Hi there!
Yeah, glad the scale settings of the Dragonboones worked for you! RPG Maker is strange sometimes, is best if you do everything from "inside him". If Dragoonbones has this option, go for it!
I think there are some plugins to fix the blur and remove the outline of the fonts. Try to search on the Sigma Succour spreadsheet. I tested some on MV a while ago, but it didn't fix my issue. I just manage to get a pixel-perfect font it using a Bitmap Font plugin, and by the way, I have one.
But I also know that someone else did other. It's on the Sigma Succour spreadsheet too!
