@Clyde I just added some small changed the the RetroPie scriptmodule, the hard work was done upstream, by the AttractMode developer.

It works !!!!!! but only when i launch ES in a terminal :-( This is exactly what I said in my first reply. This is how it's configured the RetroPie launcher - as outlined in the docs. Last question : does ES and Retropie need sudoers ? If not, i should modify authorization in /opt/retropie/configs : actually all files are for root:root and not for my user "pi" As runcommand try to write in the .cfg file, it couln't !!! The /opt/retropie/configs shouldn't be owned by root - there's something that you maybe changed, because the RetroPie-Setup scripts ensure the folder is owned and writable by the installation users. The sudo rights for the install user is needed for installing additional packages and for adding the necessary configurations needed for RetroPie. This is one of the first steps outlined in the installation docs.

@SinisterSpatula That's great indeed and I'm glad I could help. I can't wait to see the next iteration you produce. The advanced mapping method with case statement really works well if you have a lot of code. My arcade machine's runcommand-onstart.sh has about 4,300 lines of code for 4 arcade joysticks, a PS4 wireless controller and an 8BitDo Zero covering about 60 systems. I also use it for all of the libretro cores too now. It doesn't miss a beat, so I reckon you're going down the right path. Going back to my GPi vice code, with a bit more testing I'm finding that it's definitely not working for every game, so I reckon your newly produced code will be more successful than mine in "universalising" the controls for the c64. Please feel free to experiment with my code of course and make any changes you think are best.

@ectoone Aha! I changed it like you said and changed the color to 00000000 for good measure, and it worked just great. This will make me feel less weird about including multi-disc games. Thanks so much for your help!

@LionSquall read the sticky topics and open a new topic with info. This is a 3 year old discussion.

@darknior Wow bud.... You're all over the map, aren't you? Careful that you don't spread yourself too thin with too many projects at once. I did that myself back in the day and it literally drove me insane. :)

@NastyButtler322 if you go through the Retropie-Setup GitHub repository and search the individual installation script modules you'll find the references of all source code repositories for each of those emulators. Best of luck.

@Zigurana By lightweight, I meant from the user interface experience. The stock full allows for scraping games, changing UI settings, etc. My custom console I am making won't have any of that, and since it's already pretty stripped down in kid mode, I can just branch off of that and do my modifications, instead of redoing what has already been done. Now I just can't figure out how to get my changed PNG files for the default UI elements to be applied. Just changing them doesn't update them in source, and I think res2h needs to be used to convert them after they are created. I tried doing it on frame.png, which I changed, and now I can't compile so I am trying to resolve that issue. Just changing the .png and saving over the old one doesn't work.
