notes: |
  Libretro port of Jump 'n Bump, a multiplayer bunny-stomping platformer
  originally by Brainchild Design (1998). Released as freeware under GPL.

  The core loads a .dat archive file as content via retro_load_game().
  All game resources (sprites, sounds, levels, fonts, music) are packed
  inside the .dat file. No system directory files, BIOS, or firmware
  required. The .dat file is built from the data/ directory by the
  jnbpack tool in the upstream repo.

  Extra levels are available from brainchilddesign.com as additional
  .dat files.
