I posted this in the ao486 forum, since that's the core I'm having issues with, but I think it's more of a MiSTer issue.
The ao486 core just plain doesn't show up in my core list. The core is on the SD card (I FTPed to verify). All the folders are there. But I can't select it in the core list. I've had it working in the past. I've tried running the updater script to see if that helps, but it doesn't.
Any suggestions?
Edit: Problem has been solved in other thread. I don't know how to delete threads, but you can ignore this one.
