Whenever I try to start a game, the message “Failed to start the content” appears.
I added all the bios that the core operates requires.
I entered the site: “https://docs.libretro.com/library/4do/” But I didn’t find any additional information.
I’m using an .cue extension iso.
I tried to add other video drivers but without success.
I copied the contents of the “retroarch-log” file (attached).
Could you take a look and tell me where my mistake is?
I don’t see the core being loaded in that. If you try to load it via ‘load core’, does it actually load it? That is, does the core name appear in the bottom-left corner of the screen? or does it continue to say “no core”?
The core is loaded normally (attached photo).
I’m sorry but the log information being shown above was taken from the “retroarch-log” file. I’m not sure if the necessary log information comes from this file. Or whether I should obtain such information in another way.
Ok, that’s good. It means the core’s connection to RetroArch isn’t broken. If your games scanned into a playlist, they should be okay, too.
If you go to to settings > logging, are the logging verbosity settings at “debug”?
the games appear in the play list yes.
I can’t upload .txt files it is complicated to produce these pnj files at all times. Is there an easier way to show this kind of information?
Yes, in the settings > logging menu, set ‘log to file’ to ON and then take the resulting log file and paste the contents somewhere like pastebin.com and then post a link to it here.
EDIT: it seems to be having a problem with your cue/iso. Have you tried loading the iso directly? That is, instead of through the cue?
It worked!!! 
thank you!!!

Run the game directly through the iso.
But what is the problem with the .cue file?
Does retroarch have any incompatibilities or is it something on a computer that is not working properly?
Probably just something wrong with the cue. They’re frequently wrong.
