# Applying a patch or crack

MS-DOS games often received patches to fix bugs, and cracks to disable copy protection. These usually come as sets of files that replace some of the original game’s files. To apply a patch or crack to a game:

1. Show the contents of the game’s gamebox in Finder.
2. Browse the C.harddisk folder to locate the folder containing the game’s main program(s).
3. Drag the patch files into this folder to copy them into the gamebox, replacing any existing files.

4. If the patch came with its own updater program (called “PATCH.EXE” or similar), double-click on the program to run it and apply the update.

   If the program extracts more files of its own, check if they include another updater program: if so, run that too in the same way.
