# Prebuilt Image

Alternatively, you can use this VirtualBox image:
[http://www.rust-class.org/static/cs4414-ubuntu-12.04.2-32bit-vdi-ps4-env.zip](http://www.rust-class.org/static/cs4414-ubuntu-12.04.2-32bit-vdi-ps4-env.zip).
This includes all the tools you need for ps4, but may take a few hours
to download.  (Note that standard unzip may not be able to unzip this
file.  On Mac OS X, [Keka](http://www.kekaosx.com/en/) works.)
