I put in my genesis and nes cds i revieved and all the games are in zipped folders. the ones that look like a folder with a zipper on them. When i double click one of the folders it has another file in that, then when I open that it says i cant open it and its a .bin file. How do I run these games using Gens and virtuanes, do i need to extact, download something? No idea what to do, looking for instructions.
