Hmm... if you don't mind me asking, but would a VWF be beneficial in FF4? I'm not 100% sure I know what a VWF is, but I assume that make for a bigger (vertically wide?) font?
Seeing as the J2e translation was noted as using one, I went ahead and tried it out. The font it's in using in the texboxes just seems super huge compared to FF4us's vanilla font (which imo was already big).
If you're looking for a different font because you're trying to make it look more like the WSC edition (or just don't like FF4's font in general) I've got some screens up on my Slick thread of a font I've been working on. It's neither VWF nor is it the font from FF4WSC (hell Idk if it was ever in english), but if you're interested I would be wiling to share it with you.
Bear in mind it has a LOT of squish tiles to it, but that's just for squeezing as much text into battle messages/item descriptions/names of spells and enemies/Items/menus. But it's also a much skinnier font, it technically almost never looks "squished" in that sense.
