I want to modify the behaviour of an old DOS game called "The Manager" (aka Bundesliga Manager Professional in Germany). I want to modify the points assigned to each team when the team wins a match in the main tournament.

In the original program (the italian version) two points were assigned to the team that won. Now the rule is changed, I can update the game with its official editor, but I can't modify the rules that are stored, I suppose, in the main binary.

How can I monitor the execution of the game and discover which parts I need to modify?

At first I discovered a debugger for DOSBox, but it is not compatible with macOS, so I have to come back home to test the quality of the real time debugger of DOSBox.

With the old Commodore 64, I used XMon or some cartridge that enabled the user to read and write directly to the memory.

Is there a method I can use that will help me find where to make these changes on macOS?
