I'm trying in rpg maker xp and only have those 3 foldersDifferent for each one.
For Ace for example most of the time it works to just open the game in the Ace editor, go to scripts, Main, and add this line
Font.default_size = 18
(Ofc replace "18" with the size you want.)

I can't find the scripts in there. any ideia when i can find them?
Ps: theres nothing in the fonts folder.
