Is there any way to lock down retropie?

[edmaul69]

@capeman copy your es_systems.cfg to /opt/retropie/configs/all/emulationstation/ to keep it from being overwritten. However if you add a system you need to copy that systems info from /etc/emulationstation/es_systems.cfg to the new one. I keep my systems organized by, first, console that i shoved my pi into, that companies other systems by age, (oldest first) then companies by age with the systems of that company by age, then arcade, then pc, then retropie menu.

capeman, i must say your advice was 100% spot on... It is EXACTLY what i needed... not hard at all. obviously id love to have a checkbox to do it, but that wasnt hard.. and everything is reversible. by using winscp :)

thank you again.

@dunginhawk also I was thinking, disable the hot key for the retro arch menu as (hotkey x). Wouldn't want anyone to mess that up. I believe You actually disable it per controller in the controller config files. Meaning you can disable it per controller and if you need access, a keyboard or another controller will work.

[dunginhawk]

I use the hotkey + start button to back out of the emulator... so i need that.
So actually everything is perfect. thank you

@capeman If you change Start and Select button pushes, how do you shutdown?

@ohmycommodore yeah man thats exactly what i mean... it cant be hard to add that, and to unlock it, you type a key combination. UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A B A Start :)

YES THIS! an option to hide and show retropie menu with the Konami code would be literal perfection! Funny thing is this is an exact feature on OpemEmu on mac. Do the combo on your keyboard while the options menu is open and you get advanced options.

I noted this was an issue. I find that using one of the many auto shutdown options or addons such as the powerblock are a good match for this issue.

The easiest is the single button GPIO shutdown option detailed in this video.

There are also lots of demos online of people setting up a "system" on the carousel. Here's one i found on youtube:

@dunginhawk I was actually talking about disabling the retro arch configs menu. Not the hot key itself. Lol

[Capeman]

@dunginhawk Yes, i recommend what @lostless says.

It's very easy to disable specific hot key commands (such as retroarch menu and reset) from the controller while still keeping the hotkey functionality for exiting.

Simply navigate to this folder:
/opt/retropie/configs/all/retroarch-joypads

Open the file that corresponds with the controller you want to remove the hot key functions from

Inside that file you'll see settings that looks like this;

input_device = "USB gamepad           "
input_driver = "udev"
input_r_btn = "5"
input_save_state_btn = "5"
input_start_btn = "9"
input_exit_emulator_btn = "9"
input_l_btn = "4"
input_load_state_btn = "4"
input_up_axis = "-1"
input_a_btn = "1"
input_b_btn = "2"
input_reset_btn = "2"
input_down_axis = "+1"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_x_btn = "0"
input_menu_toggle_btn = "0"
input_select_btn = "8"
input_enable_hotkey_btn = "8"
input_y_btn = "3"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"

Simply # out any functions you want to disable from hotkey activation.

Retroarch menu corresponds to input_menu_toggle. I'd also recommend removing save state functions and RESET for kids, they would get confused if the game suddenly backtracked for or jumped to the title screen for no discernible reason.

And you can switch the exit emulator button to something a little harder to press if you choose, i usually do select + L since that's a weird feeling on the left hand thats less likely to be pressed than start+select. But that's personal preference.

[ohmycommodore]

Can a triple button press be set up? High degree of difficulty and therefore less chance of being selected accidentally. My use case is a system that I use, turn on and let my kids use on occasion, insist on shutting down myself, and when necessary I (and I alone) drop into something advanced like RP config or into menus.

In other words, if it's an interesting discussion... what's the best balance of protection vs not disabling things so completely that it's a hassle?

[lostless]

@capeman actually I would leave reset, it's absolutely needed for one game in the world and one game only. X-men on genesis/mega drive. Can't beat the game without it.
Maybe 2 games. x-men 2 on genesis/mega drive it's used to select the character in the opening level.

@hex @BuZz
chattr -R +i to

• /etc/emulationstation/
• /opt/retropie/configs/
• .... other folders???

Will surly lock files from changing

@capeman this is exactly how @Zigurana 's kids mode works.

As for your hack to lock down the ES menus, how do you exit ES? Do you have an external shutdown switch or something? That sounds like a big roadblock, or am I missing something obvious?

[ohmycommodore]

Hang on, is it possible at all to simply set a password, and protect some of these things that way? Then they don't need oddball multiple button presses, etc. In my head it's still about keeping things open for who they need to be open for... the "admin" essentially. Closed for the rest who wouldn't (and shouldn't) have the password.

[lostless]

@pjft basically the way that @Capeman is recommending locks down the system per controller. If you always use the same controllers, you can lock those down and have a another controller or keyboard ,that isn't locked down and use that to shut Down or restart. Or even adjust retroarch setting. The only thing that you still can't get to is the retropie menu without editing the essystems.cfg from a computer or using a keyboard on the pie and manually edit it from there. That's

I put a posted above with a couple videos to solve this issue. One of them is the GPIO shutdown button and the other is a way to add a shutdown/reset menu as a system to the carousel. These method's do effectively kill the ability to shutdown, as a powerblock user i kind of take that for granted, haha.

I haven't tried @Zigurana's kid's settting, only mostly because I usually stick to the officially updatable version of ES. Is his version merged with favorites/collections? I'm hooked on those now, haha.

[HurricaneFan]

@capeman If you own the necessary hardware, it makes sense to use your approach. :)

[Capeman]

@HurricaneFan
Doing this shutdown method wouldn't require anything extra, set this up before disabling everything else and ES would be pretty kid friendly.

I think we can do better if there is a need for Shutdown system
