I see a lot of people asking about how to create a button PCB using copper tape, but not a lot of guides on how to do so. I wouldn't call this a guide, so much as what I did that worked for me.

First, I picked up some 1.5" x 1.25" protoboard from a local shop. I got ones where none of the pads are connected by default:
Next, I laid the conductive pad on it and traced around it.
Then cut the board along your traces. Make sure to leave a little room on all sides for gluing it on later. Put your conductive pad back on the side WITHOUT the pads, and flip the whole thing over. Using a sharpie, mark a spot in between 4 pads like so:

0 - copper pad
* - Sharpie mark

0 0 0 0 0 0 0 0
0 0 0 0 *0 0 0 0
0 0 0 0 *0 0 0 0
0* 0 0 0 0 0 0* 0
0* 0 0 0 0 0 0* 0
0 0 0 0 0 0 0 0
0 0 0 0 *0 0 0 0
0 0 0 0 *0 0 0 0



Now we can add the copper tape. You can use whatever pattern works for you, but I like the one I've come up with. It uses a common ground wire for all the buttons reducing my wire count. You're going to want to make sure there is a small gap between your pieces of tape so as not to bridge any connections.
Once you're done, it's time to solder! Strip your wires and put them up through a hole not covered by tape, but close to the piece to solder onto.
Good luck and happy building!!

This is so nice! Simple and straight forward!

Could you take a photo of the inside of the raspberry pi so I can see where to attach the screen and raspberry pi to the mintypi.

Could you also post a picture of the bottom of the proto board when it is all finished.

It's an open board. There is no inside.

As for your question, you need to research.

How do you connect it to a raspberry pi

Solder the wires direct to the pi's gpios and use adafruits retrogame script to map them.

Could someone make a schematic of where the wires should go through?
