Competition Pro with secondary triangle buttons. How does it work?

[jarreboum]

I have now two of those Competition Pro joysticks with two round buttons and two triangular buttons at the base of the stick. I bought the second one on the assumption that my first was broken, but they both behave the same. They were sold as Amiga, Atari ST, Commodore, Spectrum compatible and I'm trying them on a Master System. They have a three way switch on the base with mysterious effect.

 

Does anyone knows how they are supposed to work? Right now the two round buttons are duplicates of [button 1], which I understand is the correct behaviour. But the triangle buttons don't do anything, except when the switch is on the left position, then the right triangle button is also a duplicate of [button 1] (the left triangle button still doesn't do anything). No autofire of any sort.

Ok so I tested it on a 2600 and it behaved quite differently.

- Switch to the left is automatic fire, no button pressing is needed.

- Center and right positions are semi-automatic [button 1] on the left triangle button, while round buttons are still one press = one bullet.Right trangle button doesn't work.

- Right seems slightly faster than Center for the automatic shooting.

 

Any idea why?

These are the latest repro's and are *known* to have been wired incorrectly. I too have a pair, but the regular black and red style - same results as yours. Use as a single button joystick for your Atari and Commodore games or mod it I guess.

Oh ok. Has the correct wiring been posted on the Internet?

 

The box is mighty confusing. So I suppose different versions of the joystick, with the same box, were made with different wiring to accommodate for the different consoles and computers?
