Is the Namco 246 (Tekken 4 in my case) the same as Jamma, or is it like the system 32 where you would need a kick harness to play a standard jamma board? I was wondering cause I recently purchased a Double Dragon Board (my 3rd one) and would like to hook it up in a machine to play.
Thanks,
Kane


*Edit*
Nevermind, after careful observation I figured out it had a kick harness. Guess I'll have to jump the wires no biggie.

The i/o hooks up to a standard JAMMA harness. Tekken 4 uses an auxilary kick harness but hooking DD up to the JAMMA edge should work fine.
 
it worked but I turned it off because I saw that there is no wire running to the -5v? Does this matter? I'm guess it would but yea nothing in the namco harness for -5v.
 
Not all games use -5. If it doesn't use it it doesn't matter. I think some used it for sound maybe?

correct. HOWEVER, there is an exception, I think Neo-Geo boards can get fried if you run -5V to them. one of the reasons those JAMMA 6-in-1's don't have the -5 hooked up...

some games used it for sound (practically every modern Williams/Midway game), I think others used it for additional voltages... like I think Defender utilized +5, +12, AND -5 for the RAMs or something like that.

for all intents and purposes here though, I don't think it'll make a difference. :)
