          @benjiman What is the problem that you're having ? Simply deleting one file might not solve it.

            @mitu I chose a default ROM and find out it won't run the game so I try and change it and it sticks as the 1st choice. I also can't remove ROM choice. No error messages just stays as it is.

              @mitu example if I chose mame4all I hope it works cause it's Going to stay on that ROM. I have heard it can be caused by adding games through a flash drive which is how I do it.

                @benjiman No, that's not the way you get a problem emulators.cfg. The file you seek is in /opt/retropie/configs/<system>/, where <system> is the name of the ROM folder.
                If you used the arcade folder for your ROMs and then, through the Runcommand launch menu, changed the emulator for a certain ROM, the file that keeps this setting is /opt/retropie/configs/arcade/emulators.cfg. To change its permissions (which seems to be your problem), you can exit Emulationstation, then run from the command prompt (using a keyboard):

                sudo chown pi:pi /opt/retropie/configs/arcade/emulators.cfg
                chmod +w /opt/retropie/configs/arcade/emulators.cfg

                        Hi! I know this entry is pretty old, but since I got the same problem very frequently I thought I‘d share what I did to resolve it, so people who might still find this thread during their search (as I did recently) have something else to try ;) On my system it really seemed to be the configs/all/emulators.cfg file which somehow got corrupted, and weird stuff got written to the file. If I opened it with notepad I simply had to remove that weird stuff/characters and then was able to write to the file again (e.g. changing an emulator for a specific rom, remove it again and so on). So I didn’t have to delete the file and lose all settings/changes made to it (which can be quite a lot). Maybe this helps someone...

                          @jackyracer Complete new here having the exact same problem. Could you possibly help guide me to that config file?

                            @Knuckles78 The emulators.cfg file is in \\retropie\configs\all - if you're using File Shares to access your RetroPie installation.

                              @mitu I’m accessing it directly through terminal. I attempted the “sudo chown pi:pi etc.” you posted previously with no results. Like I said I’m pretty new and I think it’s because I’m still in Raspberry pi rather than RetroPie inside terminal.

                                The command I posted works from the terminal. How are you checking that it's working/not-working ? You can list the rights on the file(s) by running:

                                ls -l /opt/retropie/configs/all/emulators.cfg
                                ls -l /opt/retropie/configs/arcade/emulators.cfg

                                  @mitu I love the ls -l look. Aside from requiring the extra characters that more than double the command's length it's great. XD

                                    @IanDaemon -l stands for "long listing format" with good reason. :)

                                      You can always create 'aliases' for long commands. ll is a oft used alias of ls -l, just add

                                      alias ll='ls -l'
                                      

                                      to your $HOME/.profile and that's all.
                                      Favorite command today apt-get moo.

                                        @mitu Thank you for your help, I’m taking the time to understand more about the terminal. I watched a few videos, and now what you’re saying to me makes more sense.

                                          @mitu /home/pi/.profile doesn't exist. Is that a file with no extension that I create?
                                          Nevermind. I just found the file. I couldn't see it in the terminal, but PIXEL could see itl

                                            @IanDaemon Files and directories with a leading . in their names are hidden in Linux. To list them with ls, use the -a ("all") option. You can combine multiple options after one -, so -l -a becomes -la (or -al, as the order doesn't matter for options without further parameters).

                                            ls -la
                                            

                                            edit: You could create another alias to list hidden files, e.g. lla:

                                            alias lla='ls -la'
