Game Developers using Visual Studio are able to create games that can be made cross compatible between Windows (Microsoft) Operating Systems, including Windows Phone 7 and the Xbox 360. 90% of the generated code is the same between the various target platforms, leaving about 10% for platform specific stuff. Perhaps one could look at it as some sort of SDL-layer?

In this article, Microsoft demos a cross-platform game that can be run on a computer with Windows 7, a mobile phone 7, and the Xbox 360 console. A video shows how a Microsoft employee starts the game on one device, continues it and finishes it on others. The progress made within the game is automatically transferred from one platform to the other - probably by use of the Windows Live platform.

Windows Phone 7 development is mostly done with Silverlight and XNA.

Cross platform gaming between PC and Xbox 360 was possible before, just take a look at the game Shadowrun.

In the interest of sharing, I'd like to provide my current list of working emulator sites for various platforms. All of these enable gameplay directly within your browser, so there's no sticky business of downloading software and finding the necessary game files to get it all going. These are all great sites and we should all show our support. I'm dubbing this the "November 2009" edition of the list and would love to keep adding to it, so suggest away and when I do the next edition, I'll expand it. Here goes:

Leonie Manshanden - marketing director at Midway - has announced they will be producing the classic adventure game Myst for the popular dual screen portable console by Nintendo. Now this is a favorite of mine. I wonder if the other 'episodes' will also become available.

John Carmack - one of the Id software founders - has shown interest into the possibility to create a special Quake-Arena version for the Nintendo DS. He was inspired by playing Metroid Prime Hunters - which is quite a good fps on the Nintendo DS btw! - read more.

As you know, running a site such as Armchair Arcade takes money, and, while we'd still do this even if the Website didn't generate a penny to help offset our hosting and bandwidth costs, it's nice when something we offer does work. This brings me to our affiliate program with PlayFirst, publishers of fine small form games for platforms like the PC, Macintosh and Web. That's been by far the biggest hit of our modest efforts and we just wanted to take a moment to thank all the AA'ers who took the time to click on the links, play some of the games offered and make purchases of their favorites. It's very much appreciated! For those who haven't checked it out yet, click on over to PlayFirst with the following links:
