Apatch

Apatch was developed to be a byte-patch generator. It is a tool which compiles a simple script into a patch executable. apatch can create multi-file patches with search/replace, backup creation, and crc checking.

The patch executables created are Win32 GUI programs. They display a dialog with a status window which is used to show information to the user. A very light encryption is applied to the patch executable in order to keep total lamers away.

These are the command-line arguments for apatch:

Syntax: apatch [options] [output file]

Options: -d debug script -v show version information

'apatch -c ' can be used to calculate the CRC of the given file. So basically you have to write a simple script file, which contains the information about what files should be patched and how. The next sections describe the format of the script file and what commands can be used -- also check the examples.

The switches can be given anywhere in the argument-list, in any case and in any order you like. Input- and output file should be pretty self-explanatory. The switches work like this:

-d : Makes apatch output what it has read from the script. This is nice for debugging.

-v : Displays version information. The command switch '-c' can be used to calculate the crc of a given file. This can then be used together with the crc command.

If command-line tools make you nervous, you can try apatchUI, which is a simple GUI wrapper.
