# NGPC–Dreamcast link cable: reconstructing retail game uploads

> The NGPC–Dreamcast link-cable project reconstructs serial exchanges between SNK vs. Capcom: The Match of the Millennium and Capcom vs. SNK: Millennium Fight 2000. A beetle-ngp patch and Python bridge connect RetroArch to Flycast's BattleCable interface; protocol notes and byte logs document the upload sequence. The author reports successful retail transfers in emulation and a prototype transfer to a homebrew responder on a real Dreamcast.
