Civilization III complete

[brinf1]

I think I already know that I'm sunk, but thought I'd post my problem anyway. Just bought Civ III complete here on Steam. The game won't launch, gives no error message, nothing - and I think I know the reason why: Civ III is one of the few games I'm aware of that tries to start the first time in 1024x768. I game using my 50" widescreen HDTV as a monitor, which has a native resolution of 1280x720, and won't run games in 1024x768, even in a window. This hasn't been a problem because of the hundreds of games I own all will run in 800x600 or at 1280x720 if they support widescreen or can be tweaked to support it (many thanks to this site for the copious amounts of help I've received!).

My question is - does anyone know if Civ III can be run at 800x600? I've tried the keepres=1 in conquests.ini to try to force it to run at 1280x720 (my desktop resolution) but it doesn't work, and my research here tells me that 1280x720, for some unfathomable reason, is virtually the only desktop resolution Civ III won't support. My monitor, being a 720p TV, won't run any higher resolution than 1280x720.

Any help would be appreciated, if only to confirm that I'm screwed.

I don't know if it's case sensitive but try "KeepRes".
