No worries, I am trying out SCEE expert mode, but that will take a while to get used to.

Anyways, did a survey and got some info. The corner address is 200. With the address on the elm side, it is impossible for the 200 address to be on the elm street. This also aligns if looking at the addresses on the side of Avenue Saint-Denis.

So 296 and 298 are on Rue Elm while the rest in that building, including 200, are on Avenue Saint-Denis
