IPAC 2 doesn't work properly

alexjshepler

I've gone through the tutorial on how to properly connect the ipac 2 to the retropie but it didn't work, I've gone through it and done everything by hand, copy and pasted it, and just downloaded the files and uploaded them, but nothing is working. Any idea on how to do it? (I have a 2 person config, 1 joystick, 6 action buttons, 2 buttons for the menu, and 1 for the coin, I have that config for both and I also have an extra one. Lmk what to hook that up to)

If your IPAC configured as keyboard, did you check that the buttons register as keys - either in Windows or Linux ?
What files did you modify for configuration ?
It would be helpful to know something about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Hi, sorry. I'm using a raspberry pi 2 b+, I do have a sufficient psu, and the ipac is setup as a keyboard. I am modifying the files is /opt/retropie/configs/all and some other ones that are in the original tutorial (https://retropie.org.uk/forum/topic/8987/guide-setting-up-a-retropie-controls-using-ipac2-controller-extensive-tutorial-preconfigured-files)

So, what exactly doesn't work - how are you testing ? Did you test the IPAC to see that the keys are registering - to exclude any hardware/connection issues ?

EDIT: what version of RetroPie are you using and how did you install it ?

alexjshepler

I'm testing it by just trying to play games and stuff but the buttons aren't registered properly. And I'm using the most recent version of retropie and I downloaded it from the website and I used balenca etcher to write it to the sd card
Edit: And i did test it on a notepad to make sure that the buttons are properly configured

@alexjshepler said in IPAC 2 doesn't work properly:

Which games ? The instructions you've followed are for settings up RetroArch based emulators (anything that starts with lr-), if you're not using one of those emulators, then the input configuration doesn't apply.

You should start by editing just one file (/opt/retropie/configs/all/retroarch.cfg) and add the mappings for P1 and P2. Can you post the contents of this file on pastebin.com to take a look ?

Here you go

I've also tested it on just the home screen and whenever I update this file it seems like nothing happens

Also my discord is Geekwired#1828 if you wanna talk on there

The config file seems ok - it's the default retroarch.cfg as distributed by RetroPie with your added key bindings. Assuming they map ok to your buttons, they should work in RetroArch.

The RetroArch configuration file doesn't affect EmulationStation. You follow configure the IPAC as any other controller in EmulationStation - as indicated in the docs. This will overwrite the retroarch.cfg file you created, so have a backup before you do that.

I prefer the forum.

@mitu So would I just configure it like any normal controller? and not upload a file? and if so, how would I setup player 2 and coin?

alexjshepler

because it is showing up as 1 keyboard, how would I configure that as two controllers?

mitu

@alexjshepler You can't, it's a single input device (1 keyboard). You just need to configure it to be usable in EmulationStation, so pick one side/player to control EmulationStation and configure it so you can navigate/open/menu/exit/etc.

alexjshepler

Ok, but then how do I configure player 2 for the games?

mitu

@alexjshepler Didn't you already configured your retroarch.cfg for it ? That should be enough. As I said, back up the file before configuring the IPAC in EmulationStation and restore it afterwards.
If your IPAC doesn't work in games, then please specify what games are you launching and what emulator is used.

alexjshepler

Ok, I will try that, how do I configure it tho so that the buttons stay the same throughout the wole system? Like when I assigned A to one button it goes to another when I try to chagne the settings?

mitu

I don't understand, can you give an example ?

alexjshepler

So, when i'm on the home page, I am using a white button for A but in the settings I have to use the red. Its like when I'm on the actual home page (where you select the rom and game) its going off of the butt that was assinged to A (east button) but in the settings its the button that is south

alexjshepler

So for the xbox controller, I set A to A (even thought it reconmends that you set A (retro pie) to the east button (on the controller) but I set A to A and when I'm in the settings (blue background) it uses whatever button is east so on the xbox controller B

mitu

@alexjshepler So what's stopping you from mapping the way you want it ? Just swap A and B when configuring the IPAC.

alexjshepler

I've mapped it so A is A but whenever I go to the settings it uses the right button instead of the button that I mapped it to, and when I go back it maps it to the button that I want

mitu

EmulationStation's settings menu is not opened by 'A/East', it's opened by pressing the button you mapped as 'Start'. Are you referring to the RetroPie-Setup settings ?
