Dendy Vs NES Any Help?

You can add your own system - see this page in the docs on how to do it. As for the image itself, it depends on the theme. Some themes use a variable to get the image so it might be enough to drop the image in the theme folder - but that's really up to the theme you're using.
Try first to get your system to work in Emulationstation and with your emulator and then we'll see about the theme.

The alternative would be to create a custom collection for the ROMs - this way you don't have to modify anything in Emulationstation's configuration file and you'll only have to handle the theme. Your Dendy ROMs will have to be in the NES system and they'll also appear there.

First Thank you for pointing me in the right direction. I have no idea how I overlooked the docs page. I still seem to be having an issue I was unable to find the es_system.cfg files at the site that is said I should find it. I am guessing via network it would look like this \retropie\config\all\emulationstation. However, I do not have the file. So I thought to myself no big deal I will just make the file, and I did but when I rebooted my pi it did not see an area that said Dendy. I am guessing if I do not have an icon or theme for Dendy that part would just be blank??

Not only that, but also the system's background probably will be unfilled. You can check in the ES log file (\\retropie\config\all\emulationstation\es_log.txt) for any errors on missing artwork.

@mitu yeah so I'm not getting anything showing up at all. I even changed the theme of RetroPie back to Carbon just to be safe. I am guessing it has to do with the homemade es_system.cfg file I made. The only thing I added inside of it was the Dendy system info... Any ideas? I found an es_system.cfg file from a pre-made image I was thinking about trying it, but I don't wish to harm my image in any way as it is a 400gb SD card and it would suck to rebuild it. I know I need to back it up, but good lord that is a ton of drive space.

@Cyborgbob Without a log file and/or a screenshot to show the problem, it's hard to guess what the problem is or suggest a solution.
Post your modified cfg on pastebin.com and the log file at least.

So the log seems really short so I hope it is cool just to post it here:

lvl2: EmulationStation - v2.7.6rp, built Jan 5 2019 - 22:02:06
lvl2: Creating surface...
lvl2: Created window successfully.
lvl2: Added known joystick Microntek USB Joystick (instance ID: 0, device index: 0)
lvl2: Added known joystick Microntek USB Joystick (instance ID: 1, device index: 1)
lvl2: Checking available OpenGL extensions...
lvl2: ARB_texture_non_power_of_two: MISSING
lvl2: Loading system config file /home/pi/.emulationstation/es_systems.cfg...
lvl0: es_systems.cfg is missing the <systemList> tag!
lvl0: Error while parsing systems configuration file!

Here is a copy of the es_system.cfg like I said earlier I did not have one in the spot that the link told me to look so I made my own only adding the info I wanted.

And here is a copy of the message my pi gives me when I try and boot with the modified es_system.cfg file in.

Cyborgbob

Forgot to add. I am guessing that the es_system.cfg file can be found in two places. One can be accessed via the network like the roms can be and the other maybe only from like a Ubuntu or Linux OS? This is just a guess. I am also guessing that I need to get the full copy of mine.(no idea how to do that BTW) and make the changes to it, Then I should be able to make my changes.

All of that is just guesses... The thing that has me really knocking my head around is the emulator..... I know nothing really about code. But I can read and I see nothing in the edits to the es_system.cfg file that points the roms to an nes Emulator.

@Cyborgbob not only do you need the <system> lines for that system, but you need the beginning and end <> info for the whole config

mitu

@Cyborgbob The file is - largely - incomplete. You need to get a copy of the system's config file first and modify it. As the page I indicated says, you need to copy the /etc/emulationstation/es_systems.cfg to /opt/retropie/configs/all/emulationstation first, and then modify the file.
The /etc/emulationstation/es_systems.cfg is not available via file shares, you must exit Emulationstation and copy it with either the file manager (type mc) or directly from the commandline:

cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation

After doing that, you'll see the complete file via File Shares and you'll be able to add your modifications - like the doc said.

@mitu Sweet. I think I understand. Thanks However I am Not sure YET how to make that happen, but now that I understand what I need to copy and where I need to put it. I guess I just need to learn how to use the file manager. I am assuming you mean the one that is built into Retropie?

Cyborgbob

@mitu So I could not figure out the built-in file manager I think really it had to do with the wireless keyboard I was using. However, I used a program called WinSCP. Long story short I got it up and running. Thanks so much for all your help. Now I just need to add some cool icons.
