You need to have a spritesheet that you can replace with Boyfriends current spritesheet. When you get the sprites, make sure that your sheet has the same name in your files as the sprite sheet name for original Boyfriend. Lastly, copy your gacha spritesheet and paste it into the files of the Gacha Mod.
