Ok. Since you couldn't get into the chat room, please try the following: Launch Before: start "" "E:\Emulation\Emulators\Nestopia v1.40\batch\NestopiaStartup.bat" Launch After: start "" "E:\Emulation\Emulators\Nestopia v1.40\batch\NestopiaExit.bat" Launch before/after was designed for executables in mind. However, tweaking the command-line will make it work.
