The system is: if you uncheck Advanced Settings, some settings are set to default, some not.
For example, "drive speed" is unchanged, but you need to be in "expert" mode to change it.
There is a reset button to restore all advanced settings including, for example, drive speed (to slow).
Fullscreen uses the safe "fake fullscreen" mode:
With so few options, hard to blunder!
Display options far simplified!
Sound - by default we use the new MAME-like emulation.
Machine: Mega ST4, LaceScan, Extended monitors, Alt-RAM etc. need advanced.
Wake-up is random, you can select or "disable" in expert mode.
This will certainly change again.
