The RPG Maker files are scaled up to fit MZ/MV's default 48px cells, so they're ready to use in RPG Maker. The original sprites and tiles are 16x16, and I've upscaled them so they sit naturally in the default grid without any extra setup.
Thanks, that answers it. 16 to 48 is an exact 3x, so the pixels stay square in the default grid.
Exactly~~~
