I'm not sure it's all on LaunchBox. I managed to get it working with Pegasus FrontEnd, because it lets you send the file location as a ContentUri. However, that required a change to ppsspp, because they were expecting differently formatted ContentUris. We'll see if my pull request gets accepted. In case the developer sees this, here is the commit where Pegasus FrontEnd added ContentUri support. I'd try adding it myself, but I think LaunchBox maybe isn't open source?

Are you using Android 11? I'm getting the same thing. I've read that android has changed the way that file information is shared between applications. Here's what the developer of M64Plus FZ had to say about it: https://digdroid.com/forums/discussion/9140/android-11-scoped-storage-saf-support
