Gunboat 1.2.4

Smoother gun views: the side of the boat now moves with the view.

You still need your own copy of the DOS game. Unpack the package, copy the original files into its Game folder and start the game: gunboat.exe on Windows, Gunboat.app on macOS, ./gunboat on Linux. The README.txt in the package has the details.

Fixed

• The side of the boat in the gun views (enhanced picture): when you turn a gun towards the boat, its side comes into view. It used to come straight from the original's low-resolution picture, stepping along 15 times a second while the world behind it moved smoothly, so its edge seemed to jitter and the picture could stutter. It is now drawn at full resolution and moves together with the view. It matches the original's own drawing exactly at the original size.

Checked

The game's own code is unchanged since 1.2.2, where every ported function was verified against the original machine code (359 differential tests, 193,273 cases, no differences).
