What is gentleman?

Gentleman is an emulator frontend for Windows, meaning it is a launcher and menu system that sits in front of your collection of emulators and games. Instead of launching each emulator separately, you open Gentleman and navigate a simple menu to find and start any game across any system you have set up. The interface is inspired by MiSTer, a hardware emulation device known for its clean, keyboard-and-controller-driven menu experience. The menu is built from a folder on your computer called menu/, and the structure of that folder becomes the structure of the menu. Creating a subfolder called Consoles and placing a PS2.json file inside it will produce a Consoles category in the menu with a PS2 entry inside it. Each JSON file describes one launcher: which emulator to call, where your ROM files live, what file types to look for, and any extra arguments to pass. You can create and edit these launcher files from inside the app rather than writing them by hand. The tool supports three types of launchers. A standalone launcher calls an emulator directly with the selected game file. A RetroArch launcher specifies both the emulator and a particular core plugin to use for that system. An application launcher opens any program without a ROM selection step, which is useful for adding things like a game store client to the menu. Navigation works from both a keyboard and a game controller. The app tracks recently played games and lets you mark favorites. A settings menu lets you toggle the recent list, favorites, fullscreen mode, and controller button layouts. There is also an in-game overlay you can open while a game is running to see what is active and close it if needed. Gentleman is a Python application and currently focuses on Windows. The project is experimental and is not connected to the official MiSTer project.
