Someone going by the handle of Mupo dropped by the Exult project entry to let us know that Exult for Android (hosted thereat) works with the latest version of Google’s mobile OS:

Great news! I just got the android version working with JellyBean 4.1.2. I copied the stuff I had from my modded PSP after downloading the data that it wanted me to and then my save games. And THEY work too!!! So happy to have this game back! Thanks for hosting this!

I am assuming that he is referring to the native version of Android, rather than the Java-based version, but who knows? Maybe both will work with Jelly Bean!
