We’ve been trying to get out nightlies for as many platforms.
Recently we added OSX (64 bit) and iOS nightlies, as well as 3DS and PS Vita.
This week we’ve added cydia and f-droid repositories to out buildbot. These builds are on the bleeding edge, usually a few minutes behind the latest commit.
The URL for the cydia repository is: http://buildbot.libretro.com/repo/cydia
And the URL for the f-droid repository is: http://buildbot.libretro.com/repo/fdroid/repo
The Android builds are signed with the same key as the nightlies so updating from those should be seamless.
Alternatively you may scan these to get the URL:
Note: We know it’s not working on iOS9
