Atari - 2600 (Stella 2014)

Background

A port of Stella, the Atari 2600 VCS emulator, forked from the main Stella codebase around 2014 (Stella 3.9.3). It is a snapshot of the features, compatibility and performance of that time and misses many later accuracy improvements, but runs significantly faster - use it where the up-to-date Stella core cannot keep full speed.
