Is it possible to convert file hex position to cwcheat

[vsub_]

The reason.

The game Dead Head Fred is not working since 0.8.1(excluding)and the reason for it is the first tinny video after the memory stick check(the same thing as with Naruto Shippuden Ultimate Ninja Heroes 3)

The simplest fix for this is to just replace one byte to make the video to not work(which will add to console an error "Bad PSMF magic")

Position in the image
0x17003800 - 0x170C6FFF
Replace the 50 with 0 at 0x17003800 and this will make the video to not be loaded and make the game to work.

Is there is a way to apply that change by using cheats rather than modifying the image?

If some dev is interested in the video,here(I extracted it from the DATA.PAK file)...it's pmf file
