Hi everyone, I'm thinking about getting a Tekken 4 cab so I can convert it to a Guilty Gear X. I got a capcom IO so I think I'm ok on sound and controls, but I'm not for sure if the power is compatible. I saw that there was some kind of splitter before the power connected to the board for the System 246 and I know the connections coming from that won't work, but I think what that splitter connects from might. Thanks to anyone who can help.

Hard to say exactly without knowing for sure what power supply is in the Tekken 4 cabinet.

I would say it probably has a regular jamma power supply and the system 246 board is being powered by the namco jamma adapter. If you use the capcom i/o you might have problems powering the naomi and gd-rom if Guilty Gear is a gd-rom game.
 
Do you think enough will get though without the GD rom? I was checking around, the splitter thing i was talking about is what I attached. But I can't get a view of the pins to see if it would be compatible.

Capcom I/O works with Naomi 1 and carts

It does not supply enough power to run the Naomi 2... or the Naomi 1 with a Net DIMM board or the GD-ROM. You need a power supply capable of putting out 5.0, 3.3, and 12v to run the options.

Got it. So I guess my main question is, is the splitter I mentioned before standard in Tekken 4 cabinets, or does the connection go straight to the system? My thinking is that the splitter takes whatever the naomi universal uses for power and converts that to the system 246. So, theoretically, connecting it without the splitter should work fine for naomi since that power set up was meant for it anyway. But since I there's not a lot of system 246 docs, I don't know if that kind of power set up is common/standard.

Thanks for the help with the minimum power requirements.
