In DeltaPatcher you can choose to apply the patch by ignoring the checksum check. You can at least see if the patch works, after disabling the check.
It does not work after disabling the check. Two emulators refuse to run it.

You have 2 different roms, romA and romB. Make copies of them, then change a single byte in these copies, let's say write FF at 0x1234. Then create patches using xdelta. Now you have 2 same patches, the only thing that should be different is a checksum taken from original roms. And this difference you will see in comparsion, which will point to location where xdelta stores checksum. Find this location in your wanted patch and take checksum from it.

Now that I think about it, there is an easier way. You can make any patch for any rom, and since you know this rom checksum, you can just search for it in a patch
Seems that it would be just as easy, if not easier, to just attempt to run the patch on all these roms I'm collecting to scavange checksums from.

Okay. In this one instance, I figured out that the problem is that the romhacking submission is incorrect & the site does not verify submissions. The article has the wrong checksum listed; another dump worked instead. Wonderful. Gonna be lots of fun trying every possible dump for this folder full of failed xdelta patches I have.
How does one go about reporting this?
