These patches modify programs to work properly on BackBit (and often improve them on other systems as well).

The file format is as follows:

[APPLICATION_NAME] . [EXTENSION] . [MD5 of original] . [PURPOSE] .patch
[APPLICATION_NAME] . [EXTENSION] . [MD5 of patched version] . [PURPOSE] .unpatch

- Application name is simply the title of the particular release with no frills.
- Extension is often a standard C64 file extension, such as D64, CRT, PRG, etc.
- MD5 sum is created from the original file with the commandline tool "md5sum".
- Purpose is a brief summary of what the patch fixes, or what was wrong, i.e.:
  * audio: there was a problem with audio that affected some machines
  * autostart: the program did not start automatically with LOAD "*",8,1
  * kernal: the program was not compatible with standard KERNAL vector loading

To apply the patch, first verify that the MD5 matches your original file (using "md5sum") and then run this command:

  bspatch source.ext patched.ext filename.patch

To qualify for this repository, the patched version must be the same file extension as the source,
and must be under 1KB, proving that it is just a patch and does not contain copyrighted material.

Patches must also have "unpatches" that will revert a patched version to the original, for posterity.

To generate your own patch, use the "make_patch.sh" script, follow the above rules and regulations, mail it to me at

and I'll be happy to post it here once it's verified working.
