@mitu said in Creating Save States with a Single Button Press:

pressing only Start should exit the game.

My experience with (retropie 4.6) is that (luckily) it doesn't. Which at least for my purposes is good. Should this change at some future version, then if 'input_enable_hotkey =" and single press hotkeys are what's desired, then one would need to change that mapping in RetroArch configurations somewhere to avoid exiting emulator when Start is pressed. (it's almost like the old joke on Windows - you press start to to stop/exit ;-) ).

I set it directly in /opt/retropie/configs/all/retroarch-joypads/THTTHTArcadeconsole2PUSBPlayer.cfg

input_enable_hotkey_btn = "8"

If I use the Retroarch menu (Settings/Input/Input Hotkey Binds/Enable Hotkeys), I can't set it to 11 because is on js1. I can only set button from js0.

@zmanz It doesn't support the hotkeys you might have setup for retroarch emulators, but there is definitely a way to map the EXIT command to two buttons. You need to open up the MAME GUI menu (TAB) and edit the Inputs (General) then scroll down to UI Cancel which is usually mapped to Esc. Hit enter on this item, then press your two buttons at the same time. Wait a moment, and it should register a "1 5" for that function.

What you are doing is called a <CODE AND> boolean key map by pressing both buttons at the same time you are telling MAME you want the function to trigger only when both are pressed. If you don't move to another function, you can map another key, say for example that you want to also keep ESC mapped, you can add that one right after. If you move away to another mapping function and come back, it will be replaced.

You can do some pretty nifty stuff with <CODE AND> mapping as well as <CODE NOT> mapping (in which you double-tap a button to exclude it). With AND and OR and NOT combinations, it is possible to make a single joystick move a tank that would normally require two tank sticks.

I'm experiencing players constantly quitting games by mistake.

Which players ? Please open an new topic and explain your problem, don't bump 2 years old topics.

@potatobox

ok... you have to try... the command above to see in detail the two controller.
sudo jstest /dev/input/js1
sudo jstest /dev/input/js2

this is the method to test joypad
some people have problem with two joypad... "some cases"..

i loose many ours to understand the behavior of a self-made joystick to bar cabinet ... and I still have some minor problems
retopie 4.1 is a great project.. but there is some little matter to fix..

try to understand if it responds in correct mode... than try to connect "only" ps4... and test it alone.

@mediamogul Ah! Thanks everyone for that info. I was also hoping to increase the buttons you have to press to RESET the game (instead of hotkey+b), but I guess that's not possible yet.

Did you ever get this figured out? I'm trying to use buttons hooked up the GPIO for save/load/exit and I have not had good luck. I did try to use the Adafruit RetroGame, but I couldn't get it to work.

Hi!

Yes that's what i mean => Hotkey used in emulator (emulationstation is OK and as you say, don't have/use hotkey)
I read the wiki about the file retroarch.cfg (and already edited this one) but in lr-FBANext, i still have a hotkey active (the one that make the game on "pause") and i wonder if some emulator core configuration file have also some hotkey.
If yes, where are they?

Okay, installed everything from a fresh RetroPie 4.1 image and also clean install of AM from source. I'm on version 2.2.0 of AM and everything is working as expected. The ghosted keys are no longer an issue, and as a result I don't need to futz with different key settings for exiting a game in retroarch. I'd like to figure out why that was an issue for me, but for now what I have is working. In windows I programmed the "exit" buttons for my minipacs with the WinIPac program to be macros of "start+select" and it works perfectly.

As a side note, it seems the issue was with sfml-pi. This explains why my 2.2.0 AM was still giving me issues. I had not gone back all the way in the steps to the sfml-pi portion.

Thanks all.

@protoman

I just edited /opt/retropie/configs/all/retroarch-joypads/Xbox360WirelessReceiver(XBOX).cfg and changed:

input_enable_hotkey_btn = 10 #Guide

If that doesn't work then make sure to put " (quotes) around the number 10 or if you already have the quotes then remove them.

I see. So Retropie and Retroarch are two different things... Ok ! Thanks for the clarification

@BuZz Thank you. I just realized I could configure this within the input configuration of mame4all. I was working too late last night I think.

@Afgin

Never mind.

Problem has miraculously disappeared. Don't know what I have done differently, but seems to work now :D

Hi!

What type of iBuffalo controller are you trying to setup? The famicom version (red and gold) or the snes version?

I started a new topic on this and I hope to get some replies to help me out... Are you still having this issue? If not how did you get it to work?

Thank you and have a nice day!

@bkibalo this post has useful MAME info:
https://retropie.org.uk/forum/topic/2859/how-to-use-mame-with-retropie-help-guide

ok that helps thanks.. I lost my ability to use the MAME tab menu now... sigh..

Strangely, I have updated to 4.0.2 without any issues. All hot keys with Select button worked like a charm as before. How luckily I am!
