I downloaded mupen64plus from the following link: https://github.com/mupen64plus/mupe...download/2.5/mupen64plus-bundle-win32-2.5.zip but it just doesn't open. When I execute mupen64plus-ui-console.exe, it shows a window with some texts on a black background, and just closes. I also tried a few more builds but none of them worked. My computer uses windows 8.1 K. Did I do something wrong? Please pardon me for my bad English..
