The MOH Widescreen utility allows you to quickly set and use your system's native resolution or any custom resolution you want for MOHAA, MOHSH, and MOHBT.
The .NET Framework 2.0 is needed in order for this utility to run. Runs on Windows XP and up. Simply double click on the executable, and set your MOH resolution. Start the game. You're done. No editing of config files manually. This does it all for you.
