I think the font name and file name are the exact same, but just to be sure it's the font name.
I've...sort of made progress? The script was designed for touch screen menus, and I asked CNG about it and he wasn't really sure either. I'll keep messing with it and see if I can get it working though. The only issue is getting it to use map coordinates instead of screen coordinates. Of course, there's a possible workaround, but it wouldn't be very...good? You could make the sign event turn on a switch (or use variables) depending on the player's location, and use that to figure out what the screen coordinates of the event would be, but it would get messy.
