I really don't believe the Golden Cricket Cage half-pendant was in the Wall Climb. John and Tia spent a lot of time in that room, and I think we would've saw it for sure. Plus, there were a lot of unentered rooms in that run the last guard could've been practically anywhere. Going by Kamehameha and Great Seal's layout, the last guard was probably in the Tomb of the Ancient Kings. I would say the half-pendant was in the Shrine then?
Silver Saddle Horn's half-pendant is tricky because the last guard could've been in the Gargoyle Room or Well. I say the last guard was in the Gargoyle Room because it was pretty uncommon for a Season 1 run to not have a guard in the entrance room. And that would've made the last guard in the Holes of Python judging by the fact the Treasure Room did not open to the Holes of Python. I need to go back and rewatch this episode again though. The Heart Room was probably the location for the half-pendant.
Not sure about the other ones. Runs like Golden Cup, Stone Marker, Shaka Zulu, and Geronimo had some pretty bizarre paths where it was hard to tell the true intended path. Plus, Season 1 was inconsistent with their hiding places. They practically hid the half-pendant in the first area that popped in their mind.
