 ### I tried launching SSNES in Windows with a different program but there's an annoying command line window there. Any way to remove it?
 You can pass the -D flag to SSNES which will terminate the console window if you launch it outside cmd.exe (from a shortcut or something like that).

+### I am using OpenGL driver, and when I do fullscreen, the display stretches over both my monitors. Is this a bug in SSNES?
+
+Not a bug per se, but rather a quirk of SDL 1.2. To remedy this issue (go fullscreen on a single monitor), you should set the environment variable SDL_VIDEO_FULLSCREEN_HEAD to the index of the monitor you want to use for fullscreen. I.e. you can add `export SDL_VIDEO_FULLSCREEN_HEAD=1` to your .bashrc (or whatever shell you're using).
