You might find a font nerd who knows exactly what it is, and then you experiment with sizes until you get it to match. But honestly, it might be faster to just create your own version of the sheet with the new word. I mean, it would take, like, a few minutes
Doing clean-up on tall-ified sprites, filling in pixel by pixel where the stretching warped the image, feels incredibly tedious but also highly rewarding when one zooms out and the sprite looks even better than before.
I'm going back to the default RTP, in the interest of getting it done. FSM is lovely but slow to work with and has tall doors. And switching to tall sprites would mean a lot of franking, and also the horses will be small.
