Gentleman v1.4.2 is released. Gentleman is a MiSTer-inspired emulator frontend for PC. The goal is to bring the simple, fast, menu-driven feel of the MiSTer interface to a PC-based emulator setup. Instead of using a database-heavy frontend, Gentleman builds its menu from a normal menu/ folder. Folders become menu categories, and JSON files become launcher entries.
