But right now I'd like to repack a file after having done some modifications. is there a way/tool/option to do it quite simply ?
Thanksfully

This tool currently doesn't do that but it is possible if someone continued reversing. My gut says it be rather risky repacking / installing the modifications without understanding some of the unknown bytes as there's a non-zero chance they could be checksum related
