Black Screen when launching Cemu games.


Recommended Posts

Hi everyone. I will try to explain my problem...

When launching a cemu game with no starup screen enabled the game just starts fine.

But if startup screen is enabled, the game launches, but i can only hear the sound in the background and a black screen is all i see. The game is running because i can hear it, but for some reason it doesn´t show on screen, its like running behind some black screen.

Does anybody knows how to fix this? Thank you.

Cemu should work with startup on. Running ok with my setup.

What version Cemu are you using? Are you on Win10?

Try checking either (or both) the "Aggressive Startup Window Hiding" or "Hide All Windows..." options.

Im on Cemu 1.17.4 running on Win10.

I tried Aggressive Startup Window Hiding and Hide All Windows, both selected and one at a time, but no luck, i will try again, maybe im missing something

OK. I haven't bothered with Cemu in quite a while so updated to 1.17.4 and still works fine with the 3 games I tested. Here are the settings I have. Admittedly I have not tweaked any graphic settings in Cemu in quite a while as well so maybe it could be a setting directly in Cemu causing the focus loss.

I have the same problem with the black screen and im using cemu version 1.22.6c and I also dont know where you guys got the edit emulator screen

Its in Launchbox. Go to >Tools>Manage Emulators. Choose Cemu and edit it.

Hey guys. I dont have this problem but you could try the following...

In LB, go to tools, Manage Emulators.

Select Cemu and open the "Running AutoHotkey Script" tab.

Copy and paste the following into the running ahk script tab

SetTitleMatchMode, 2

loop 20
{
	Sleep 500

	if WinExist("Cemu")
	{
		Sleep 1000
		WinActivate
		break
	}
}

 If you already have some code in the running ahk script tab,  place this^ code at the top above anything else. 

Just to explain a little what is going on with this code.

"Loop 20"... the code within the squirrely brackets will loop 20 times.

"Sleep 500"... wait half a second between each loop.... these 2 commands combined is essentially a timeout of 10 seconds. 

"if WinExist"... If a windows titlebar contains the word "Cemu" then "WinActivate", bring that window to the front.
