Can you make the button pcb from scratch??

Ive seen that TinkerBoy sells some, if necessary id buy from there, but id rather make it myself because its cheaper. I was thinking you could do the same as wermy did in his first guide part two for all buttons.

I couldnt find any thread answering this so i made my own. Thanks for the help!

Find a common ground PCB instead and hook all the components up through there. If you do the math you'll find that the prebuilt PCBs that already have power, audio, etc aren't really that much more.

Yeah, you can find GBZ common ground button boards just about anywhere:
My site: http://pocketadventures.com
Ebay: https://www.ebay.com/sch/i.html?_from=R ... b&_sacat=0
Aliexpress: https://www.aliexpress.com/wholesale?ca ... y+zero+pcb
Amazon: https://www.amazon.com/s?k=game+boy+zer ... _sb_noss_2

It all comes down to how much you want to spend, how long you're willing to wait, and which features you want.
If none of those options are acceptable, you can definitely make your own, but if you're only planning to build 1 GBZ it might not be worth it.
