500 In 1 DIY 72 pins 8 bit Game for NES with game Contra 7 NINJA GAIDEN DOUBLE DRAGON NINJA TURTLES 3 90 TANK SNOW BROS alien 3

Description

Works perfectly on an original NES system, Retron systems 1 through 4, and the Retro-Bit systems. Please note that this will not work on the Retron 5 due to the way that system emulates games. Additionally, there are some games which may have some Japanese text or use the Japanese title.
