I'm going to be modding an Arcade1up machine, Street Fighter in particular. I would like to add a spinner, but not sure how to go about it. I'll be following the ETA Prime modding video on youtube. I know that you run the controls into a usb encoder, one encoder for each player. My question is this....where do I plug in the spinner ? The player 1 encoder, or do I have to use an encoder just for the spinner ?
