I'm from SFC III files, and I just got BC from my uncle, so I install BC, works fine till I put patch in...I can't see anything out of the viewscreen in Single Player and Quick Battle but white...(including in Tactical camera!)!! How is this fixed?
Try turning off all the stuff in video options and play at the lowest resolution. If it works start testing by adding one each time and see which creates the problem. Get latest drivers for your video card too and service pack for windows.
