vpatch (genpat) without CRC check

Hi. Anybody help plz.
Is it possible to make patch with no crc (or md5) check of source files, which will be patched?

How will that work exactly? The patch converts a certain file to another, you can't skip checking the converted file is the file you expect.

If you want to change just a certain location, without a patch, you can use FileOpen, FileWriteByte and FileClose.
