Apple released updates to its iMac line earlier in the week, bumping performance with the latest Sandy Bridge processors and AMD Radeon HD graphics cards. The new iMacs also sport ports -- one in the 21.5-inch models, two in the 27-inch -- for the new Thunderbolt high-speed peripheral connection interface that was introduced with the new MacBook Pros earlier in the year. Tested did a breakdown of the gaming capabilities of the new iMacs, determining that the best choice for many gamers will be to get the 21.5-inch model with a 6770M graphics card.
Apple also released the long-delayed, much-anticipated white iPhone 4 last month. If I may editorialise for a moment, the excitement over what is only a colour change is utterly ridiculous -- it almost makes me ashamed to be an Apple fan.
Arcade emulator MAME has a new project manager. After six years at the helm, Aaron Giles, a legend in the emulation scene, has stepped down to make way for Angelo Salese. Giles will still be involved as a developer on the project, however. The latest version of MAME and its OS X port, SDL MAME, is 0.142u2, which as usual offers a wealth of source changes. See here for the list. Head over to the SDL MAME website for a precompiled version, or grab the source straight from the MAME site.

Dapplegrey, a DOSBox frontend, reached a major milestone sometime recently—version 3.0. I can't kind find any release notes, but it has a shiny new UI and organisational features—along with a new icon. Mountain Lion users take note that it's not signed for Gatekeeper. You can get it from the

The Mac App Store launched in early January, pulling an impressive one million app downloads in the first 24 hours of operation. The initial lineup of 1000 apps has expanded considerably over the past few weeks. For gamers and emulation enthusiasts, the impact of the store is still unclear. It is certainly good for the exposure of games on OS X, but could potentially discourage people from looking elsewhere for software that doesn't meet Apple's stringent requirements. The only emulator that seems to have made it past Apple so far is 
Apple's stringent approval policies have come under fire recently, following the listing of an unauthorised clone of Wolfire's Lugaru HD game which severely undercut the price of the original. The developers of this unauthorised version claim to be within the rights of the GPL2 licence under which the source was released back in May, while Wolfire insists that the assets -- graphics, sound, other artwork -- are protected and may not be redistributed. At the time of writing both versions remain on the Mac App Store. Also see the 
A new(-ish) emulator called OpenEmulator -- not to be confused with Open Emu -- aims to be "an accurate, portable emulator of legacy computer systems." Development efforts are currently focused on implementing a Mac OS X interface and emulating the Apple I and MOS KIM-1 computers, although there is also functional Apple II support. The emulator notably uses a software components framework, which allows the simple addition of expansion devices and peripherals (including virtual monitors). See the
