      @sliver-x ok then I'll have to add it back as I believe I overrode the one in /opt since I added emulators that did not show up. That answers my question thank you! I can amend one to the other. That should fix it.

        @sliver-x hmm well I checked and it's the same yet I only see the default menu items that come in a standard install weird. Any advice on adding them back?

        Edit: scratch that in an idiot and was looking at the standard retropie settings I see the entry adding it back now lol.

          I can't seem to open the .img file. Windows Imager and Imageburn both give me an error that the file is corrupt or unrecognizable. Anyone get that when they try to image the SD card?

            @azfunguy are you trying to install the image? Why not use the official raspberry pi imager? It's painless.

              Does anyone know if it's generally safe to update the OS if needed? Or should we stick to only updating the emulators and packages.

                @sliver-x I love the theme, it works and looks fantastic in my GPi with the zero w 2. Is there a reason Neo Geo Pocket is not a system? I noticed Neo Geo Pocket Color is and the roms show when I add them, just not the original Neo Geo Pocket.

                EDIT: I just added it to the es_systems.cfg file. No big.

                  Unlike the Wonderswan/Wonderswan Color, where there were quite a few black and white only releases, there was, IIRC, 10 non-color NGP games ever released.

                  Due to this I've never treated them as separate systems on any emulation setup I've made. I have both .NGP and .NGC extensions set up for EmulationStation, so both are detected and handled by the one "System".

                  @killj0y1

                  Upgrading should generally work (I was able to do a full upgrade of everything from the state of 12/31 to day before yesterday fine), unless dtbo files get updated, then either the LCD or sound will have issues without manual intervention to fix. This would be the same case for any OS image for the machine, not just mine, due to how the LCD/etc hardware needs patches to function correctly.

                    I just made some mods and opened up the hdmi port. I wasn't able to use it successfully though. Any tips? I'm gonna try another tv since I know mine tho new can be wonky about it. I tried a few different ways but didn't have any success. Nothing broke but it just didn't care for displaying. I'm using a straight cable for testing. I'm gonna try other tv's tomorrow but so far no luck. I'm hoping it's just my tv since I'd never use it personally on my own tv having an rpi4 rig with synced saves.

                      @killj0y1 you changed the config txt file and got rid of the dpi display settings?

                          @killj0y1 ah okay if you did edit the config txt already back to using HDMI then that's my idea gone. So the gpi case patch comes with the original files and the patch files. Just pop the original config.txt back into the boot directory and that should allow the pi to boot into it's default HDMI mode

                            This image has a custom config.txt that the HDMI scripts edit in place to replace the (crude) functionality the original GPi Case patch performed.

                            When you enable HDMI out under the Advanced Settings menu, it removes a block of text that sets up the A/V over the GPIO pins, allowing the HDMI output to work at next reboot. When/if it detects the cable has been unplugged, or the HDMI toggle script is ran manually again, it adds it back.

                            Replace all text in config.txt with the following to set it back to how my setup expects it to be:

                            The HDMI scripts should work now. Unless you deleted ~/gpihdmiout, in which case, you need to put that back since that's where the scripts themselves and the required dtbo files live.

                            If not, not sure what you're running into; I've gotten it to work with 8 different TVs and monitors so far.

                              @sliver-x ok got it but can I still add an overclock or will your script just refuse to work if anything is set differently. Really only would edit that and overvoltage. So long as it works but way you described I'm happy with that.

                                "enable.sh" takes a backup of current Retroarch config files and EmulationStation's config then restores the HDMI mode copies of them if they exist, deletes the text between the #####gpizero##### markers in /boot/config.txt, copies /home/pi/gpihdmiout/hdmi.dtbo to /boot/overlays/dpi24.dtbo, blanks the file /etc/asound.conf and sets the default sound device in EmulationStation to HDMI.

                                "disable.sh" takes a backup of current Retroarch config files and EmulationStation's config then restores the LCD mode copies of them if they exist, adds the text between the #####gpizero##### markers in /boot/config.txt, copies /home/pi/gpihdmiout/lcd.dtbo to /boot/overlays/dpi24.dtbo, builds a copy of /etc/asound.conf that performs mono downmixing of the audio and sets the default sound device in EmulationStation to "Headphone".

                                So long as nothing you set in config.txt conflicts with something "disable.sh" or "enable.sh" is writing to config.txt, or trying to do custom ALSA configs via /etc/asound.conf, it shouldn't matter what you change, the scripts won't touch it.

                                  @sliver-x ok awesome and I'm assuming you appended everything to the config.txt on the boot partition or is it stored elsewhere?

                                  Edit: nvm I got what you meant in the first post. Swap it completely and let it do its thing.

                                  Edit2: I think I know what the problem might be. Your original es_systems.cfg I disabled to use the updated (I installed more systems that didn't show up) in /etc vs /opt. I wonder if that's what's causing the problem I'll try and copy it over and see if that does the trick. I'll also check out config.txt to see if it matches what you posted.

                                  Edit 3: yup config.txt matches. Moved over es_systems.cfg to match in /opt gonna try it out.

                                  Edit4: yea no dice even tried another tv. Config.txt seems fine I'll attach it if I can or just add it to this post. Otherwise everything else seems fine the gpihdmi folder you mentioned is there and I even took a look at the script and nothing it references was changed. So odd.

                                    @sliver-x also noticed that samba shares arent persistent after reboot but I didn't see a toggle for it. Dunno if that's intentional for power saving. It's not a big deal since I just reinstall it and it takes 2 seconds and it works. Not something I need often anyways but just curious.

                                      @sliver-x ok after testing with a bone stock raspbian image to see if it's hardware or software. I tried stock raspbian on both my pi zero 2 and zero 1 and a lot of back and forth and I found it was the cable I had cut it back to make better contact but it seems not enough even though it seemed to fully fit in. So that's solved. The samba thing is still a mystery. Thanks for the help 🤘🏻

                                        Samba and all associated services are disabled by default. I wrote a script to toggle this; are you using it or doing this through raspi-config?
