.BDF File Association 4

Patch format used to update video game ROMs; may also be used to produce patches for binary files.

More Information

Patching is commonly done to video game ROMs for one of two reasons. One reason is that the user wants to play a game in English that wasn't originally created for English users. The other reason is that the user wants to alter gameplay, such as the level order or character dialogue.

The bsdiff/bspatch tools can be used to create and apply BDF patch files:

  • To create a BDF patch file that makes your desired goodfile.123 from your original badfile.123, type bsdiff badfile.123 goodfile.123 patch.bdf.
  • To apply a BDF patch file to your badfile.123, which subsequently creates your goodfile.123, type bspatch badfile.123 goodfile.123 patch.bdf.

NOTE: The .BSDIFF file extension may also be used instead of the BDF extension but it is less common.
