Blue MP Digits patch?

I'm also having trouble with this file, but it's only because of my ROM.  Does anyone know what the actual changes are or have similar problems?

Do you know how to use a debugger? Setting "execute" breakpoints on those offsets would make you see the code, use "read" breakpoints if you think the changes are palettes data. Use "step in" to see one instruction at the time. If you're unfamiliar with all this it's a nice time to learn, the person providing you the answer would likely do the same anyway.
