would the sega genesis sports pad have the same trackball as in the arcade?

I need a sega trackball....is the one in the sports pad for the genesis the same as in the sega arcade cabs?

Doubt it highly - especially considering the extreme size difference.

cool, thanks! Just looking for a cheap alternative. Plus I can't even find a sega trackball around

[DaveMMR]

Are Sega trackballs any different than Happs?  Because the Happs ones are pretty good.   Check the B/S/T.

I don't know about trackballs too much, but someone told me something in sega track balls is "negative" while happs are "positive".


he said:

all arcade sega trackballs games from the late 80's, 90's and 2000's are the same.

And all use the same optical sense boards for the X/Y and use negitave logic.

These require the special optical/spinner and a Naomi I/O board to function.

Sega trackballs use negative logic, Atari and Happ use postive logic I believe.

Again....I don't really know what that means, but he does and I trust him enough to look for the right one before using the little money I have.
