A CCS script to change the font to any of the available fonts in EarthBound

Font_Changer.ccs

import asm65816
import asmref

/*
	This modifies the CC_1F control code tree, this will add [1F 32], [1F 33], and [1F 34] so that you can switch fonts. This will mirror what you will see in the Font folder so that:
	[1F 30] = Normal Font
	[1F 31] = Saturn Font
	[1F 32] = Big Font
	[1F 33] = Battle Font
	[1F 34] = Small Font
*/

//+-+-+-+-+- CUSTOM COMMANDS -+-+-+-+-+
/*
	You can call on these instead of just typing in the control code. This should be similar to how CCScript does its fonts like "font_normal" and "font_saturn".
	
	REMEMBER TO IMPORT THE FILE FIRST, THEN YOU CAN USE THE COMMANDS
	Alternatively, you can use the control codes, but for the commands, import the file.
