I've read in a few threads that DS games on 3DS is not advised because the image quality takes a hit. Is this true for cfw/TWilight? Surely there are a myriad of video options available? Anyone got any comparison shots showing why it's a bad idea? Usually I play games stretched to fit at the same aspect ratio, with all filtering off, but I don't know if that's the best thing to do here. I have a CFW DSi and n3ds, but ideally would like to sell the DSi on if possible.
