Vermouth has been released in version v2.6.0.

After version 2.5.0, the update brings a DOSBox Staging runtime, a GPU selector for multi-GPU systems and a runtime filter for the game grid.

v2.6.0 - DOSBox

DOSBox support, GPU selection, and a runtime filter for the game grid.

New Features:

• DOSBox Staging runtime - Enables DOS game support with folder, program, and configuration file compatibility. The system auto-detects GOG-style dosbox*.conf files and supports CD/floppy mounting. Users can download DOSBox Staging directly or use their own binary.
• GPU selector - Multi-GPU systems now allow users to designate which GPU runs each game via Settings or per-game editor.
• Runtime filter - A dropdown menu filters games by Windows (Proton/Wine), Linux, Retro, DOSBox, or UZDOOM categories.
