I coped with character type coversion to let it looks like c type, and search bytes from
*.dll to modify it.
so, there is sth I learned and written down here.
def hex_read(filepath: str) -> bytearray:
dll_data = hex_read('D:\\test\\test.dll')
Find bytes and replace it:
index_start = dll_data.find(b'\x85\x69\xf0\x7f')
