The Circuit on the Puzz Loop 2 adatper is different than the one on the Brizzo Adapter.
Brizzo's adapter is based on a diagram from SNK for use with the MVS I believe.
The brizzo Adapter uses a flip-flop and a pulse generator along with some AND gates (for direction control)
The Capcom adapter uses multiple flip flops and a counter.
They're a similar concept but I'd venture a guess that they have different output pulse frequencies. the major difference is that the Brizzo/SNK adapter is intended to work with games that are expecting a joystick input, the Capcom adapter is only designed to work with games that are explicitly expecting a spinner and the adapter.
