Gamestart without i/o board?

[OldFoo]

hi there..



Greetings from Germany..



i have bought a naomi board with virtua striker 2 ver.2000. It was delivered with a 110v power supply.

I have make a atx power supply adapter and works now with a 220v pc atx psu.



This board hasn't an i/o board. The game won't start.. No jamma i/o board found..



Here is my question.. Could i skip the i/o board check to start the game? I will see whether the game works..



Have anyone an idea?

Generally speaking, no. Sega Naomi is meant to be in an arcade environment so it expects there to be an I/O board.
