notes: |
  Game Boy / Game Boy Color emulator forked from TGB Dual (Hii, 2000-2004)
  via the libretro port tgbdual. Adds multi-Game Boy emulation with link
  cable support for up to 16 players, DMG-07 4-Player Adapter emulation,
  infrared peripherals, and built-in Pokemon distribution events.

  No boot ROM support. cpu::reset() sets PC=0x100 and post-boot register
  values directly (AF=0x01B0 DMG, 0x11B0 CGB). The core does not access
  the system directory and loads no external firmware files.
