I've a nintendo and sega close console (like this one for example https://s3-ap-southeast-1.amazonaws.com ... f890b3.jpg) and I would like to keep it in this original state, with the original controllers with the 9 pins and the current HDMI output, but changing the inside hardware with a raspberrry PI (probably zero W, or else 3, both are in house already)
First step is connecting the controllers to the Pi and my assumption was to convert the signals inside the console into USB (so I can keep the current style serial connection) and connect that USB to the regular Pi connection (so I can easily also connect 2 controllers via USB, with the Zero W via dongle or directly on the Pi 3).
I do have ordered some test materials, but I think mainly the CP2102 I have now this adapter https://5.imimg.com/data5/LA/VL/MY-1928 ... 00x500.jpg, should do the trick, which I already received.
The question is now; how to connect the serial connection to the CP2102, as I assume I can put in the CP2102 into the usb connection of the PI after that?
There are 5 cables in the connection of the RS232/serial connection (as there are 5 cables in the joystick connected to the main board), but can I just hook them up (I need to google even more for that, but I didn't find the schematics yet of that 5 cables). Or do I miss anything? Or can it be done simpler?
