Hacking a binary file

I've been trying to hack a binary file.

The first two bytes in the file are a checksum - I think.
The next set of byte pairs point to text strings in the file. I've sussed these out.

However, even though I can find the first input screen on the hardware device that "runs" these files, I can't work out where the hardware device is getting the location of the first byte of this input screen. It's probably using an offset from a known location within the file, but my brain hurts trying to figure it out.

Anyone wanna help? :)
