Stella Version 3.7.3 Released

We haven't posted news about the exceptional Atari 2600 emulator Stella in some time, but thanks to its primary maintainer, Stephen Anthony, Stella continues to see frequent releases. Stella is a multi-platform Atari 2600 VCS emulator released under the GNU General Public License (GPL), and versions have been released for a wide variety of operating systems. Emulation is a great way to sample the large Atari 2600 library, including new homebrew titles being developed today. It's also a great tool for developers, as Stella has an excellent debugger built in.

The current version of Stella is 3.7.3. Changes in this version include:
  • Improved handling of 'illegal' VSYNC signals, which sometimes created 'short' frames that caused massive flickering. Also improved related behaviour when VSYNC isn't used at all
  • Improved sound generation with ROMs that have irregular scanline counts. This fixes many demo ROMs as well as Quadrun, where previously there would be 'gaps' in the sound output.
  • Improved emulation of RIOT chip, in particular the behaviour of reading from TIMINT. Also, D6 of the Interrupt Flag register is now properly set on active transition of the PA7 pin.
  • Fixed bug in DPC+ bankswitch scheme; the music in "Stay Frosty 2" wasn't playing correctly.
  • The ROM properties database now uses 'Auto' instead of 'Auto-select' everywhere. This makes for less typing when running from the commandline.
  • Updated included PNG library to latest stable version
