Technical 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.
No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
