I'm run off my feet at present. Probably end of the month.No, I don't have that patch. Are you sure it exists? I have a copy of what is supposed to be the final version of MM3, the one included in MM6 Limited Edition. That cures a lot of the bugs in MM3 (including (from memory), the unintentionally missing Greek Brother, and the four positions just north of the Tomb of Terror that used to lock up the game), but it didn't cure the ageing caused by those crystals, and it didn't cure the erroneous computation in Arachnoid Caverns.
I also still have the v1.0 game installed somewhere on one of my drives, but I don't usually play that one.
