In the latest version of retropie you can set up a specific button as "enable hotkey" button. So you could set a different button for the controller that you are using. Did this for my Genesis controller too.
Other approach would be to set the enable hotkey in the config files only for this emulator to a different button.

still doesnt work. thats how its looking and the ps3 controller is the only option i can choose whether he keyboard dongle is plugged in or not

I press "F2" on my keyboard.
Works great, i use this to disable Demo sounds and Continues.

more info is needed, please fill out the template from the sticky thread: https://retropie.org.uk/forum/topic/3/read-this-first

@edmaul69 you can just click the stick down that should work good

@mwhitney
Sorry I couldn't reply sooner, I only just woke up.

Glad you got it sorted, if you haven't set everything up it's often easier just to re-flash the sd as you have.
Once you do get everything setup how you want it's a good idea to make a backup img of the SD card, that way if something major goes wrong in the future you just have to re-flash the card and you're up and running again.

Nice! Thank you very much.

Reporting Progress Update...
Got the hard drive working and the skin changes in place. My buttons don't work yet, but the LED does. I just need to get the button scripts installed (POWER and RESET). I will say this.. I think I know what caused the corruption. The PiStation build I'm doing has a microSD card ribbon cable, to make access the the SD card external. When I screwed the top down on my case, I crushed one of the wires in the ribbon between the screws. During all of my re-building today, I kept it simple without using that cable. Everything now works right. I tried hooking up the cable again, and sure enough, I get filesystem read/write errors on my screen. So I've ordered a replacement. Cheap enough, but coming from Taiwan so it might take a couple weeks. The other thing I noticed... since the POWER and RESET buttons aren't working yet, I've had the power going straight into the Pi. I've had ZERO undervoltage warnings flash up on my screen. BUT, once I put the Mausberry circuit into the mix, all of a sudden those lightning bolts started showing up. So I don't know if I have a faulty circuit, of it maybe the circuit isn't capable of supporting the volts/amps. I need to try and get in touch with them and see if they can recommend a solution.

As an aside, but related question.. Does the "Powerblock" people use work in a similar fashion? Detecting a button push then sending a signal to the Pi to shut down, then cutting out the power? If so, maybe it can handle the power?

@moco symlinks are magical things ;)

@rridenour I was wondering if you were able to fix this? There is alot of interest in the DolphinBar Wiimote setup these days and the jitter is annoying at best. I'd love to hear any config file tweaks you made.

I'll give it a shot. Thank you.

Okay. That's got it solved. Thanks again. :)

Oh, nevermind.

A fresh install of UXMLS seems to have solved the problem :-)

@tonythetiger don't use them. /dev/shm/runcommand.log may have more info.

more information about your set-up will help https://retropie.org.uk/forum/topic/3/read-this-first

Did you check the documentation on this site ?

@weed_snorkeler said in Changing the menu key in mame4all:

@riverstorm I don't have a desktop, I only have a laptop. I've been turning off my Pi and editing the config files from the sd card. I'm going to need to get a keyboard some time soon though, I need one.

Ah, that makes sense! I was like this is a first. I do keep an extra keyboard and mouse handy and also the Logitech K400 Plus (wireless w/dongle) which I mainly use for the Pi as it's has an almost full size keyboard, glide/mouse pad off to the right (all-in-one) and the USB dongle is the micro type. It's well suited for doing tweaks in front of the TV. They always seem to be on sale every few months at half price for $20.

Ok, I'll try it. I used mame4all because I heard it had the best performance. Thanks for the tip.

We were having a discussion if mame4all is a valid emulator in this thread (the last 3 or 4 posts). I am a strong advocate for mame4all-pi for the reason you stated and few others. I think the feature and ROM differences are subjective to your needs and I'm not sure if anyone has done any type of actual benchmarking as to which runs games better/smoother framerates. I was a die-hard mame4all-pi user and only converted due to some feature enhancements. I do use lr-mame2003 as my default @dankcushions has made some nice tweaks to improving lr-mame2003 over time.

Another thing I don't care for that wasn't listed in that thread is when you pause in lr-mame2003 the screen goes blank/black which seems simple enough but it's a bit annoying for some reason when you're used to mame4all-pi where the screen is "froze" on pause. It helps to see where you're at before un-pausing. It's easy enough to get around by disabling pause in lr-mame2003 and using Retroarch to pause but I had a dedicated P button on my box that no longer works but the joystick is fine.

For me it's minor issues/polish but not enough to stop me from using lr-mame2003 and I do keep mame4all-pi ROM set handy if needed. I think mame4all-pi is so universally ported it will always have a place. I would try both if even for contrast. I have it on a iPad even and it runs well but there's not much to say for the controls on a touch screen. :)

yeah im looking forward to the n64 classic, cos that will mean new official n64 controllers, i may actually buy 2 cos those things will be worth their weight in gold mint condition in like 5-10yrs.

I updated to 4.2.13 (8094863) this morning and the problem appears to be resolved.

@pjft Awesome, thanks for all the help.

Do you have any idea how long you will be able to power retropie, and the monitor?

If you try to set up the controller mapping, how many controllers are there?
