For some reason the same byte pattern wasn't found in the miles dll for the S3 game, even though they where identical. Changed the byte patterns to search for the last 2 bytes of the instruction as well and made the conditional jmp instructions, unconditional for making sure mileswin64.dll doesn't close the process when a debugger is found.
