Hey guys! So lots of progress has been made in the past couple weeks now that the new flex cables have arrived. Below are the reversed and slightly revised version of the Ultra HDMI cables for my Ultra VGA board. These were done through OSH Park's new flex service. Though they work, they are a bit more rigid than the original and they also do not have the stiffener for the FFC connector side. It does hold tight though, but I haven't tested it yet to see if the connection is as solid as it feels. They are also about 10mm shorter than the original.
The next was another FPC board for the cart slot. So tired of so many wires. Though this was designed around a specific N64 portable layout, it still will serve well for future projects.
The castellated ends on the board side made soldering to a fresh board extremely easy.
Test of cart slot flex cable. Worked first try and this was a 5 minute relocation.
So even though this looks like a mess now that it's been torn apart a couple times, I'm hoping for some good test results as I have the time to work on it.
