Please add more support for Tomodachi Collection

I tried editing some BMG files for Tomodachi Collection and tags such as "{{1:10 arg="0x0000"}}" seems to be overwritten in game, even if you edit a single character of the file and save. All the text seems to be in random colors, stretched, and have the little ? box in place of names or items. I could have sworn this didn't happen in earlier versions, but I might be wrong.

The overall file format is a "bMID1" if that helps. Thank you for reading my request in advance.
