DMINLauncher v1.2.0

A cross-platform launcher for DOOM source ports

DMINLauncher is a simple launcher for DOOM engines. It is built with .NET 9 and Avalonia UI.

One of the main goals was to provide a consistent launcher experience that is easy to use with Batocera, Retrobat or standalone in either Windows or Linux. Cross-platform compatibility was essential for this to happen.

If you wish, you can help support this and other projects I am working on. If not, that is ok too.

Found a bug, want a feature? Let me know!
