From the documentation: Stella is a freely distributed multi-platform Atari 2600 VCS emulator; originally developed for Linux by Bradford W. Mott. Stella allows you to enjoy all of your favorite 2600 games once again by emulating the 2600's hardware with software. Stella is written in C++, which allows it to be ported to other operating systems and architectures. Since its original release Stella has been ported to AcronOS, AmigaOS, DOS, FreeBSD, IRIX, Linux, MacOS, OpenStep, OS/2, Unix, and Windows.
