pretty shitty card, indeed. Don't buy it, it's a waste of money. You know that emuNAND was discontinued since R4 4.0. And for over 7 months (7/2014 - 2/2015), there hasn't been any update from them.
I just went from R4 to GW, and got mind-blew!!! The GW can do emunand, play eshop titles at 97% compatibly, run homebrews, and so on... Just go buy the GW. It's a sexy piece of hardware.
