Apple II not appearing in emulator menu

[Laguna Hiker]

I am posting a solution to an issue I've been wrestling with, because I haven't seen it posted elsewhere. I had a problem with the Apple II emulator not appearing in the Emulation Station carousel menu. First, I checked for the obvious fixes:

1. Confirm that the linapple emulator was installed.
2. Confirm that I had Apple II ROMs in the appropriate ROM folder.

Neither of those fixed my problem. So I went to this file:

 /home/pi/.emulationstation/es_system.cfg

Note that linapple only recognizes ROM files with a DSK extension. That's the key to the fix.

I checked the system settings for the emulator (they're listed under 'Apple 2'), and I noticed that in the <extensions> tag, .dsk and .DSK extensions (which are the ones that linapple recognizes) were missing. So I added them to the <extensions> tag and rebooted the RaspberryPi. That did the trick.

It appears that linapple wasn't appearing in the Emulation Station carousel because Emulation Station thought there were no Apple II ROMs installed. And that's because it didn't know that DSK files were Apple II ROM s. Adding the extensions to es_system.cfg fixed that problem.

Hope that helps other folks that run into the same problem!
