I have HyperLaunch running everything. Your working path points toward the the HyperLaunch.exe and your command line should look like the example below. I would refer to Hyperlaunch.net for any in depth questions. HyperLaunch is the best as I can use multiple emulators for each system, pause screens, and the most difficult task is reading the module notes to setup each emulator correctly. Reading isn't difficult so I'm launching just about everything quickly and easily with their simple instructions. Lovin' it. Examples: Super Nintendo Entertainment System Working Path: C:\HyperLaunch Command LIne: HyperLaunch.exe "Super Nintendo Entertainment System" "[ROM]" Sega Saturn Working Path: C:\HyperLaunch Command LIne: HyperLaunch.exe "Sega Saturn" "[ROM]" Sony PlayStation 2 Working Path: C:\HyperLaunch Command LIne: HyperLaunch.exe "Sony PlayStation 2" "[ROM]"
