Before you buy
Among Japan-only carts its loose price sits near the bottom, and the risk of a fake is low. Sega Retro lists it as supporting the Mega Modem. Japanese cartridges are a different shape from Western ones and do not fit a Western console without an adapter or removing two plastic tabs in its slot.
