MedLaunch is built for Microsoft Windows only and has been tested on Windows 7/8/10. It will not work on Windows XP due to the .NET version it is built with.
A 64-bit operating system is preferred, although it should work after a fashion on 32-bit windows with some caveats:
MedLaunch is currently built using the Microsoft .NET Framework 4.5.2. You will need at least this version of .NET 4.5 installed for the application to launch.
MedLaunch is currently a mouse and keyboard affair, with no current plans to implement gamepad control of the UI.
For a number of emulated systems that Mednafen supports you will need specific BIOS/firmware dumps. From a legal standpoint, it is up to you to acquire these.
The will need to be placed either in the root of your Mednafen directory, the 'firmware' folder within your Mednafen directory, or another location that you can locate through MedLaunch (on a rom by rom basis).
The default ROMs that Mednafen looks for are shown below in the MedLaunch settings:
Mednafen is pretty choosy about which particular firmware you need. You will have to locate the following firmware/BIOSes:
