gpio controllers (2 players)
-
Hi, I use mk_arcade_joystick_rpi to achieve something similar in my Bartop Arcade Cabinet. I have the full Super Nintendo set of buttons for each player (see image at bottom of post).
If you want to go down this route, use the wiring diagram on their website (for the RPi2, it still works): https://github.com/recalbox/mk_arcade_joystick_rpi but do not follow their install instructions for the software. I will check as it used to be in the optional components on RetroPie.
[EDIT] It is in the drivers section, called mkarcadejoystick
The button order that seems to work best for this configuration is:
Top Row: LB X RB
Bottom Row: Y B A -
Wow!! This is the best forum ever, no kidding! I have never seen such activity and willingness to help others! Thanks so much!!
@caver01 Thanks so much! I will shoot him a message! Also, I was thinking on the IPAC, but I wanted to go the GPIO way as I live in Brazil and I would have to import it as I have not found it anywhere, it would be expensive and take a very long time to arrive.
@simonster WOW! Thats amazing!! Thanks so much! I think thats exactly what I need!!

@brurpo No problems, let me know if you need any assistance, I have had it working for about 18 months now (originally on a Pi2 and now on a Pi3)
-
@simonster is the gpio layout the same?
-
This is the pinout you need, pin 1 is nearest the display connector (hold the Pi with the USB ports pointing downwards to match the image)
-
@simonster thanks! you are an amazing person! I was not sure if the pi2 and pi3 had the same layot

@simonster Nice bartop! WoW. Tell my on thing... I din't try yet, but I'm using Retropie 4.0, this gpio instructions and driver config for recalbox will work in it?
-
If you are using RetroPie, you can install it from the RetroPie Setup menu. It will work fine.
If you are using recalbox, the pinout above is the default for recalbox. However I don't know about configuring it as I don't use it.

@simonster Hello, I'm using retropie 4.0, do you know what are all steps to configure the retropie to recognise gpio pins directly to the buttons and directional switchs? I just installed the snesdev drive in the retropie config and enable it in the autorun emulationstation, but when i try press any button nothing happens.

@helitoncosta , You have the wrong driver. You need mk_arcade_joystick from the drivers menu in RetroPie setup. Once you have done that, if you have connected to gpio pins as per the diagram, attaching the ground of each switch to a ground on the Pi, it will detect 2 joysticks with 8 buttons each. You can then configure these in Emulation Station.

@simonster I am on retropie 4.4.1 trying to get my 2nd player to work and it detects it but doesnt detect me pressing the buttons and help? Thanks!

What do you mean, it detects it?
Can you give some information about your setup, are you using mk_arcade_joystick? How have you configured it? What hardware are you using?
