notes: |
  Game Boy / Game Boy Color emulator by GIGO and Hii with link cable support
  for two units side by side. Libretro port based on shinichiro.h's SDL port.

  cpu::reset() initializes PC to 0x100 and sets post-boot register values
  (AF=0x01B0 DMG, 0x11B0 CGB), bypassing the boot ROM via HLE.
  No system directory access, no file I/O for firmware.
