Lol, sorry for the confusion

I was just referring to an AF thread here, where it first was speculated that there where one version for older mods and another for newer ones, which weren't interchangeable, but that was a misunderstanding - anyway not really important, and I just thought you where referencing to that with your comment
Nowadays, the AF devs have dropped having both stable and nightlies, and now only have one version(stable) which is downloaded from there forum(though also older versions available too, if having issues with the newest). It's not an installer, and still a bin file, which should be used together with NFEtools, also downloadable from there forum, which includes a firmware flasher also.
Sorry, i'm not 100% certain, but I know the flasher checks which mod it is first, because it needs to change some of the configurations at times which works differently for the different mods. Also, one time I saw they added recognition support for some new mod and someone rejoiced on there forum, but then they stated it could still not be flashed, but was only preliminary recognition support added, hence why i'm pretty certain it wouldn't flash unsupported devices.
Anyway, trying to help someone is never wrong in my book no matter what
