The charging will work, but not the USB section as it requires circuitry on the PMS2/lite. If you just want usb-c charging I would just get one of those cheap PD boards on amazon.
You can use one pin with a pullup resistor on arduino side. If the cartridge needs to be flipped logic, you attach this connector pin to ground. At boot, the arduino reads this pin instead of the controller combination to change the logic.
Congrats on finishing! The video was really informative great job.
About the High/low data button switching, would you be able to use an extra pin on the cartridges as a select that can automatically configure the arduino rather than remembering to use the button combination?
Hey guys I'm offloading some parts I've been hoarding for a while that probably wont ever see use by me.

Every single solder joint is extremely dirty. you should be using twisted wire with ground for the composite signal or shielded wire even better. The composite signal does not need to be thicker. Thicker wire does not provide any shielding over using thinner.
