RetailOS Options

OSOS has some 'secret' options that you can enable by placing files into iPod_Control/Device.

The following table shows all known options, with information on what device are they supported. Some of these appear to have no cross-references in q3k's decompilation, but that might be a tooling issue. Ideally, we should test every single one of these :).
