Adding roms / items
You can either add cartridge items using filament or just use the blockboy:rom component to give yourself an item that can play a given rom file: /give @s paper[blockboy:rom="namespace:game.gb"]
Put the roms in `data//blockboy/.gbanddata//blockboy/.gbc
Make sure the rom file names are lowercase and only contain letters from atoz, 0-9` and/or underscores.
To add your own arcade model item + block use the filament mod and the blockboy:arcade behaviour for decorations.
