Baseline (Widescreen) Solution & Issues
Changing game resolution
Normally the game can only be opened with these resolutions:
320x240
512x384
640x480
800x600
1024x768
You can use custom resolutions by making a shortcut to "bblit2.exe" (in bin folder) with these arguments:
/x - width
/y - height
/win - windowed mode
/skip_intro
/opengl - 3D acceleration mode

You will need Cheat Engine.
Download the Cheat Engine table from the files available from the PC Gaming Wiki Community Files (search there) and change the Horizontal FOV. The value varies for each aspect ratio. (Default [4:3] = 50)
2560x1080 (21:9) = 25
1920x1080 (16:9) = 35
1920x1200 (16:10) = 37
There might be pop-in due to culling. Particles are still stretched.
