I have the mikes arcade in my mk1 - for mk1/mk2 switch it works AWESOME.. well worth the money.. just make sure to buy it direct.. I bought mine second hand and the seller gave me a cheap extender.. and the pinouts are wrong on one of the endge connectors and would screw up the video on my second game.. took me a whole weekend to rewire the harness.. but once I did it works flawlessly.. highly recommended.
Lol this is what i need. I have 2 cheap jamma switchers from the early days. One side works perfect, the other side flashing video, i tried out so many possibilities, resolder cables / connectors etc. So now reading your comment i think we have the same switchers. Do you have the pinouts for me ? If you take the bord in front of you with the MAIN JAMMA connector UP then the left side works and right side has the video errors.
Tim.. you have to basically invert the connections.. here is how I did it..
the cheap adapter I had soldered all the +5v and gnd for both sides together.. so that was perfect.. at that point I started there. I plugged 1 end of the adapter to the second board edge.. and then labeled that the component side, and worked right to left, matching the wires from the other end of the adapters pinout - going left to right...
so on a normal jamma adapter it reads pin 1-26 left to right.. and then a - what... x on the bottom side; with the extender - you will have 1 side that is 1-26 left to right, and the other side will be 1-26 right to left, or 26 - 1 left to right.. so the port on one side is pin 26 on the top side, first position, and going down..
Component side edge 1 Top left to right
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
a b c d e f g h i j k l m n o p q r s t u v w x y z
Component side edge 2 Top left to right
26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
Now wire to the matching numbers: 1 to 1, 2 to 2, 3 to 3, etc until its done -- your wires will basically cross over each other.
do this for both sides and it will fix your issue
I just cut the wires right in have.. separated the 2 connectors, twisted, soldered and heat shrunked the connections after I fixed them
