Troubleshooting

Are you having any problems, errors, crashes, games won't load, something is wrong?

Most of those issues have a known solution already.

Please check the troubleshooting steps below before asking for help in our Discord server.

If none of it helps, here's how to ask for help.

Troubleshooting

EmuVR freezes/crashes on startup or take ages to load

You added too many games. Try using 300 games max. Pick your favorite games.

Each game will generate a small texture for their labels, even if it's just text and not a custom label. You've maxed your video card memory limit with all those label textures.

This will be improved on later.

There are no consoles or games in the inventory menu

That means you did not scan your games, or the Game Scanner couldn't detect any games. Check if you added your game folders correctly, and your games are in the correct formats.

Everything was working yesterday, but now the games won't work anymore

Try restarting your PC. Seriously. Also, be aware that shutting down doesn’t fully shut down Windows 10.

My game won't load, the console shuts down after 3 seconds

First, make sure you can make the game work when you try to run only retroarch.exe with it. That means running your Retroarch installation inside your EmuVR folder.

If the game doesn't load in Retroarch, it won't load in EmuVR.

You might be missing the core's BIOS files. You might be using wrong file formats for that core.

Look up the docs for that libretro core, it will help you figure out what's wrong. Example: https://docs.libretro.com/library/beetle_psx/

Finally, try a different core.

OK, it works in retroarch.exe, but it's black in EmuVR, no video, audio only

Try another core. If you still can't get any to work, try other systems and more cores.

Some cores just won't work for some people in EmuVR, and we're still investigating why. That usually is an issue with AMD video cards. Most of time there is an alternative core for that system that will work for you.

This is happening specifically with Dreamcast!

You're using an older Reicast core version.

To update your Reicast core: delete "EmuVR\RetroArch\cores\reicast_libretro.dll" and click "Download Missing Cores" in the Game Scanner.

The screen says some file is missing

You're missing your BIOS files.

The emulated games are slow/stuttering

There are a few possible fixes. Open Retroarch.exe and change the following settings (try one at a time):

1. Enable Threaded Video (this will fix the issue in 90% of the cases)
2. Enable Hard GPU Sync
3. Enable or disable Vsync
4. Set Vertical Refresh Rate to 90 Hz

EmuVR runs great in desktop mode, but is very slow in VR mode

(This means the VR environment is slow, not the emulated games.)

This is a rare issue that sometimes can be fixed by lowering your supersampling settings a bit.

Here's how to do that for Oculus and for SteamVR. Try changing it to 0.9 or 90%.

Another possible fix is to try manually running EmuVR from the Force Oculus.exe or Force SteamVR.exe files.

I can't extract retroarch.7z / it's corrupted

Don't use WinRAR, use 7-Zip.

I tried everything above but I still have problems, help!

If nothing above helped fixing your issue, you can ask for help in the #troubleshooting channel on our Discord server, and someone will help you figure out how to make it work.

Here are some useful information that you can provide when you ask for help:

• Are you in desktop mode or VR mode?
• Your VR HMD
• Your video card
• What cores are you using
• Which troubleshooting steps above did you try?

Be precise on what's happening for you: "It doesn't work" and "It crashes" won't help.

What exactly is not working? EmuVR? The emulated games? How is it not working?

Does the console turns off after 3 seconds? The games run on Retroarch but not in EmuVR?

What exactly do you do just before you see the problem happening?

If someone asks you to take a screenshot of some of your folders, please enable your file extensions before doing that.
