I got some controls working with AdvMame. I need to go through and get a few pages on the AdvMame configuration settings, since I wasn't sure what to use to specify controls for the trackball or spinner. I also had a problem because my "Coin One" button pauses the game no matter what. This leads to funky issues. For instance, on one game, I kept trying to put in a coin by pressing that button and it just paused the game. On another game, it would add a coin to the count, but also pause the game until I pressed it again. I also found that AdvMame can read a keyboard as if it's two controllers. Since I can change my controller from "B Input Mode" to "Keyboard Mode" (I'm guessing "B" means "Button," but I don't know.) From what I can see, just reading the TAB menu on AdvMame, I might have success using Keyboard mode and letting the keyboard act like two controllers. That also raises another question I'm going to have to spend time searching for: Mame-Libretro(2003) vs. AdvMame. Do I keep both on the system? I'm not sure if they'll both work consistently with the controller in one mode. AdvMame seems to work better, including using sound sample files easily, and the ROM set that works with AdvMame has more games in it. But that's a whole other issue to explore. Ideally I'd like to get my controller working in Keyboard and B Mode in both AdvMame and Mame-Libretro, but if I can get it to do everything in one form, I'll call it a day.

We don't support 3rd party images or systems bought with RetroPie - https://retropie.org.uk/forum/topic/3/read-this-first. Selling RetroPie is against the project's license. If you'd like to use RetroPie, get one of the images from retropie.org.uk/download and then follow the installation instructions from the Docs to use it.

@mitu Ho right, 3rd party! Yes that sound fair. Ok thanks!

Correct. Just for sanity checking, I'd see if you have any downloaded content in ~/.emulationstation/downloaded_images or gamelists and if so merge them with your current one on the USB drive - copy the images to the right folders, and you'll need to manually edit the gamelist content with a text editor to merge it. This will have been one-off scrapped content, though, so I don't expect it to be much. Edit: oops, I see you already did it.

So I haven't gotten this working. When I boot up, it shows things like... SSH: Process Not Found Then it gets into a ZMAP process that I cannot get out of so I am not able to run sudo apt-get update. Where are the files for the processes like SSH found in the folder hierarchy? Thanks!

Did you get a change to try this? Was it successful? I did the same thing haha. Have yet to try this solution.

@FrustratedUser Glad to hear it.
