How do you edit the text in these like that?

Idk how they do it. Besides, I found this image online. But we can assume that the person who edited this image used an image editor to erase the actual text, and type over the now blank text box using the PMD EOS font.

I know about an Undertale dialogue box creator website. I'm not sure if there's a pokemon mystery dungeon option on there but I havn't seen one.
