Hello, is there by chance a way to load a single game with the command line for the scummVM core? I would like to try and have it implemented into the retroarch rlauncher/hyperlaunch module. Maybe it could work by calling the shorthand gameid for an entry from the ini file?
Also if possible this would be great for other frontends.
thank you very much for that 
So I got the command working, but unfortunately it just goes to a black screen. I can hear game audio, and the controller sounds like it’s working, but no visual. I tried with a few different games. It’s the same on all of them. I can also use the same files on the dosbox core and it works perfectly.
I have a file named dig.rom inside that file I have the line “dig” with quotes. It does not seem to work without quotes.
The command I used to call retroatrch is: retroarch -L “C:\Emulation\Emulators\RetroArch\cores\scummvm_libretro.dll” “C:\Emulation\Emulators\RetroArch\dosgames\dig.rom”
My setup Win8.1x64 RA stable 1.2.2 newest core Intel cpu.
Any ideas?

Same problem here
I had the same problem on Android.
Could you test this: When you have the black screen, try pressing the keyboard / gamepad shortcut that makes it go into the ScummVM Save / Load screen (i think the default key is the “Select” button). Does the green Scummvm Save / Load screen appear? If it does, try returning to the game and see if the graphics are then working.
If this works, then you have the same problem I had. I think it has something to do with the graphics not being properly initialized when launching a game directly. If you do something to bring up the ScummVM GUI then the graphics are initialized properly. I’m not sure what the real fix would be, but I hacked a temporary solution in my installation, where I bring up a short GUI message (so fast you shouldn’t detect it) before the game starts which seems to initialize graphics properly.
Patch attached.

I can confirm this does resolve the issue. Switching to the scummvm save screen does show the gui and resuming goes right into video. 
Awesome find.
Diablodiab: any chance of compiling a version of the scummvm core for x86_64 that includes your patch?
Thanks again for this.
Also have you noticed any of the sierra slow downs or choppy dropouts on the android core?
I haven’t noticed any slowdowns - could you give an example of what to look for?
Sure thing, basically if you load certain games. In my case, Kings Quest V, Leisure Suit Larry 5. They drop to 0 FPS every 15 seconds or so. The game pad and retroarch become unresponsive during the drop outs and lasts about 5-10 seconds each drop out. So it feels like retroarch is freezing.
It is also described more in this thread by other users: http://libretro.com/forums/showthread.php?t=3776

I noticed you committed this patch a few days ago: https://github.com/libretro/scummvm/commit/b284380ea563edbd90f37d37df49e0b0a9c5aa1e
Thank you for that! I tried it with the latest nightly for windows64 and I am still getting the black screen. Did your patch make it into the newest win64 1-2-2016 core build?

I’m not sure. The current nightly ScummVM core was compiled on the same day that the patch was committed, so you might have to wait for the next time the nightly build is updated.
Ahh, I will wait for the next build and report back. thanks again
Try the latest build now and see if it works
I can confirm It is working!
