Windows games developers now have an easy way to bring their games to the Mac, thanks to a new software technology called Cider.

Developed by TransGaming Inc, Cider is a Mac portability engine. It allows Windows game developers to extend their titles to the platform with little or no coding.

Cider allows Windows games to be run on Intel Macs without any modifications to the original game source code. It works by directly loading a Windows program into memory on an Intel-Mac and linking it to an optimised version of the Win32 APIs.  Games are simply wrapped up in the Cider engine and they work on the Mac. 

Games migrated to the Intel Mac using Cider will also run on Linux under TransGaming's Cedega engine.

The news means developers in future may only have to maintain one code base while still serving multiple platforms. Cider-powered games use the same copy protection, lobbies, game matching and connectivity as the original.  The solution is targeted at game developers and publishers. It is not an end user product. 

Explaining the need for the solution, TransGaming pointed out recent analyst predictions that estimate Apple will triple its share of the home computer market.

"With only a small collection of games available, the Mac gaming market is a void waiting to be filled," the company said.
