- Windows and Linux Portable Mode.
- Rom loading from the command line by adding the rom path as an argument.
- Support for modern game controllers through gamecontrollerdb.txt file located in the same directory as the application binary.
Tips
- Boot ROM: Gearboy can run with or without a Boot ROM. You can optionally load a Boot ROM and enable it.
- Mouse Cursor: Automatically hides when hovering main output window or when Main Menu is disabled.
- Portable Mode: Create an empty file named portable.ini in the same directory as the application binary to enable portable mode.
- Docking windows: In debug mode you can dock windows together by pressing SHIFT and drag'n drop a window into another.
- Debug multi-viewport: In Windows or macOS you can enable "multi-viewport" in debug menu. You must restart the emulator for the change to take effect. Once enabled you can drag debugger windows outside the main window.
- Debug Symbols: The emulator always tries to load a symbol file at the same time a rom is being loaded. For example, for path_to_rom_file.gb it tries to load path_to_rom_file.sym. It is also possible to load a symbol file using the GUI or using the CLI.
- Command Line Usage: gearboy [rom_file] [symbol_file]
