This is actually pretty good though i have to ask does this work for MV or do you have something else similar too that?
Hi, the [CGMZ] Mailbox plugin is only for MZ, I do not develop for MV any longer.
But the letter graphic assets can be used in any engine, they do not have to be used in my MZ plugin I just had them made to help ease the art requirements of picking up my plugin. You could use the letter graphics in MV if you had a place for them in your game.
