Fragger has updated his site with this news:

I was planning to make this release at the same time of the final JoyMenu release, but there are a few things I still want to polish in JoyMenu.
The old license for JoyConsole sucks so I decided to release this version in the public domain.
The main change in this version is that the JoyConsole’s variables aren’t stored in the saves anymore.
