I've not heard of Clay before... or his mulitjamma, do you know where I can learn more about these... does he have a website??

Or .... www.multigame.com

Maybe I should just order from that site... I don't need 4 boards... just two... and even if I order 4 it's only $183.... the person selling here wants $180 and I don't think that includes shipping yet.  ???

teknomedic:

With your setup... have you had any problems with Jamma+ buttons?  I need to setup my CP for games like Killer Instinct and Mortal Kombat.  Thanks for any tips.

Alternatively, search the forums for "MultiJAMMA" ... I have one of Clay's kits and have used it to switch between JAMMA boards and a MAME box.

AND, there is one currently for sale in B/S/T.

Well... I hope you're happy, I'm now out $183 because of that Multi-Jamma, lol... j/k

Look like I'll be trying this Multi-Jamma kit thing then.  I'm still very interested in hearing other (cheaper) ways of doing this in case this doesn't work out the way I hope.  I'll also post back here once everything arrives and update how it all works out and how easy it is to setup.  Lastly, when I hear back from a few of the others that have this up without the use of a Multi-Jamma, I'll pass the info along for those that can't spend the $$$ on one of Clay's kits.

I actually hit this problem with a driving cab...Top Speed.
I needed to have the original game playable, or, with the swap of a few things be able to play more games via MAME.
Glad to say it isn't too hard at all and doesn't use any fancy gadgetry like *PAC interfaces.

The set up now has the lot swappable in about a minute and it's a 3 stage process.
1. Unplug PCB power supply and plug in PC one (will fit a switch in the near future).
2. Connect Ground wires from the original wiring together using a molex (this caused headaches at first, as I didn't want to mess with the original wiring).
3. Plug Jamma header on to Top Speed PCB (it would cause a few glitches if left on the PCB).

The monitor input is split, as Top Speed has a seperate video header and both methods are therefore always connected. No output from the PC gives no feedback signal, nor the other way round with the Top Speed PCB.

For steering I used a mouse hack, the +5V and Ground for the original steering stuff being derived from the PC power supply.
The gearshift has the extra and usually unused 'NC' switch connected for gear shifts in MAME. This works great for loads of games, except Pole Position, which still requires like a double clutching to get it to change gear. The former mouse buttons are used for switching gears, left for Low, right for High.


Another method for running the PC is to directly JAMMA it, something i'm working on and have everything except what you'd think would be a simple 5V to 3.3V conversion circuit. So I still have to use a power supply on the motherboard  ::)
Video out, sound and controls are all easy enough with a PS/2 keyboard hack and, if run from Compact Flash or USB stick instead of hard drive, you can have a none whining solution about the same size as a regular JAMMA PCB :)
