I'm playing this game on my 16:10 full-hd monitor. Just a heads up that the game does *not* allow selecting this resolution in the game options. (for reference: 1920 x 1200)

However the resolution can be manually adjusted in the appdata/roaming directory, and it will then run.

It runs fine in proton provided the .wma files in music are deleted or converted.
I've simply plugged in the soundtrack shipped in GOG and was good to go.

Regards

Yeah, the game was still made when screens were still square.

Try setting the resolution directly via the options.txt file.
