Take a look at https://retropie.org.uk/docs/Keyboard-Controllers/#configuration-example-ipac.

@mlcampbe said in Confused mapping ipac buttons to retroarch for mame:

Is there a standard retroarch <--> mame key mapping that says retroarch "a" = mame "1SW1" and so forth?

1SW1 is an ipac designation, but afaik it effectively means "mame, player 1, button 1". with that in mind, you can see what retropad button = what mame button number via observing what is displayed in the core input remapping menu: https://retropie.org.uk/docs/RetroArch-Configuration/#core-input-remapping (where you can also adjust the mapping).

please fill out https://retropie.org.uk/forum/topic/3/read-this-first for more specific advice - not all mame cores have the input descriptors required for core input remapping.

@mitu that's what i don't understand. Here is what i do:

I add a rom into the fba folder open the rom (the default emulator is lr-fbneo the game opens but i cannot insert coins with any of the buttons even though the "all" retroarch is set to "select" so I edited the retroarch in the fba folder only and nothing, it doesn't work...
Some of those roms work with Mame, so no big deal but i can't get any of them to work with lr-fbneo...

I hooked up a keyboard through the USB and i could insert coins with r-shift key but again the controllers were all over the place...

At least I can play some games now so i'll be trying them with different folders and emulators...

Thanks again

Did you take a look at https://retropie.org.uk/docs/Keyboard-Controllers/#configuration-example-ipac ? It's a page specifically dedicated to keyboard controllers.

@TonyXL When I do this I get a message that says, “error saving controller profile”

@mitu

Thanks, but I've ordered some zero delays. I think that will work for me better.

@mairus Welcome to the forum and thanks for sharing your solution.

Thanks for the continued help...you guys are really awesome!

I mamaged to create an Ssh and used winSCP to visually check the directories but I couldn't find default.cfg file at those locations? Managed to find all my recent Rom cfg files and removed those. Ran a search for the whole sd card for default.cfg and found it relating to lr-mame2003 but with a different pathway(file had unreadable symbols) Removed that and rebooted.
I feel really successful in what I have learned the last few days but my S,Q,W keys are still bound!? I'm using a conventional usb keyboard tonight at home so the issue doesn't seem to be related to my iPac.

My next plan is to change the key definitions in winipac for the iPac board. My player 1&2 pin numbers sw7 & 8's are not used so I will try swapping these keys designations over.
S-L
Q-K
W-C
This will hopefully change the conflicting s q w keys to unassigned pins. L K C don't seem to have any adverse effects in mame. So this might be the solution. On the plus side I've learned heaps the last few days-never thought I'd be able to this stuff

@edmaul69 I'm wondering if I should note, that I disconnected the ipac and used ONLY my keyboard for the inputs and had the same result. Alt on the keyboard worked to navigate back to previous screens in Retropie menus, but did not work in game roms.
