The WHDLoad quit key can be registered for WHDLoad variants now. This allows FS-UAE to quit gracefully without losing data – some WHDLoad slaves to not save state until they have (gracefully) exited. Once the slave exits, FS-UAE will then close normally.
Example: if the WHDload slave expects the user to press the Amiga ‘Help’ key to quit, you can register
whdload_quit_key = 5F. See http://whdload.de/docs/en/rawkey.html for a list of valid raw key codes.
