With the migration of the blog to a new provider it is now possible to offer a whole SD-card image of a complete RetroPie installation. You can find the download in the new RetroPie Downloads section of the RetroPie Project.

Why might this SD-card image be of interest for you?
Doing a manual installation with the RetroPie Setup Script is a better way for learning what actually gets installed. Also, you might already have installed something else that you do not want to re-install and configure again. Another cause for manually installing everything with the RetroPie script is that you can configure which components get installed and which not. However, if you are already familiar with the RetroPie Project, the setup script and the components it installs, or if you just would like to quickly turn your RPi into a retro console this SD-card image might definitely be useful for you!

The image was tested on an Raspberry Pi model B, revision 1 (256 MB). It is a ready-to-go installation that just needs to be filled up by your ROMs and, eventually, your BIOS files. SNESDev is also running so that controllers that are attached to the RPi, e.g., via the RetroPie GPIO Adapter, can instantly be used. SNESDev is not running, but can simply be activated with the RetroPie Setup Script so that controllers that are attached via the RetroPie GPIO Adapter can be used.

The SD-card image comes with themes for Emulation Station thanks to Xevin, Aloshi, and others around Emulation Station. I am pretty sure, though, that many people would come up with quite different design and I invite you to submit your ideas :-)

This is version 1 of the RetroPie Image and there is room for a lot of improvement! You are invited to contribute in any way, let it be themes, configuration, setup updated/comments etc. etc. !!!

You can get the image in the RetroPie Downloads section.

Update: A detailed description about the steps for creating the image was posted here.
