 It helps if you post additional details:
     the spec of your PC
     the DOS edition & version
+    the Game title and edition & version, and where/when the problem appears
     the build/release of SBEMU, if you don't know, you can check the startup message (the first line) of running SBEMU

 Because SBEMU is a hobby project, there's no guarantee that the problem will be fixed immediately or very soon enough,
 and the contributors might not response in time, please be patient.
