Baseline (Widescreen) Solution & Issues
The Game offers only 4:3 resolutions - you need to use a modified EXE and a dgVoodoo 2 Wrapper to get it HOR+.
I Hex edit a modified Win7 EXE which works also for Win10x64 - use the Attachment Messiah - Widescreen.7z
and select your Aspect Ratio. Also extract the dgVoodoo 2 Wrapper dgVoodoo2_53.zip and copy the content from MS Folder to your Game DIR.
You have to start the Game from the MessiahD3D.exe and select you resolution.
For the safe side i have all Files in the Attachment - just copy it into your Messiah Game folder and overwrite everything.
