As of January 1, 2017, the Stella project has moved to Github at https://stella-emu.github.io. As well, the codebase now uses Git instead of Subversion, so any developers must checkout from Git from this point forward. The new webpage includes instructions on how to set up Stella and Git. Developers can go directly to the Github devel page at https://github.com/stella-emu/stella.
If you reached this page from another website, please consider telling that website to update their links accordingly. This page (and all Stella-related items on Sourceforge) will be removed in approx. 3 months.
Thanks for the support,
Steve A. and the Stella Team
