Technical 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.

No BIOS or firmware files required.
