Trying to reverse old game animation file (Ultima Online)

[Killroth]

Hey guys,

I've been stuck trying to reverse an old Ultima Online animation file called animationsequence.uop.
It seems the UOP format is a container that holds normally a collection of mul files, however, for this animationsequence.uop file,
it containers 4 blocks and 354 total sequences in the .bin format.

Is there anyone here who could help me decode these bin files so that we can reverse engineer these files and use them in our custom clients.
We would likely need the offsets, pixels, x, y animations, etc.

The images themselves can be seen in game.

I have included the UOP file as well as a UOP Unpacker where you can view all the blocks as well.
You would just open the solution and run the program itself.
You can mouse over the options in the UI for labels of what the buttons do.
