I took this game out recently as i have never finished the game before when i had a regular CRT, now that i had a widescreen I thought this game would look even more sweet than before (and it does ) . Now this is an old game so I knew it wouldnt have widescreen support but I found a way to get it widescreen through the registry. I came here before figuring it out to look for a solution but didn't find one so I will post one for everyone.

Go into the registry editor

Go to:
HKEY_LOCAL_MACHINE/SOFTWARE/Digital Reality/Haegemonia

To input a resolution for example 1680x1050:

ResolutionX = 1680
ResolutionY = 1050

I have noticed that if I go into the options/load menu within the game, these registry values reset to 800x600. Now this means you will have to change these values before playing the game everytime IF you went into the options/load menu previously playing the game.

I know this isnt a FULL solution but atleast you have widescreen
