In depth

A closer look at PatchIt

The PatchIt application was designed to be a small file byte-patching utility. This is driven by a simple scripting language. It can patch sequences of bytes in any file, search for byte patterns (with wildcards) and also extract and utilise DLL exported function addresses as source positions in files to be patched.The total command list is as follows:MESSAGEDisplays a message during script execution.DIROptional directory path to search for files. For compatibility it is advisable not to use specific drive names in the path.FILE [filesize]Filename to patch. Optional filesize specifies the size that the file must match to be accepted.FIND []...Performs a search on the current file for the sequence of bytes that match ... up to max 256. Use the keyword * to match any byte. If a match is found then the PATCH file position value is set to the file position at which the found pattern begins.FUNCTIONSets the current patch position to the file position of the given exported function name (case sensitive). It is assumed that the file being patched is a DLL.PATCH [[POS ] | [OFFSET ]] ...Patches the current file at optional file position/offset. Replaces orig_byte with new_byte. Fails if original byte read from file is not orig_byte.COPYCopies "orig_file" to "new_file"DELETEDeletes the specified file.INIFILESpecifies an INI file to be used in subsequent INI commands. This filename is relative to the last DIR directory path.INISECTIONSpecifies an INI section name for use in subsequent INIWRITE commandsINIWRITEWrites the given string value to the INI keyname in the previously specfied INI file's section.
