Please realize that games are available through a community technical preview
of XNA Game Studio 3.0.
I suggest waiting until later this year when the process is streamlined for non-technical users if you do not understand what you are doing after reading the instructions on how to do so.
However, if you absolutely must, the following are my instructions for installing games on your Zune device:First make sure of the following:
A. You are using either Windows Vista 32-bit (x86) or Windows XP 32-bit (x86). x64 is not currently supported in this technical preview.
B. You have uninstalled any Windows Live Redistributables.If you meet the above conditions then you can continue with these steps:
1. Install Visual C# 2008 Express Edition using the Web Install here: http://www.microsoft.com/express/download/
(The green block)
2. After you have that installed the above in full, download and run XNA Game Studio 3.0 CTP from here: http://www.microsoft.com/downloads/details.aspx?FamilyId=DF4AF56A-58A7-474C-BFD0-7CF8ED3036A3&displaylang=en
3. Download the code for the game or application you'd like to deploy to your Zune device. Here's a working link to the list of Games and Applications that have been developed thus far for Zune: http://zunerama.com/forum/index.php?topic=9811.0
4. Next, plug in your Zune device via USB sync cable and close Zune software if it starts up.
5. Start up Visual C#. Under the Tools menu, select 'Add a new device' and choose the appropriate options for your Zune. Make sure your Zune displays XNA Connect on it after you do this to ensure it is connected properly.
6. Under the File menu choose 'Open Project' and then navigate to where you extracted the .zip files and open that up until you see a <filename>.sln file; this is the file you choose to open.
7. Under the Build menu, choose 'Deploy <app/game>' where <app/game> is the name of the game or application you downloaded in step 3. This will deploy the code to your Zune. Wait until Visual Studio reports success in the output window and your Zune goes back to displaying 'Connected'. At this point you may now disconnect your Zune and launch the game/application in the newly added 'games' option from your Zune menu below 'podcasts' and above 'settings'.List of Games and Applications Thread Link:http://zunerama.com/forum/index.php?topic=9811.0
