Thank you for the wonderful spreadsheet!
I tried SotN on my N2DSXL, initially I only got about 40+ frames at the initial scenes (play as Richter), no matter what settings I tried (turn off V-sync, frameskip 1/2/3, L2+Clock, disable sound driver...).
I was using a Chinese version (I believe it's based on JPN version), but I also tried USA version, nothing was improved. Then I realized it's a problem of bin vs pbp. After converting the rom to pbp, I immediately got close to 60 frames at the initial scenes with sound!
It's very playable now, though the sound is crappy. But I really like the fact that I can play SotN on 3DS.
I would suggest you to mention "use pbp" as an important tip to improve fps at 1st page .
I also tried the game "Three Kingdoms 2 King Mainland (JPN)", which is a fairly simple SLG game and I easily got close to 60 fps everywhere. But the pbp version crashed.
I am using version 1.7.5 (12/18/2018 nightly build, as the stable version crashes due to a bug in it).
