if you mean sms model 1 both the rf switch and the original power source form genesis 1 console work fine on the sms, also the a/v pinouts are the same so you can use the same a/v cable (with the male 8 pin in it) from the genesis 1.
the power source tip is thicker on the genesis 1 and SMS 1 and the polarity is the same
nice gaming
by any chance do you know if the nes zapper can be modified to work as
a sega light phaser for the sms?
