Ares v129 has now been released. As seems to be the recent trend, Rasky has once again contributed a significant amount of improvments to the Nintendo 64 core; among other things, even allowing the Nintendo 64 port of Linux to boot!

Additionally, this release adds preliminary emulation of the Atari 2600. This is notable as it is our first new emulation core since we have taken over development.

In it's current state, many games are working but with the following caveats

1. Only a small subset of mappers are supported
2. The TIA isn't cycle accurate yet; a number of games may have rendering and/or collision issues.

There is currently little-to-no reason to use this over other Atari 2600 emulators at this time, but going forward we expect the situation to improve.
