Many of the Hatari debug options can be enabled only from command line, 
they cannot be set in the configuration file:
https://hatari.tuxfamily.org/doc/manual.html#Debug_options

Reason for this is that typically their use is temporary.


NatFeats use is not any more limited to debugging, therefore it can 
nowadays enabled permanently in config file.

=> Should it move from Debug to General options section?


Note that there are also many options that can be set only from 
configuration file(s), not from command line.  E.g. most Debugger and 
LILO options are such:
https://git.tuxfamily.org/hatari/hatari.git/tree/src/configuration.c#n47

(Offering them all on command line would complicate / clutter the 
options output too much.)


And what options are visible through different Hatari GUIs (SDL, Mac, 
Python/Gtk) and its control socket & fifo interfaces differ again a bit.

(All command line options can be used through socket / fifo interfaces, 
so they're superset of that.)
