What MedLaunch is

MedLaunch is a free Windows front end for the Mednafen multi-system emulator. It scans and imports ROM and disc-based games, including multiple ROMs inside ZIP and 7z archives. Game data and media can come from TheGamesDB and MobyGames, while PDF manuals can be downloaded from ReplacementDocs. The launcher imports existing Mednafen settings and can configure nearly all Mednafen parameters. DirectInput and XInput support covers keyboards, gamepads, joysticks, and XInput devices. It records each game’s last-played and total play time and can generate a Mednafen launch string for editing or copying. A pre-populated netplay server list is included. MedLaunch checks for updates and can download supported Mednafen x64 binaries, but development builds are not available through its internal updater. Settings use a local SQLite database, and the project says no data is written outside its folder. It requires .NET Framework 4.5.2 or later, does not support Windows XP, and needs no installation.

Who it suits

MedLaunch suits Windows users managing Mednafen libraries who want metadata, controller configuration, launch-string tools, and netplay server listings. It is intended for systems running Microsoft .NET Framework 4.5.2 or later.
