Two PIs Are Better Than One! Dual Boot XBMC/Kodi + Emulation Station

My ongoing quest to get the most out of the humble raspberry pi led me to two main uses: media playback and emulated gaming. The pi is powerful enough for both and can handle a huge variety of formats and emulated platforms, but can it do both on one install? Not exactly, but thanks to a great tool called BerryBoot you can 'dual-boot' into two different pi operating systems as and when you need them.
