      @tmntturtlguy I decided to use 4 options so I could use an overlay with an additional transparent filter which gives a shine or glare on the screen.

        Can you guys post your scripts on ghostbin (or something similar) instead of meganz? I'm unable to see the script on my phone when it's on meganz.

          It's ... well functional but a huge list with cp commands.
          I would prefer your approach as it is the easier way without copy file -->> much better.

          @FlashPC
          Use submenu and case selection to get it functional calls

          Mean...
          Main list is SEGA CD -> Select overlay, shader..... for SegaCD

          #### THIS IS PSEUDOCODE!!!
          
          modemenu ()
          {
          until [[ $shaderchoice == "<--" ]]
          do
              shaderchoice=$(whiptail --backtitle " Choose " --title " Choose " --menu "Choose an option" 0 0 0 \
                  "<--" "... back to mainmenu" \
                  "standard" "Reset retroarch.cfg" \
                  "shaders" "Use Shaders...." \
                 .....
          done
          
          case "$shaderchoice" in
              standard) cp -f /opt/retropie/configs/all/retroswap/$1/standard/retroarch.cfg /opt/retropie/configs/$1/ ;;
              shaders) cp -f /opt/retropie/configs/all/retroswap/$1/shaders/retroarch.cfg /opt/retropie/configs/$1/ ;;
          esac
          done
          }
          
          #----------------------------
          
          while true
          do
              syschoice=$(whiptail --backtitle " Choose " --title " Choose " --menu "Choose an option" 0 0 0 \
                  "nes" "Nintendo Entertainment System" \
                  "md" "Sega Megadrive" \
                 .....
          done
          
          
          case "$syschoice"
              *) modemenu "$syschoice" ;;
          esac
          done
          
          

          This will shrink your code to minimum :)

            Wow! Pretty huge. It can be simplified, but if it works, then fine. I could help, but it seems to be a very specific script to @FlashPC needs. I'm not sure about the details in his config...

              Hey guys I've filled in the script that @cyperghost posted and I kind of understand what is trying to happen, but Iam stuck as to what I am missing, I don't know how to add the nice black boxes but I've entered it into ghost paste here

                Here is a working script!
                As I said --- it's was pseudocode with some errors
                2x done without do, break condition was set wrong, dialogboxes showed unneeded options....

                If you run this script you will see just 3do standard for ex. as output.. Therefore
                You must exchange the commands in line 49-52 with your copy commands.

                So you stripped down from 30kB to 3kB and can faster navigate ;)

                Greetings fly out to @meleu (<--- this guy is responsible for my rising interest in bash) and @TMNTturtlguy (<--- this guy is responsible that I get in need to use bash ... EUREKA!)

                    @flashpc Does it work for you?
                    Can you post the full script with all alterings please?

                    You can even alter the titles and backtitles of each menu for ex. like this --backtitle " Your selected console is ${1^^} " So you have an overview of your systemchoice if you want to exchange the shader. Just a convenient addon...

                    ... There is a small bug Please add a return between line 53 & 54. I update code.

                    What is the difference between overlay and overlay-real?

                      Greetings back to you @cyperghost! Hope all is well. I just come up with crazy ideas, and pretty down and dirty ways to try to make them work, you and @meleu are the true artists that clean up the messes I start!

                          @cyperghost I would like to recommend this reading when you have a time: Importance of code indentation. ;-)

                            I found that out, does the additional return clear the $shaderchoice variable? I just added "shaderchoice=" at the start of the modemenu routine and that allowed me to select another mode after returning the main screen

                            overlay has side art and a bezel around the screen, overlay-real is the same with an additional semi transparent layer over the play area to mimic sun glare and smears on an old CRT TV

                            The current script is here

                            Thanks again

                              haha! I tried to be an artist. I even created a blog with some drawings I made: https://meleuartblog.wordpress.com/

                              Stopped updating that 2 years ago...

                              @FlashPC sorry for this off-topic post on your thread. :)

                                @meleu Hehe... I like artists ;)
                                Drawing is good for relaxing and maybe once a time you come back to design studies. Believe me I've married a talented artist - my wife do great drawings if there is muse. You can do also good scratches with Corel Painter and a small Bamboo Tableu.

                                Btw.: This one is epic ;)

                                @FlashPC

                                I found that out, does the additional return clear the $shaderchoice variable? I just added "shaderchoice=" at the start of the modemenu routine and that allowed me to select another mode after returning the main screen

                                Yes that also helps, maybe it helps to declare shaderchoice as local variable.
                                You did a great job ;) Even if the coding is a bit "uncommon" ;) You use tons of if-then clauses to set a variable. Please don't see this as an offence but now you have to maintain two locations of systemnames. It's better to use an array for this and to create the menu out of this, too. But as the script works for you it's okay ....

                                  @cyperghost Thanks man, I'm an absolute noob when it comes to this type of coding, I know it's uncommon, but following the information and instructions from various sources I'm finding its a little bit disjointed and I've done some BASIC self training back in the 90s and recently Lua for creating (very simple) programs in windows.

                                  I know of if / then clauses and so it meant I could a load a variable with text depending on the selection. But I want to take this further as a pet project and a learning exercise.

                                  This is how I started with Lua (indigorose auto media studio), I started with a basic idea and then added to it, tidying the code, adding features, and streamlining by searching forums and checking YouTube.

                                  Any learning directions would be definitely be appreciated, I will never be a master but if I could muddle through it would be great

                                  Cheers guys

                                    @flashpc Yes the coding style looks like BASIC... btw - you can install FreeBasic on the Pie and create binaries out of this. So if you want to share your programms the other users don't need an interpreter. So you can stick to any language you want... bash or BASIC.

                                    But I did not know about whiptails --notags command. So your systemlist looks really tidy ;) If you don't like whiptail you can stick to dialog. Dialog is a more expanded box creater as whiptail with much more commands but I prefer whiptail because of it's simply usage.

                                      Thanks dude, I found it because I was looking for a way to remove the OK button and read the info for the whiptail command and thought --notags would be interesting.

                                          I think it can be done much easier without in need for a settings variable.

                                          I write some pseudo-code okay

                                          
                                          # Your array
                                          console=("3do" "Panasonic" "nes" "Nintendo Entertainment system"......)
                                          
                                          # Now let whiptail work for you... as it expects two strings for creating text boxes, we give them...
                                          
                                          # I try to use proper indentation for better code reading
                                          # We start our loop for systemchoice here

                                                      esac
                                              done
                                          

                                          Later you can get real systemname out of array with ${console[$1]} (I hope so) ;)

                                          EDIT:

                                          Add this to function modemenu

                                          local idx=0
                                          until [[ "${console[idx]}" == "$1" ][
                                              do
                                                 idx=$(( $idx + 1 ))
                                              done
                                          

                                          Then use whiptail and higher idx+1 and you've the console name... That's it and it was funny ;)
