Dingoonity.org

I downloaded and converted a load of CPS2 games.
When I tried to open them on the Dingoo there was no files in the folder, having gone through the "interesting games" option.
Then I realised I had somehow deleted the CPS2 folder that's in the root folder. I downloaded the CPS2.sim file again and placed it in the root.
Still no joy

Any idea what the issue may be?

The CPS2.sim should be placed in the GAME directory.
You might have to Update Jukebox from the music menu too.

That's actually where I've had CPS2.sim all along.
Only had my Dingoo for a day so still not used to the folder structure.

Updating the jukebox fixed the problem. Thanks for the help!
