Aleph One, the open-source continuation of Bungie's Marathon 2 engine, has reached its 1.0 milestone after 12 years in development. For those unfamiliar with the project, Aleph One allows all three games in the Marathon trilogy (which are now freeware) to be played on modern systems, with OpenGL shader support, mouse-look, gamepad support, mod support, and Internet co-op and multiplayer. The new version fixes lots of bugs, offers a plethora of Lua updates, adds HD graphics to Marathon 2, and more. Get it, and the Marathon games, from the Aleph One homepage.

The current version, 0.0.8, supports emulation of the 8086 processor, the infrared keyboard and mouse, the screen, floppy drives, up to two hard drives (why are they called Winchester disks?), and the support chipset. Be warned, however, that it is very early in development, and may not work well -- if at all. You can download the source from the 
Previous brings NeXT computer emulation to the Mac, with the 0.3 version released in late January. This update brings partial read compatibility to SCSI disks, but apparently breaks the MMU emulation. Head over to the 
Commodore 64 emulator micro64 has been updated to version 1.00.2012.01.13 Build 665.
