Hi, I’m sure we’ll get the controllers working. Btw, the mentioned out-of-the-box-experience works at least for wired mode (via USB), but probably not for Bluetooth as you discovered.
In what way do the controllers not work with 2.7.4dev? Do they not appear at all? Can you configure them with the configuration tool in FS-UAE Launcher? Please provide some more information about this, and if you could also send fs-uae.log.txt to frode@fs-uae.net I’ll take a closer look!
