Spend a lot of time this weekend building all the different cable adapter.

I think they take me around 20 min / 30 min to build each. Really happy with how the PCBs turnout. The gates size is small but still easy to manage. I think building the original Saturn cable prototype took me around an hour and 3 hours to troubleshoot. Those boards are a real time saver and they look really nice.

Prototype BlueRetro + Saturn cable Vs. BlueRetro DevKit + New Saturn cable

NES, SNES & Saturn

I re-validated FC/NES, SNES & Saturn cables in all modes supported and everything works as with the prototype cables.

JVS

I found an issue in the JVS 5V step up circuit. I connected the feedback pin to GND rather than the power output! I will correct the Kicad files but will not reorder new boards. I'll just fix the boards I got by cutting the trace.

Cables for upcoming new system support

I was originally planning to built cables only for my short term need for MegaDrive/Genesis, PSX/PS2, & NeoGeo software development up until v1.0. But while I was at it I decided to do a few extra ones including PC Engine, CD-i, 3DO, PC-FX & (S)NES classic systems (Wii ext.).

Doing so allowed me to validate that the detection code works for all of those systems flawlessly. It was also a good test to validate that each system can power up BlueRetro. I actually found out that PSX & PSOne system does not provide enough power over the 3.3v output to power BlueRetro! PS2 got no issue, however. Since I'm using a low voltage drop regulator (for N64 3.3v only) the voltage input range max out at 6V. PSX/PSOne second power output is ~8V.

To fix this problem I will redesign the passthrough cable PCB to include an LDO on the bottom side to convert 8V to 5V. This will be only populated on the PSX/PS2 cables.
