You dont need to hex edit anything to add support for your stock bin.. Its an open JET db4.0 file that drives DHP so you could add it there if you knew what codemask it uses... Its not really worth the effort because you can just use one thats unlocked... I hardly ever run the "right" osid for a car because all of the latest updated files are availible on DHP.. you typically want to run the newest code you can because of all the bug fixes done over time.. its like why run windows 3.11 when you can run windows7 on the same machine.
