First GBZ wiring diagram

Hello all,

After finding a suitable software program to scrape together a wiring diagram, this is what I came up with. I borrowed heavily from Tinkerboy's wiring guides on his website but I wanted to make sure that I have everything ready to go. One area where I feel shaky on is his new mod for the 5v screen. From that to the powerboost, I cant say I am 100% confident. Please let me know if changes to be made. Labor day looks like to be a busy weekend for a gameboy zero build.

Diagram looks fine. (I did not confirm all the gpios but I'm sure they're all good.

As for the screen. That "5v" mod is not necessary. But it won't do any harm. I also just connect to the original spot on the board.

Not sure why it's grounded to the pi and the powerboost. I always just ground beside the tv signal pin. Either way. It will work as you have it drawn out.

Also. I would power the screen from the pcb test points. As you have it now it is powered from the power module and is apart from the switch meaning it will always be on.
