Hello all, Not sure if this is the right section to make this post in.
Disclamer: I am a beginner with RPi and RetroPie
I’m in the process of building my first MAME arcade inside a briefcase and am looking for joysticks, buttons and a controller to connect buttons/joystick to RPi. One of my main priorities is to keep cost reasonably low.
QUESTION #1: I was doing a bit of research and came across an arcade kit assembly and the guy just plugged the buttons and joystick straight into the RPi’s GPIO (see link, 25:36 – 32:51.) https://youtu.be/ViLRv6JK45I?t=25m36s
How is this possible? I’m not using this guy’s kit, can I do this on my own?
QUESTION #2: How many buttons do I need total? Also how do I lay them out?
QUESTION #3: Are these buttons (linked below) any good?

QUESTION #4: Is this joystick (linked below) any good?

Answer 1: he supplies his own software to read the GPIO inputs from the joysticks/buttons. You can try and incorporate his software into your project (I think he provides it for free), write your own, or find another software option. Personally, I got the ControlBlock add-on board from PetRockBlock and intend to use that for my arcade joysticks/buttons.
Answer 2: lots of different options here. I believe MAME uses 6 buttons, two rows of three, plus a coin button and a start button. NeoGeo used one row of 4 buttons. Console emulators use from 2 up to 8 buttons depending on the system emulated, plus a select and start button. I’m still trying to figure out my exact layout. I think I’m going to go with two rows of 4 buttons (allowing up to 8 buttons for PSX), plus a start and select button, and possibly a few more, not entirely sure.
Answer 3/4: I used this article to learn about the options for sale:maughanoramaParticipant03/13/2016 at 18:38Post count: 11
im gunna get one of these, it gives 26 usable on the pi + 32 inputs on the card :)

Hi cheif, I am having problems with the controlblock so I am probably going to take this route, can you tell me if you got this working and how you did it? Many thankschiefspikeParticipant03/16/2016 at 18:40Post count: 2
Hello Mr. sheepishbacon,
I would’ve used GPIO to connect my controls but my RPi 3 is still incompatible. I have linked below to the software, it’s called ‘Porta pi’ but it’s really just retropie with GPIO support.
As for me I’ll be using the guts of a keyboard to attach the controls though I’ll probably switch to GPIO when RPi 3 is supported.petrockblogKeymaster04/02/2016 at 21:27Post count: 1828

Can you tell me what kind of problems you are facing with the ControlBlock?
