In order to successfully use KStella, you need at least KDE 3.0 and QT3.0. I have tested the latest version on KDE 3.2.0, so you may well need that version to use it.

Of course, to actually play any Atari games, you need the Stella emulator located at Remember, KStella is not actually an emulator, only a GUI frontend.

To really take advantage of all the features of KStella, you will need the game snapshots, labels, and manuals located on the KStella page. While these are not absolutely required, much of KStella's functionality will be lost without them.
