V1 have only 200 file límit in a folder and is very slow, specially when you are in a Game with bat, and change to another ,then saving to sd card can take several minutes+ reflasing. I not sure if v2 is more faster. But i buy the sd2nes and i very happy so i probably sell the v1. When i buy It sd2snes not exist.
I tell that because is not write in the first Page info.
