Stella v4.5 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 v4.5 changelog:

4.2 to 4.5: (January 1, 2015) * The conversion to C++11 has begun :) From this point on, to build Stella you will need a C++11 compatible compiler (Visual Studio 2013, Clang 3.3, gcc 4.9, Xcode 6, etc). Eventually, this will bring more bug-free and (hopefully) faster code. * Fixed major bug with joysticks, where mapping was being lost on reset, the app would crash when plugging/unplugging certain sticks, etc. * Fixed major (but rare) crash that could occur when state files were zero'ed or corrupted. * Added dialog which shows the internal joystick database (all the joysticks that Stella knows about) and the ability to remove (currently unplugged) joysticks from this database. * Added preliminary support for 'WD' (Wickstead Design) bankswitching scheme, used for a previously unreleased prototype ROM. * Improved ZIP file handling, so that it now works as a normal filesystem does (it properly shows nested files and directories). * The debugger 'reset' command now does a complete system reset, instead of simply setting the PC to the reset vector address. * The 'listdelay' command now accepts a value of zero, indicating that list-skipping (jumping to a line in a list by keypress) is disabled. * The 'ctrlcombo' command now has a GUI item, allowing it to be changed from within the application. * Added 'Shift-Alt/Shift-Cmd s' keyboard shortcut, to enable continuous snapshot mode for each frame. This is really only useful if you save snapshots in 1x mode; using it in high-resolution mode is not recommended. Special thanks to SvOlli for the idea and code. * The minimum supported version for the OSX port is now OSX 10.7. Because of this, the 32-bit version is also discontinued, as 10.7 supports 64-bit Intel only apps. * Updated internal ROM properties database to ROM-Hunter version 10 (thanks go to RomHunter for his tireless research in this area). Related to this, updated the snapshot collection. * Updated included PNG library to latest stable version. -Have fun!
