non-libretro emulator for 4.8 rpi4

jamrom2

I assume you mean non-libretro MAME emulaor by the sounds of it.

You can use the base MAME and MAME4ALL as well.

Have you tried to reassign the keys yet? You can do it in any Libretro based emulator by using a USB controller and "hotkey" (should be "select" on a SNES style) and "X" button. This will break you into the settings/config menu of the lr-based emulator you are working with. From there...

Go to Setting --> Input --> Hotkeys --> disable the hot key then scroll down to "Quit Retroach" and set it to whatever button you have "ESC" mapped to on the IPAC.

That should work.

Yes, I mean non-libretro MAME emulator.
I didn't think MAME or MAME4ALL was supported in 4.8? I go to packages and try to install MAME4ALL and it says it's not supported. Is there another way to install MAME4ALL?

The only thing that worries me about disabling the hot key with the SNES controller is that I like to be able to use SELECT-START to exit a game when using the USB controllers (playing NES/SNES).

No, it's not compatible with a Pi4, and advmame 0.94 also.

USB controllers are configured separately from a keyboard-type controller - is the IPAC configured as a keyboard or as a gamepad ? You can still have the Hotkey Enable button set for an USB controller and leave it unset for the IPAC.

@mitu

IPAC is configured as keyboard.

So if I want the Hotkey Enable button set for ONLY the USB controllers and leave it unset for the IPAC is that just editing the retroarch in the "ARCADE" config folder? Or how would I do that?

mitu

How did you configure your IPAC ? Did you edit the a configuration file or used the EmulationStation input mapping menu ?

For what its worth you can see me mucking about several years ago here disabling the hot key and setting the keyboard mapping.

From what I remember the hotkey will still be fine for the controller as it wont read the keyboard binds it'll use its own config.

@mitu
Used the EmulationStation input mapping menu that you get when you first load retropie.

sshht

@Floob
Thanks. I'll check that out.
Do you use USB controllers in addition to your bartop buttons?

I use both usb controllers and bartop buttons + IPAC (which emulates keyboard)

Then it means the configuration settings are saved in the global retroarch.cfg. If you've chosen a hotkey enable button during setup, it was set there. You can override it, disabling the hotkey, per-system (arcade for instance), so that you can use the Esc mapped key to exit, but this also means that any hotkey dependent actions should also be disabled - save/load/reset/menu.

sshht

@mitu

Yes, I really only use the retroarch.cfg in the \config\all directory for everything.

I attempted to disabled the hotkey function and add the exit function to my \config\all\arcade\retroarch.cfg file using the following, but still didn't work:

input_remapping_directory = "/opt/retropie/configs/arcade/"
input_enable_hotkey = "nul"
input_exit_emulator = "escape"

#include "/opt/retropie/configs/all/retroarch.cfg"

mitu

The configuration looks correct. What emulator are you using when testing it ? Do you also have a gamepad connected ?

sshht

@mitu

I'm using lr-mame2003. And yes, i have the usb gamepads connected while I launch the arcade.

I bet if I disconnect the gamepads I could exit the game with 'esc' key on keyboard (or IPAC since that's mapped to esc).

Floob

@sshht
Out of interest, what happens if you hold the hotkey on the controller, and then press exit on the IPAC?

sshht

@Floob

Good idea. Yes, if I hit the hotkey on my USB gamepad and then hit ESC keyboard key / IPAC button that is mapped to ESC, then it exits the arcade game successfully.

I guess I could program a combination of SELECT + ESC on my IPAC instead of just using ESC eh?

Floob

@sshht
It might help if you zip up or pastebin your retroarch.cfgs in case there is something obvious in one of them. I'm assuming you dont have a game specific one.

@sshht
And if you comment out the hotkey enable button line in your controller file, does your IPAC exit with the single esc press?
I think you're right in the easiest way would be for you to use the hotkey on the IPAC unless you wrote a script to change the controller cfg based on the system that you loaded.

sshht

@Floob

Are you saying to comment out the "input_enable_hotkey_btn = "6" found in my \config\all\retroarch-joypads\USB,2-axis 8-button gamepad .cfg ?

Have you tried that ? Disconnecting the gamepads will ensure no hotkey gets set in any input profile.

sshht

@mitu

Yes, when I disconnect the gamepads, then i can use ESC to get the arcade game.

So when I use LR-mame2003 or any LR based emulator with my gamepads connected I can't use the 'esc' key to exit an arcade game.
It's like I need to disable the gamepads and hot key when loading libretro emulators in arcade.
