      Any chance of adding the retroarch cores for Dosbox and ScummVM?

      I would be awesome to use the retroarch video options and shaders with these cores.

          @tekn0 if you want scanlines in dosbox, the standalone dosbox already has it. Looks good to me.

              @tekn0 last I tried they were unusable, couldn't even navigate menus to run scummvm games. Generally speaking standalone emulators run better than the libretro cores. But if you can get them running by all means I'd like to see it

                @herb_fargus Interesting. I actually had good luck with them last year in windows x86. I will get them going again and try to make a video somehow.

                I remember working with the retroarch team so we could get scummvm games to load with a single file for creating playlists. This method bypassed the scummvm interface and booted directly into the game. I will try and find that info again. I played through many games using the scummvm core on a windows 8 machine and had no issues. I also used the dosbox core directly loading config files from the ExoDos collection with great success as well. Again this was all in windows on x86.

                  @tekn0 dosbox has a key repeating issue making it unusable for a lot of stuff. There was some other issue with scummvm - can't remember. I have retropie modules for both, so can add them to experimental perhaps if you want to try them.

                        @BuZz hmm, I would still be interested in testing. I just verified on my windows box I am able to load both scummvm and dosbox directly from the command line and boot right into a game with no issues. I also have a fully loaded scummvm.ini file for all games, paths, and settings used to call games directly from command line.

                          @tekn0 the dosbox bug a linked is specific to linux I think.

                            Also you can see scummvm running fine here on lakka for odroid.(

                            )

                              Im not sure if this is common knowledge or not so I apologize if it is. This info is not on the libretro wiki page so I am just writing it now.

                              Scummvm Libretro Core. (Windows Guide [Should Translate to Linux])
                              Running a scummvm game from command line you actually don't ever have to open the scummvm GUI. All you need is to make sure of is that the game is extracted, and has an entry in the scummvm.ini file like this:

                              [dig]
                              description=The Dig
                              path=C:\Emulation\ScummVMGames
                              gameid=dig
                              guioptions=sndNoMIDI

                              Then you need to make a small text file named after the short hand name for the game. This file only has to contain a single line of text that is also the shorthand name of the game.

                              Examples would be: "C:\Emulation\ScummVMGames\dig\dig.rom" inside of dig.rom is just the word "dig".

                              Then you would call the game direct from command line: retroarch -L "C:\Emulation\Emulators\RetroArch\cores\scummvm_libretro.dll" "C:\Emulation\ScummVMGames\dig\dig.rom"

                              This gets much easier if you have a pre seeded scummvm.ini file like this one and just edit the paths:
                              http://pastebin.com/CbmvqqYR
