All Solaceon Ruins rooms are identical, so there is no reason to have
them duplicated.
All the Old Chateau rooms are similarly identical, EXCEPT for the lone
room that can spawn Gengar. I also left the Rotom room in, for when I
get around to adding event encounters.
Finally! Location order is the same as from the old dex, which was
something like the game but ultimately arbitrary, so it's not any better
now.
This takes a very different approach to storage, rather than copying the
game exactly and trying to fix everything in code. Comments coming
shortly so other people can actually make use of this.
