Champion Edition CPS2 Key Writing Cable

Need Key Writing Adapter Cable for your "Champion Edition" Darksoft CPS2?

This is a 4 wire adapter that connects to the 6 pin headers on the kit and CN9 of you "B" board. This is approximately 4" long for easy connectivity...

All units of the Champion Edition version, come with a firmware installed that allows to use original untouched romsets. In order to use them, you need to plug a cable between the main PCB of the kit and connector CN9 of your B Board. If you have one of the old type B boards, then, you'll need to solder 4 wires between this connector in the main PCB of the kit and CN2 of your B Board. Further details are given below.

Programming of the key is done with 4 additional signals called DATA, CLOCK, SETUP1 and SETUP2. Those signals are available in pins 2,3,4 and 5 in the connector J18 of the multi.It's located besides the microSD slot. There is a special connector, in the main PCB of the multi, so that it's very simple to connect to the same connector that you will find on your B Board. This applies to the revisions 93646B-5 and upwards. The revisions 93646B-3 and 93646B-4, don't have this connector. However you can find the very same pins available on the connector CN2.
