How to access the original setup-program of Illusions? There seems to have been some sort of tutorial videos but they've been removed.
You can start the Illusions-bat with parameters to enter Setups.
In the Conf use one of the following Lines in the autoexec-Part:

call illusion (start the Game normally)
call illusion s (start with sound setup)
call illusion o (start with gameplay-Options)
call illusion so (start with gameplay-Options and sound-setup)
In Fantasies and Dreams I can enter an option screen and change the keys that are used.
Illusions had side nudge as well as forward nudge and I think it was with the alt keys but
somhow my config is messed up and now I have one left side nudge and forward.

running the Launch Settings doesnt let me map keys :(

Can you explain more clearly where and what I edit to

"call illusion o (start with gameplay-Options)" and will that give me the options to edit key binds?
