Sega-Naomi

I have everything working like the sound,the monitor,the game works great with the naomi system.The problem is I can't get the start button,the accel& break unit,the shifter,and steering wheel to work. :smt017 Is there somethig that controles all of these at once?

Yeah the IO. Any chance you have a spare rev1 you could test in place of your actual setup?

Also, make sure you have made all connections like this--->Crazy Taxi WD<---. :smt045

Do the service and test buttons work (not the ones on the naomi unit itself?)



The reason I ask is that not all naomi games check the link to the I/O board, some will boot without reporting I/O board not found.

I've bought another I/O board for my crazy taxi arcade,but still all the controls don't work.The test and service buttons on my arcade don't work,but the ones on my naomi system does.could there be something else that could be causing this?

Faulty usb cable from IO to naomi?

You need to make sure that all connections are made as shown by the wiring diagram. I say this because there is a 5V 'loopback' that needs to be made as well as there may be a need to connect a coin counter. :smt045
