Works perfectly !
This is only guaranteed to work on original system, should work on 90% of clone consoles BUT I DO NOT guarantee functionality on none of them. I know for sure it will NOT work on a RETRO FREAK and RETRON 5.

THIS INCLUDE MEGA MAN X, MEGA MAN X2, MEGA MAN X3, MEGA MAN 7, MEGA MAN AND BASS, MEGA MAN SOCCER AND MEGA MAN X3 ZERO PROJECTS V.46A

TO SWITCH BETWEEN GAMES YOU NEED TO HOLD RESET FOR 2-3 SECS ON ORIGINAL SYSTEM, IF YOU USE A CLONE CONSOLE AND THE RESET FUNCTION DOES  NOT SWITCH GAMES YOU CAN USE A FRIDGE MAGNET TO DO SO. YOU CAN CONTACT ME IF YOU NEED HELP WITH THAT.
