btw.. I`ve spotted in manual that in this game exist some options... well.. where ? :) On title screen i`m seeing only four flipper names and info.. nothing more.

Are you sure you have the right manual? Reading through the Pinball Illusions I could not found any options menu. You can choose between high and low resolution although this option seems to be deactivated in this GOG-release (onligh high res available).

This also means that you can't change the number of balls for your game.

And here is the thread where to download the manuals:

For Illusions.exe use /? to get a list of available command line switches

you can use /o to specify options.

An example for the autoexec part of the DOSBOX config file is:

@D:\ILLUSION\ILLUSION.EXE C:\ILLUSION.CFG /o

Then you should be able to set screen resolution, viewing angles, number of balls.... you will want to save settings when done.

You may also want to back up the original settings.

For audio card config see other posts about audio

If you want higher resolutions to work you can try fiddling with newer dosbox svn -- I used svga_paradise or viewing the official dosbox site for compatibility options
