After a year of frequent incremental updates (around 2500), Nintendo Wii and Gamecube emulator Dolphin has been bumped up to version 3.0. If you haven't been paying attention since the 2.0 release, Dolphin has ditched the plugin interface in favour of a integrated architecture, in addition to reaching near-perfect audio emulation and much improved levels of performance and accuracy. See the Release Announcement for a more detailed rundown of the changes. You can get a pre-compiled build of version 3.0, as well as the more recent source changes, from the Dolphin download page.

Apple has released new MacBook Pros, with the new Sandy Bridge processors and Thunderbolt connectivity. Early reports indicate that they are much faster than the previous generation machines -- to the point where the new baseline 13" model matches or betters the old 17" model on many speed and performance tests.

It has been revealed that Mac OS X Lion will drop Rosetta, a software abstraction layer which provides support for PowerPC binaries on Intel machines. This is an interesting move that some are labelling premature, as, on the one hand, it forces developers to get their code up to modern standards, but, on the other, it breaks compatibility with some professional software still actively in use. Some of the other features slated for Lion are looking promising, though.

At a media event on Wednesday, Apple announced a second-generation iPad, complete with a processor upgrade (the iPad 2 sports a 1GHz dual-core A5 processor), front- and rear-facing cameras, Smart Covers, and an option to get it in white colour. The new iPad models will be available in the US from March 11, and in other countries over the following weeks. In the meantime, you can pick up the first-generation iPad at a discount.

Also announced at the event was iOS 4.3, which features some useful enhancements to AirPlay, allows iTunes Home Sharing, improves performance in Safari, and offers the long-demanded iPad side-switch preference (rotation lock or mute). It will be available from March 11, and is compatible with iPhone 3GS, iPhone 4 GSM, 3rd-gen iPod Touch, 4th-gen iPod Touch, iPad, and iPad 2 (I guess that means iPhone 3 and 2nd-gen iPod Touch owners should upgrade now).

We've had a quiet month in Mac emulation news, but there were notable updates to VICE, Dapplegrey, and gbpablog, amongst others. Hit the jump for details on these and other minor emulator updates, as well as a couple of Mac gaming tidbits.

Highlights in Apple news this past month include the announcement that the Mac App Store will open on January 6 and the passing of a new milestone in market capitalisation. Apple’s market cap now stands at over $300 billion, which is still some $70 billion behind Exxon Mobil -- the largest US company. This marks a great year in stock for the company, which passed $200 billion back in March and rose to become the second biggest US company in May (leapfrogging Microsoft).

Open-source x86 and AMD64/Intel64 virtualisation tool VirtualBox received a major update shortly before Christmas. Version 4.0 provides a major reworking of the GUI, adds support for new virtual hardware, removes the 1.5/2 GB guest RAM limitation on 32-bit hosts, and more. See the changelog for a full run-down and the official site for a download.

In news we missed last month, MS-DOS emulator Boxer has entered public beta for version 1.0. New builds were released throughout December, with the biggest changes being that games can be imported “painlessly” from CDs or folders, there is a dedicated games folder automatically created, and the program launches with a welcome panel. Check out the official Boxer website for more details.

MAME and SDLMAME were updated three times over the past month. The latest version (0.141) adds support for the games Heavy Unit, Poizone, Silver Game, and Jack Potten’s Poker, in addition to providing a long list of improvements and bug fixes. Check out the MAME website for full details, and grab the latest SDLMAME build from here.

More updates after the break.
