A Japan-only Mega Drive cart from CRI that is priced above the middle of its group.

Dyna Brothers was developed and published by CRI for the Mega Drive and came out in Japan on 24 July 1992. Sega Pro later reported that a sequel, Dyna Brothers 2, was in development and described it as a big and bright sprite extravaganza.

Before you buy

It came out only in Japan, so the Japanese Mega Drive cart is the one to look for, and it is a different shape from a Western cartridge. A Western console takes it only with an adapter or after removing two plastic tabs in its slot. Among Japan-only carts it sits above the middle.
