emulationstation should (if the drivers are included) work out of the box (use the gui controller config option)

and for configuring controllers for (most) of the emulators use this guide (from point 8 forward, point 10 describes how to add a hotkey to enable quiting the emulator/saving/loading)

Updated for 2.3: Step-by-Step Guide

some systems like gba and n64 (at least i know about those 2) will need a special configuration but most will work just fine with this guide

You can also assign a hotkey on a diffrent controller your not using. (I got 2 snes and 2 n64 controllers hooked up. i have all my Hotkeys on the snes controller while only using the n64 controllers inside mupen64plus)

The Video herbfargus posted explains it pretty good where to set the Hotkeys.

I have my MiniPac working with both mame and nes, now. I went through the retroarch.cfg line by line. I removed a bunch of extra stuff after I read online that joystick/gamepad configuration may take precedence over keyboard and mess stuff up. That shader hotkey is in there, make sure you remove it if you have buttons bound to it.

Also, you can’t use raw numbers like that. The comments in the cfg file right above output will tell you all the possible options. I think what you want is:

input_player1_start = num1
input_player1_select = num5
input_player2_start = num2
input_player2_select = num6

If all else fails and things still aren’t working right, quit out of EmulationStation and run: startx from the command line to get into XWindows. From there, you can run: xev from the terminal and it output the keypresses that your joysticks and buttons output.

Hope that helps!

Without the changes to the hotkey, the coins in ’88 Games didn’t work in FBA and Mame. So I suggest it is an issue with retroarch and not the FBA core!

[quote=89770]Has anyone found a way to enable a hotkey for exiting the the emulator?

Anyone? The testing one in setup is a lot better on rpi2

I can’t use my hotkeys to get back to the menu. It works for any other emu. Any ideas?

Has anyone found a way to enable a hotkey for exiting the the emulator?

Maybe you should try and set the hotkey (select) to another button. You will stumble across another problem when you use select as the hotkey. In some games you can’t insert coins with these setting.

I change the hotkey to the left trigger and no more problem with inserting coins. Maybe this will fix your exit problem too.

Hold down “select” on the joypad, then try F1, or n, m etc…

Its because you have set an enable hotkey function.
input_enable_hotkey_btn = “0”

Details are here:

It isnt necessarily a hotkey combination as those aren’t currently supported. You basically have to choose a key you don’t use as the key exit. See this video:

This is a easier solution but changes the hotkey to all emulators (in case you use multiple systems like me).
My solution just apply the change to fbalibretro and you can still exit by pressing Select+Control (has this is configured in retroarch.cfg file).
You have now two possible solutions for your problem which is good because you can choose the one that fits you best.

Considering polluxpt solution I found a somewhat easier solution for autodetect controllers like the PS3 one.

Just go to …

/opt/retropie/emulators/retroarch/configs/

Find the config file for your controller and change the line

input_enable_hotkey_btn = “0”

to another button.

Here “0” stand for the Select button on the PS3 Controller. I changed it to “8” which is the left trigger. No more coin problem!

To exit an emulator you must now press left trigger and start!

This should answer your hotkey questions – its really pretty clear once you get the hang of mapping what you want.
Check the other videos there for controller configs (I have a playlist there for that).

A few tips from my own experience:
– /all/retroarch.cfg is the default control scheme (and settings) for all retroarch emulators
– /genesis/retroarch.cfg is the control scheme and settings file for JUST the genesis emulator, and any settings within it override settings in the /all/ file.
– If you’re using an old “Skeleton” retroarch.cfg file, note that a lot of the button names have changed.

I spent ages trying to get this to work, which I had copied from an old thread:

input_enable_hotkey = "6"
input_menu_toggle = "3"

The correct code is actually:

input_enable_hotkey<strong>_btn</strong> = "6"
input_menu_toggle<strong>_btn </strong>= "3"

That one drove me crazy X-D

@warmania,

I use these lines on the very end of my retroarch.cfg for using Select”+”Start” to leave the emulators.

input_enable_hotkey_btn = "8"
input_exit_emulator_btn = "9"

The number of the buttons may be different for your “select” and “start”, if you know what they are, just use the proper button #s.

UPDATE: The solution for the Mayflash stick is embarassingly simple. I checked the Mayflash website and found out that if you press Auto and Clear together once the stick becomes a normal two-axis stick, press them again and it goes back to a hat switch. For MAME doing this is enough, the default controls will then work happily.

Sadly the stick doesn’t remember this and defaults to hat switch mode so you’ll need to do it every time.

P.S. If you do that and return to EmulationStation you won’t be able to navigate until you re-configure the stick using the GUI. Just toggle back to hat switch mode, bring up the menu, click Configure Input, toggle back to axis mode and go through the process.

I also modified my config file so that the stick works in RetroArch in axis mode:

input_device = "MY-POWER CO.,LTD. Mayflash Arcade Stick"
input_driver = "udev"

input_a_btn = 0
input_b_btn = 1
input_x_btn = 4
input_y_btn = 5
input_l_btn = 2
input_r_btn = 3
input_l2_btn = 6
input_r2_btn = 7

input_select_btn = 8
input_start_btn = 9

#input_up_btn = h0up
#input_down_btn = h0down
#input_left_btn = h0left
#input_right_btn = h0right

input_l_x_plus_axis = +0
input_l_x_minus_axis = -0
input_l_y_plus_axis = +1
input_l_y_minus_axis = -1

input_enable_hotkey_btn = 8 
input_exit_emulator_btn = 4
input_save_state_btn = 2
input_load_state_btn = 3
input_state_slot_increase_btn = 6
input_state_slot_decrease_btn = 7
input_menu_toggle_btn = 0

Yea buddy, I tried it without player 2, also tried it just with the “player1” lines of code active, for some odd reason as soon as the prefix “player” is included in the lines of code, retroarch seems to refuse to acknowledge their input completely, I know the controller file is being passed to retroarch correctly as the hotkeys to exit the emulator remain working but not the controllers, in a bit of a pickle Haha !

Having a similar issue myself still mate, cannot regardless of which combination I try get player 2 (or 1) to work in retroarch emulators. For some reason when I add in the prefix”player1″ or”player2″ retroarch then seems to ignore all input from these buttons and Joysticks, the only buttons that remain working are the hotkey enabled buttons. If i remove the player prefix from each line of code, for instance

input_b_btn = “12” (Works perfectly)
input_player1_b_btn = “12” (Stops working)
I’ve pasted my config file for the Xin-Mo in retroarch incase anyone spots a glaring error that I’ve missed.

Cheers
