Baseline (Widescreen) Solution & Issues
Use the Aleph One port Widescreen resolutions are listed natively in-game or can be set manually in Marathon Preferences located in %LOCALAPPDATA%\AlephOne (this file is made after running the game once). Everything has the correct proportions for all aspect ratios.
For a Hor+ field of view do the following:
- Go to Scripts in the installation folder.
- Make a new file called FOV.mml
- Add this line: <marathon><view><fov normal="120" extra="160" tunnel="70" /></view></marathon>
- Replace 120 with whatever FOV you want.
Extra and tunnel are FOV settings used for the extravision power-up and the tunnel-vision mode; extra should be higher than your normal FOV while tunnel should be lower.
