Boxer 1.1 added support for Mac OS X 10.7 Lion, and Boxer 1.1.1 improves upon that. For those who use joysticks, this is an update you will definitely want, as there was a lot of work done with joystick controls and input.

Joystick improvements:
* Better controller mappings for:
— Logitech Dual Action, RumblePad 2, and Fx10 series gamepads
— Logitech Formula Force, MOMO Racing and G25/G27 series wheels
— 3rd-party XBOX 360 controllers
* CH Flightstick Pro throttle emulation works better with gamepads and displays the current throttle level on-screen.
* Per-game option to disable joystick emulation, to avoid interfering with external tools like Gamepad Companion.
* If a game seems to be ignoring your joystick input, Boxer will remind you to turn on joystick control within the game.
* Reduced axis deadzone from 25% to 20% to make sticks more sensitive.
* On most controllers, buttons 5-8 are now also bound to the four DOS joystick buttons.
* Improved gamepad detection to more reliably apply twin-stick racing wheel layout.

Better disk handling:
* The program panel now discovers programs located on ISOs and floppy-disk images, and can set them as the default program for a gamebox. This makes it much easier to play games that have left all their programs on the CD.
* Drives are scanned for available programs in the background, resulting in quicker gamebox startup.
* Added support for .IMG and .VFD floppy-disk image formats.
* Fixed floppy-disk images hanging on PowerPC Macs.

Fixes for 10.7 Lion:
* Fixed nasty fullscreen lag under Lion.
* Fixed occasional Lion crash when tapping the DOS window’s close button on a trackpad.
* Disabled restore-windows-at-startup in Lion, to prevent numerous startup bugs and general misbehaviour.

General fixes and tweaks:
* New bezel notifications for switching to fullscreen, pausing, adjusting CPU speed and adding/removing drives.
* Flicker-free fullscreen transitions, smooth crossfades in program panel, and other cosmetic improvements.
* Automatic configuration for Pinball Dreams, Pinball Fantasies and Metaltech: Earthsiege.
* Disabled blur effect behind Inspector panel in preparation for App Store compatibility.
* Removed Growl support, now that it has been superseded by built-in bezels.

Requires: Mac OS X 10.5 and newer

If you are still on an older version of Mac OS X, namely Mac OS X 10.4, check the link below for details on older version of Boxer to run on your Mac.

Quoting Marcus:

Unfortunately the official 0.70 build of DOSBox for OSX has all kind of compiler switches set to juice the most performance out of your PowerPC G4 (and up) CPU and obviously doesn’t run on old G3 anymore. For those people I provide a precompiled DOSBox binary here.

Macosxhints.com listed it as their Pick of the Week for August 28, and the reviewer mentions what most people use it for: DOSBox isn’t rich on user interface features, but it works quite well. There’s even SoundBlaster support, so you get in-game sound. I’m sure DOSBox could be used for more productive tasks as well, but it’s great as a flashback gaming machine!

Cocoon Wrapper for DOSBox is exactly what it sounds like – a wrapper for DOSBox, which is an emulated DOS environment (most people use it to play old DOS-based games).
