Hi krikzz, I have a problem with the cart. I have paste de EDFC folder on sd card and 2 more folders (Nes-famicom) (FDS) -root- The main problem is that, always os is loaded and I can see the 3 folders but suddenly all is frozen. Pad doesnÂ´t work and screen is frozen. Sometimes I put the Twin Fam. ON and seems that os got problems to load. IÂ´ve seen 3 or 4 types of Error. Lot of problems. Of course I canÂ´t open a file (rom). IÂ´ll try to make a short video if can help you. Thanks. * IÂ´ll try to format de micro sd first.
