Hello, I just bought the game, I want to play it in fullscreen with no black boxes, but no matter the setting, game just seems to ignore ratio of set resolution and scales back to 4:3 even in windowed mode. My gpu is radeon 6670, native resolution of my monitor is 1440x900. What should I do to make the game scale using 16:10 ratio? I tried searching the forums here, also setting gpu scaling in catalyst to on/off without success.

backup your dosbox.conf for your Orion file, try to change screen settings, if something wrong just revert to old conf file.

or

You can still launch the game in 640x480 mode (right click propierties => 640x480, works for windows don't know on MACos)
that should increase the box size,
