Cannot launch non-steam games if filename has spaces in it

[wonx]

I manually added a few non-steam games to my game list. I can run them from steam, either in desktop or in big picture view, and they launch and work. However, when I use moonlight from my raspberry pi, and I launch the same game from the Big Picture view, I get an error for those games who have a space in their filename.

For instance: Launching "C:\Program Files\Dolphin\Dolphin.exe" /e "V:\Gamecube\Mari Kart - Double Dash!! (USA).iso" Does not work. Launching "C:\Program Files\Dolphin\Dolphin.exe" /e "V:\Gamecube\The_Legend_Of_Zelda_The_Wind_Waker_USA_NGC-STARCUBE.iso" Works just fine.

I also tried with other games and other emulators, and it is consistent. On the other hand, spaces on the path to the game do not cause any issues.

Please provide the following info.

NVidia Geforce Experience version: 3.15.0.186 Moonlight Embedded version: Moonlight Embedded 2.4.7 Moonlight Embedded source: Used the script in https://github.com/TechWizTime/moonlight-retropie Moonlight Embedded running on: Raspberry Pi 3 Moonlight Embedded running on distribution: Linux retropie 4.4.50-v7+ in Raspbian GNU/Linux 8

You could use this simple workaround and stream the entire desktop:

• Go into your Nvidia Experience Application to the Shield Settings
• Add the Game C:\Windows\System32\mstsc.exe and call it Desktop or something like that
• Start moonlight with option -app Desktop

This is how I use moonlight myself every time and it works perfectly fine.

But then it would just show Windows' desktop? How could I launch the steam from there using a game controller?

Could you provide the command you used to start moonlight on your raspberry and the error message thrown by moonlight when you are using spaces?

[wonx]

I use this command to start moonlight on the raspberry: moonlight stream -720 -fps 30 192.168.1.121

This is the command used in Steam to launch the game: "C:\Program Files\Dolphin\Dolphin.exe" /e "V:\Wii\SUPER MARIO GALAXY.iso"

And his is the error message I get when I launch it from moonlight: https://imgur.com/a/aIu5akz

So thats not a moonlight problem. Seems like a Dolphin Problem. I dont know what Dolphin does or what it is but i suggest to rename the .iso files.

The same happens with any other path that includes spaces, not only Dolphin. For instance, if you try to launch a PS2 game using PCSX2.

The thing is that the launcher works just fine from Steam, but not if you start it from Moonlight.

Ok but when I get that correctly launching moonlight without an -app Option will automatically start Steam Big Picture Mode.

So everything that happens from now on is not affected by moonlight anymore. Moonlight only starts the video stream and launches a .exe in this case steam (Big Picture). Plus The error message in your images is returned by Dolphin not by moonlight so this has to be a Problem on your Windows machine.

So I would still recommend to rename the .iso files.

You could also try this:

• Add Dolphin to Steam Library via Add non-steam game
• In the Dolphin "game" properties add the launch option like:
  • --exec="FILE NAME WITH SPACES.iso" or /e "FILE NAME WITH SPACES.iso". (I would try both)
  • make sure you use the Set Launch Options... button and not simply add the options to the exe-target.

Then repeat those steps for every file you need this for.
