This file only lists options not already described in ``-h``.
There is no GUI to configure the emulator: either manually edit the configuration file ``applen.conf`` in the current folder or use ``qapple`` and run ``sa2 --qt-ini``.
## Configuration
There is no GUI to configure the emulator: either manually edit the configuration file ``~/.applewin/applewin.conf`` or use ``qapple`` and run ``sa2 --qt-ini``.
The format of the configuration file is the same as the Windows Registry of AppleWin.
Individual options can be passed via arguments too: ``-c Configuration.Printer_FileName=Printer.txt``.
If you have a modern gamepad where the axes (``LEFTX`` and ``LEFTY``) move in a circle, the emulator will automatically map to a square: use ``--no-squaring`` to avoid this.
## Raspberry Pi
On a Raspberry Pi, one needs the KMS (fake or not). Better performance has been observed with the ``opengles2`` driver (use ``sa2 --sdl-driver 1``).
