The Dosbox emulator, a popular tool for running old DOS games and applications on modern operating systems, has a built-in debugger that can be useful for developers and enthusiasts. However, using this feature requires some setup and configuration, which can be challenging without proper documentation.

One of the biggest hurdles to getting started with the Dosbox debugger is building a version of the emulator with the feature enabled. This process is not well-documented, but it's essential to create a release build instead of a debug build, as the latter can interfere with the debugger functionality.

Fortunately, Mac OS users can install pdcurses using vcpkg and manually edit the config.h file to enable the desired version of the debugger. Building a release configuration is then necessary to ensure that the debugger works correctly.

For Linux users, installing ncurses development packages via their native package manager is required, followed by creating a release build with additional configure flags such as -enable-debug or -enable-debug=heavy.

Despite its potential usefulness, the Dosbox debugger feature is currently considered broken and not well-supported. However, contributions are welcome to improve the documentation and fix any issues that may arise during usage.

To get started with the debugger, users must first build a version of Dosbox with the feature enabled. Once this is done, pressing Ctrl+F1 will bring up a keymapper, where a new action called 'Debugger' can be remapped to another key combination. This allows users to customize the behavior of the debugger to their liking.

Unfortunately, pre-built versions of Dosbox with the debugger feature enabled are not available from the developers. However, there may be community-created builds or patches that include this feature, such as dosbox-staging builds with debug enabled.

Overall, while using the Dosbox debugger on Mac requires some technical expertise and setup, it can be a powerful tool for debugging and optimizing DOS applications and games. By following these steps and contributing to the project's documentation, users can unlock its full potential.
