TerminalFury: An OpenGL Terminal Velocity, Fury3, and Hellbender source port.
Not open source but the dev is looking for help, mostly with OpenGL stuff. He always sounds so tired on his update videos.
Should work fine on Linux and the Steam Deck through Proton. 'Terminal Velocity: Legacy' was available on Steam but I don't think the 'Boosted edition' will work. Fury3 and Hellbender I think are abandonware.
