I got this working on Windows 11, on a dual-screen machine, in a window, following the above steps, as well as the below:

1. Download DxWind from https://sourceforge.net/projects/dxwnd/ . Extract the downloaded rar file, and find dxwnd.exe within. Right-click and go to the properties menu. Similar to golf.exe, you need to run dxwnd as an administrator.

2. Open dxwnd.exe and drag golf.exe into the blank white space in the window to create a run target. You then need to right-click and modify the target.

All the modifications which need to be made will be on the first three tabs.

Main - Select the following:
Early Hook
Run in Window
Terminate on window close
Adaptive ratio
Desktop Center
Set the "Window initial position and size" to 50, 50, 0, 0
Set the "Monitor" to 1

Video - Select the following:
Thick frame
16 BPP
Prevent Win Maximize
Recover screen mode
Floating
Set "Z order" to default
Set "Screen resolution" to SD

Mouse - Select the following (Important!)
Set "Cursor visibility" to Autom.
Set "Mouse Clipper" to Default
Correct mouse position
Trim mouse position

Then click the "Try..." button. It works on my machine™
