Stronghold Decompilation Progress
Almost done recovering the data files.
That was really tedious...
Remains saving sprite sheets as *.LBM, instead of PNG.
Then the grab process should be working again.
That will allow easily decompiling the stash functions.

Recovering unit sprite sheets was involved.
The game has a set of hardcoded agent archetype structures.
Each references a hardcoded animation table.
Each agent variation can have up to 6 sprite sheets:
three races, two genders.
Ghidra structure support is top notch.
Compared to IDA Pro, you can just define the areas you care about.
