Thanks !!
Actualy, I did some close study of all the pictures of the several controlers (I am close to getting a Maracas expert
)
The Samba Fans Maracas look EXACTLY the same as the Sega's (apart from the color and sticker). The Cha Cha's look a bit different...
The Cha Cha's control box is small, and the ultrasonic sensors are connected seperatly through wires., The Sega control box is one single box.
There is no mat included with the Cha Cha's, the Samba Fans and Sega do have one.
Don't have a picture of the controlbox of the Samba Fans, so I wonder how this looks like.
The Sega controlbox has a sticker "Made in Japan", pretty sure the 3rd party stuff is not from Japan, but it's striking how much the Samba Fans and the Sega's look alike...on top the Sega's, bottom the Samba Fans...
