As @mitu said. The reason behind it is that the mappings are stored under the name of the controller in the directory /opt/retropie/configs/all/retroarch/autoconfig/. Thus, if you have identical controllers, only one mapping will be stored for both of them, and if their wiring is different, their common mapping won't fit one of them.

edit: "will be" -> "are" + "doesn't" -> "won't" 😉

So I figured it out I believe. You were right on with my joystick. It was mounted opposite of the other one. I also realized that the reason the start button just stopped working is because the master controller which as you say there is only one for now. Is the other controller so it works in menu but not in game. Which makes sense now knowing the retroarch and all hotkeys only apply to the master. Thanks for the insight

@mitu @clyde okay thanks

@riverstorm It's the wrong way round in every emulator. I just learned to live with it so far, and play nintendo style, instead of sega style ;-)

@ooskay Instead of bumping year(s) old topics, why don't you open a new topic, explaining what's your setup and what exactly do you want to do.

@Tigry Thanks for sharing your solution, glad you found it.

Just for completeness, I was going to suggest that you could use @meleu's joystick-selection tool to see if your sticks are configured as player 1 +2. If not, that could've been the reason why they didn't work in RetroArch.

@lurker Thnx. I checked out the USB encoder product and seems like this is the correct product for easily adding autofire. Maybe it would be possible to do it with the controlblock as well but requires more skills than I have. I like the power switch feature and ability to connect two cotrollers to the controlblock but the dufficulty of adding cooling solutions with how it stacks on top of the pi is annoying.

@johnny5126 said in How to know what button is what:

where i can figure out what button is assigned to X, Y, etc? I have my buttons connected to an Ipac2

You know what you wired up to the ipac2 terminals so therefore you know what function each button has according to the instructions for the ipac.

nods to the trackball joystick doesn't cut it

I would like to use combo inputs but I am not sure how since doing it in the emulation station menu only allows single buttons

@fredbuilder This was discussed earlier in this thread, but via direct editing of the config file. Thanks for the addition about the GUI and for the video. Nice handheld. 🤩

Thanks! Deleting the .cfg files did it. I was dumb and left out the fact that, though it was a clean install of retropie, I coped my roms dir over from another machine. I either forgot or never new that mame2003 stored those cfg files below the roms dir.

@bassman6805 eBay and amazon have them in abundance as do RS/Farrell and Mallon. Just search square black non locking push switch. Be careful not to buy on/off latching switches which look identical but are longer.

@40wattrange

Unfortunately, you can only remove it globally. It would work for what you want, but the rest of the hotkey combos would be affected. For example, pressing 'start' by itself would always exit a game.

@jason said in Hotkey Questions:

Looking at the default hotkey list, I see input_state_slot_increase_axis & input_state_slot_decrease_axis

This is to switch the save slot number upwards/downards. You can have more than one saves state slot, using these controls will switch between them (0, 1, 2, 3, etc.).

@caver01 I second this. On the BYOAC forums there's lot of advice to find regarding the build itself, but note that not everyone thinks very highly of Raspberry Pi's there, so questions regarding this is better asked in this excellent site :)

@dankcushions thanks. I didn't think about the R/L buttons on those SNES controllers.

@michael40475 You could do the same way most people do here: burn a clean Retropie image into another SD Card, put into your RPi, put your games on it and enjoy.
