Currently with the newest update EZ5 autohybrid (makes games run faster)....has near 100% games working, has soft reset for commerical titles, has automatic save file size recognition, Download play is hit or miss...
They don't currently support game cheats, or slo mo....but are working on it for the next update!!
I bought an ezV as a bundle with the 3-1 ez. And I love the 3-1. Rumble, GBA, and the RAM for opera and other things starting to use it. Everyone brags about R4 and cyclo but ezV is great. Get a good deal and pick up the bundle. You will be happy if you like GBA games and don't have a way to play them or if you want rumble and opera browser
54$ for a 1 gig microsd + ezV + 3-1 at winsunx.com
happy shopping.
