I have a namco system 256 dedicated tekken 5 cab and was wondering how much of a PITA it would be to make this a 2in1 with tekken tag tournament.

My main concern is power and the button layouts. I’d have to drill 2 more holes for the tag buttons which is no problem, but their notations are different

In Tekken tag button 3 is the tag button, but in Tekken 5 3 is left kick. I’m not sure how I’d be able to have button 3 be kick for 5, and tag button for ttt when switching. Does anyone know a workaround? This is my first machine so please explain like I’m five.

The power is my other concern. Do I need two power supplies or something? Would there be any risk of frying the boards? Perhaps I’m overthinking it but it’d be nice if there was a switcher that recognizes this

As far as I know, tekken 5 is running on jamma and not jvs. I’m inclined to believe this because in the service menu “jvs” isn’t selectable and grayed out.

Any help would be appreciated
 
As far as I know.. If you use a RiddleTV switcher like the 2-in-1 switcher with the fighting board expansion your buttons shouldn't have to be rewired. I'm in the same boat project wise. I'm trying to hook up tekken 1 - tekken 5 in one cabinet using the 6-in-1 switcher. I don't have to rewire any buttons when everything is hooked up. Hopefully that helped? Sorry I've been playing Black Ops 6 all day and my brain is fried lol.
 
If you use a RiddledTV switcher and the Namco Jamma IO, power and controls should be handled OK. System 256 uses more power than System 12, but I think you could find a decent middle ground between them.

I think the bigger issue is does your monitor support 15khz? I thought dedicated Tekken 5 cabs came with Sanwa 29e31s?

I just finished a restoration of a dedicated tekken 5 cab

What is the model of your office?

Thank you for your response. Can you elaborate on finding a middle ground in terms of power?

Regarding the monitor, I honestly don’t know. Like I said this is my first cabinet so I’m a little out of my depth when it comes to the tinkering side of things. What would be the best way to find out what the monitor is and its compatibility with 15 kHz? I assume that’s what tekken tag needs?

No problem, thank you for responding! I’ll look into those switchers more. In your project have you had any monitor issues at all? Another commenter mentioned compatibility and I’m ignorant on this end too
 
The control panel is already pre drilled for 6 buttons btw.

identifying the screen: you need to remove the backpanel covering the screen. You'll then be able to see the chassis of your monitor and/or stickers on the tube itself. Take pictures.

if it's indeed a 31hz only, you could get one of these cheap gbs8200 converter to convert 15 to 31. not the best but it works.

None at all. If you have the Namco 256 system running through the i/o then you should be fine!

Yes I saw they have spots there when I opened the control panel. So those are drilled already and not just outlines? Do I just apply pressure and pop the holes out or something?

I’ll figure the monitor out when my tools come in and send pictures but can you confirm the relevance between monitors and boards? I didn’t think this would be an issue of all things and am ignorant to why it matters
 
Tekken Tag outputs 15khz. Question is does the monitor support it.

If it doesn't, then you'll need some way to upscale 15khz into 31khz.

You'll also need a separate switcher for video.
 
RiddledTV are great but if it's just 1 button you could remap it with a dpdt switch and you can do multiple with a piano switch. Happy to elaborate if needed.

...well I don't know cause I have more than a dozen other cabs for 6 buttons! :D ... so I kept tekken 5 original because it's really cool, yes still today.

If I remember it's just the metal top layer that's not drilled. So you would need to drill that part, carefully!

I'll let others speak to the monitor related stuff but I can comment on these two items, since I own both games and switch often enough between them in a shared cabinet.

Controls: if you plan to swap between these games regularly, I would highly recommend to get a JNX kick harness adapter for Namco System 12 (TTT board) + CPS1/2 (whatever your preference) and wire up kicks to that harness. All of my JAMMA machines are wired to CPS2 standard so that option is what I go with.

JNX adapter for System 12 looks like this:

On the System 256 end, you say you're running on JAMMA which if that is true then you should have the Namco I/O board to route JVS controls to JAMMA. From there, there should be a harness connection which handles kicks for Tekken 5. You can manage this any number of ways but what I'm doing on my end is using a CPS1 to CPS2 style adapter, plugging the CPS1 end into the Namco I/O. I don't recall if I had to re-pin or not to match up with the I/O board but regardless, the whole point for me was a quick swap of the CPS2 kick harness connector when changing games, not needing to rewire the buttons directly.

Here one of mine for reference, although not pictured is the I/O in this case. There are lots of these style of adapters available from various sources.

Power: I run each of these games primarily on JAMMA cabs. TTT is easy, just gets power from the harness directly. Tekken 5 (DR in my case) is not as straightforward. In one cab, the power supply wired through the I/O is enough to run the hardware + JAMMA conversion. In another cab, not so much and as a workaround I power the System 256 on a separate power supply while the JAMMA cab runs on its own for everything else. I'm not sure how committed you are to the JAMMA switcher idea, nor am I familiar with the Tekken 5 cab internals as I don't have any of those. For the sake of simplicity and ease of use, maybe a better play is to manually swap JAMMA connections & kick button setup whenever you plan to change games inside this cabinet.
 
If the plan is to use a switcher and only have Tekken games, then using a CPS2 style kick harness doesn't really serve a purpose.

Since it's just two buttons per player, you could have these routed through the jamma connector.

That may or may not help in this case, depending on hardware details and the lengths OP wants to go to. Here is the situation...

TTT had Tag button wired to input 3, which already exists on the JAMMA connector. Left kick (in Tekken terminology this is "3") & Right kick (Tekken = "4") are only accessible via auxiliary connector on System 12, so this has to be accounted for regardless hence the kick harness adapter suggestion.

I don't recall how System 256 handles "3" & "4" by exact pinout via JAMMA conversion with Namco I/O but for sure this has to be accessed through the auxiliary connector on that board. The same is true for some other 2x6 games, including stuff like Capcom Fighting Jam - not enough inputs on the standard JAMMA connector to support the game. I took a pic this morning on what my setup looks like to supplement my prior post:

OP has a choice to make either way on how they want to manage these buttons, as far as working with each auxiliary connection vs hacking each JAMMA connection to include 4 extra inputs. Tekken is not a lot different from a bunch of Capcom and Midway type fighting games in this respect and when you account for changing games in a shared machine across different hardware platforms it becomes more tricky, which is the case here also even in the same game series.

IMO I think the more important question is how to handle power for both boards. Also why I don't easily see a path towards a seamless JAMMA switching solution while both are powered at the same time but I'd love to hear from someone else who has done this successfully.
 
Tag is button 3 as it should be. It's the top right button.

123
45

For the Tekken Tag board you put small jumper wires from the auxiliary edge connector to the jamma edge. If you're lucky, your board might already be modded, because this was super common with operators back in the day.

Same logic applies to the Namco Jamma IO.

As for power, it's not an issue with the RiddledTV switchers.

If thegamewiz64 has a trisync monitor, it's smooth sailing all the way.
