@mitu Will do. Thanks.

@backstander I tried that didnt work as well. I have a feeling my SD card just isnt upto scratch.

I got myself a Pi 4b now with a 64GB micro sd card, the "dtparam=sd_overclock=100" and it works fine. Consider this case closed, cheers for all the input though guys :)

@mitu I have tried disabling it, it still doesn't work. I honestly don't know what the resolution is for my screen, I think it's 720x480. I'm actually using a car dvd player, the kind that straps onto the back of a headrest. I'm using the composite output.
EDIT: Ok then, I just rebooted without touching anything and it's working fine, so thank you for your help.

You may be able to get it cheaper from a local vendor.

@mitu i have another respberry pi2 , I will check it and update

@mitu I did it, but then suddenly my wi-fi dongle stopped working. Then I tried some more troubleshooting attempts for that and messed stuff up even more.

Much as it pains me, I'm just reinstalling RetroPie and doing it all from scratch. I made backups of everything, so hopefully I'll be able to salvage some of my customizations.

@culebra said in USB ports not working on raspberry pi 2 B:

DC 5V A2.

2A is not enough

@SonPluck No problem. But it says to hold any button to skip.

I think I found my issue. Apparently it make a difference as to which order you plug in the controllers to the USB hub - under normal conditions, I had the far left slot open, the second slot for my keyboard dongle and then the controllers plugged into the 2 ports on the far right.

When I was testing my new image, I had the bottom opened up and the unit was upside down. I plugged everything in the same as before, except in reverse (since it was upside down). As soon as I rearranged the plugs, all worked as usual.

@meleu thanks for responding, I've added my different controllers now, sorry for not doing this earlier. However I don't think this is of any importance since every controller (except for my bog standard keyboard) gives the same results.

@gautchh Attach and config a keyboard in ES, go into the emulator of your choice and enter the rgui menu. There you can navigate to Settings, Input and configure your controller. Make sure the right controller-device is selected and try bind all.

If your controllername does not show up increase the number of players (or devices) under Input and try again.

Another way to get your controller working properly is using xboxdrv, which emulates an xbox controller and makes mapping it in games easier.

@Ghost-Note

I didn't no, but it depends on your controller. You would have to modify the pins to pick up 4 players.

@Mihto 3rd party / clone ps3 controller support is limited at best - i would recommend getting another controller tbh (which you have done).
