Help! Castlevania DoS 99.9% map completion (screenshot inside)

First pic is 100% map, second pic is my 99.9%. Apparently I'm missing one room but I've stared at these for a half hour and can't find what I'm missing. Anyone want to take a shot?

EDIT: So this is bizarre. My save file in the Abyss (after clearing the game) shows 99.9%. When I go down to the warp room below it, still shows 99.9%. As soon as I press UP to warp, it jumps to 100%, whether I jump back to the castle or stay in the Abyss. I guess I'm not missing a room, but that sure is odd.

If you ever run into this issue again with another castlevania, you can use a photo editing program that supports layers (e.g., photoshop, paint shop pro, etc.) and have the complete map be one layer and your map (resized to match) to be another layer. From there you can make the top layer transparent or us some sort of difference effect to highlight the differences between layers.

I've done it many a time being a completionist for metroidvania games.

Great tip. I've been doing it the poor man's way: Opening each image in a separate window and alt+tabbing between them.
