Patching

When applying a patch, you can right click on the title bar of the file choosing dialog for the file to be patched to get a few options for dealing with SNES copier headers.

• Add SNES Header - Add a 0x200 byte copier header to the file before patching if it doesn't already have one.
• Remove SNES Header - Remove the copier header from the file before patching if it has one.
• Add/Remove SNES Header - Add a header if it doesn't have one, or remove the header if it already has one.
  • This option is useful in cases where you've already tried patching without caring about the header and found it didn't work.
  • In which case you can just use this option on a fresh copy of the file without having to figure out if you need to add or remove a header.

Creating a patch

When creating a patch, you can right click on the title bar of the original or modified file choosing dialogs to get options for dealing with SNES copier headers.

• Add SNES Header - Add a 0x200 byte copier header to both files before creating the patch if they don't already have one.
• Remove SNES Header - Remove the copier header from both files before creating the patch if they don't already have one.

Note that the logging and file registration options are saved to the registry.
