The pchtxt can't contain numerous @stop entries, as that tells it to stop parsing the pchtxt entirely. You should remove all but the last @stop command, then the mod will work properly in Ryujinx.
Outside from having to fix the pchtext, the mod works pretty well in both Ryujinx and in yuzu.
Towards the note: It would be a good idea to look into the SSBU Skyline environment, adapting that to TOTK, and using it for patching in dynamic FPS.
