ngp-link: reconstructing the Neo Geo Pocket Color link cable

ngp-link reconstructs the Neo Geo Pocket Color serial link cable and uses the recovered behavior for browser netplay. A hardware sniffer, ROM disassembler and headless emulator compare real traffic with game link code. The documentation covers UART framing, BIOS COM calls, handshake states and games that drive the serial chip directly.
