BlockBoy Arcade

Arcade machines with full gameboy resolution and color support!

Fully server-side, using polymer! Checkout polymers authost feature to host the resource-pack (in polymer/resourcepack.zip) automagically!

There are no recipes, use /polymer creative to see the items or use /give @s blockboy:arcade

The mods' builtin datapack comes with 6 open source gameboy games:

Config

{
  "dateFormat": "dd.MM yyyy, HH:mm",
  "sound": false
}
  • dateFormat: Date format for rom save data tooltip
  • sound: Flag to enable sounds for the playing player using simple voice chat

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/<namespace>/blockboy/<rom>.gb and data/<namespace>/blockboy/<rom>.gbc Make sure the rom file names are lowercase and only contain letters from a to z, 0-9 and/or underscores.

To add your own arcade model item + block use the filament mod and the blockboy:arcade behaviour for decorations.

Arcade example for filament (data/<namespace>/filament/decoration/<name>.json):

  "id": "blockboy:arcade",
