Here's another RAR file with an IPS patch and table files: Link
I got the elipses and tilde in there, but I had to make the elipses 16x16. There's just no way to squeeze all three dots into one 8 pixel wide character without it looking weird. The new elipses works just like the original 16x16 elipses, only it's 5 through 7 instead of 1 through 4. The tilde is 8x16 and works just like the other 8x16 characters.
I replaced the underscores in the story mode intro, but I stopped after that. I think there might be some formatting issues since I think you were expecting an 8 pixel wide elipses, and I'd rather let you decide how to handle that. At least it's better than having to use three separate periods.
I did notice that you ended up with at least a couple blank pages. I'll look into how to skip them. Is there anywhere you could really use an extra page? Once I figure out how to skip them there's a good chance I'll also be able to repurpose the blank pages elsewhere. Of course if it's not needed that's fine too.
I replaced the round clear "CLR" with 8x16 "CLEAR", and got that delete/cancel text sorted out.
I also fixed the problem with VS mode that I mentioned. It shouldn't break again.
I've also had issues reinserting one of the compressed files - seems to be too big, for some reason. Not sure why.
It's not exactly crucial, but for completeness' sake, this is much better than the 16x16 version. You'll see the screen if your emulator is set to use a SNES Mouse or other peripherals.
Uploaded the uncompressed .txt here.
I can probably get this working, but I think you uploaded the wrong text file? It looks like it's the 16x16 version, which is already inserted and working.
Still working on the English-only naming screen. I've made some progress on it, but none of those edits are included in the patch.
Just for fun here's a photo of the game running on an actual SNES:
