How many pressings of Ultima IV were there?

[Sean Gugler]

I've been analyzing some disk images found on the web. None of them have iron-clad provenance, but I believe they show circumstantial evidence of at least 4 revisions during their 1985 production runs.

 

Briefly, it looks like:

1. first release
2. fix shop sell-back award to match advertised price; tweak pub keywords and dialogue with Presto
3. numerous text fixes; move Shamino away from Ankh; prevent X-it from a flying balloon
4. dungeon fixes; Lord British dialogue fixes

 

Have a look at my in-depth report, with justifications for why I believe these were retail updates and not after-market hobbyist patches:

I welcome supplemental or contrary evidence! Especially any disk images that can be solidly traced back to a confirmed retail pressing, untampered by crackers or modders.
