I think someone will do it. You can ask them directly on their posts.
I had played Cold Steel III PE on Switch and experienced many bugs awa framerate issues in some locations, but still completed it before hacking my Switch and knew about the FPS patch (which came out right after I finished my first playthrough last year).
I just finished my second playthrough of CS3 and transfer it to CS4. So far the cartridge runs pretty well without issues (still need an update, though).
For the performance, I don't have any problem enjoying CS4 without 60FPS or modding resolution.
