Stella v3.6 (r2423) is released. Stella is a multi-platform Atari 2600 VCS emulator. The Atari 2600 Video Computer System (VCS), introduced in 1977, was the most popular home video game system of the early 1980's. Now you can enjoy all of your favorite Atari 2600 games on your PC thanks to Stella!

Stella v3.6 (r2423) changelog:

* Added support for 2600-daptor II device, including native support for 7800 controllers, BoosterGrip and Keypad controllers. Special thanks go to Tom Hafner for a complimentary test sample of this device, and also for donating a BoosterGrip controller. * Added ability to dynamically swap the port order of Stelladaptor/ 2600-daptor devices with the 'Control-1' key combo (useful if you have only one 2600-daptor and want to use it as a left port normally, but as a right port for Star Raiders, etc). * Added CompuMate bankswitching/controller support to the emulation core; the Spectravideo CompuMate ROMs (NTSC and PAL) now work. Frequently used keys on the CompuMate are directly mapped to your keyboard (ie, Func-Space for backspace is mapped to Backspace, etc). Loading/saving from the cassette player is not yet supported, and will come in a future release. * Fixed bug in BoosterGrip controller emulation; the functionality of the booster and trigger buttons was reversed. Related to this, renamed these actions in the Event Mapping dialog to be more clear. * Reverted to SDL 1.2.14 for the Windows 98/2k release, since SDL 1.2.15 isn't supported in that environment. * Updated included PNG library to latest stable version.
