We only use the official Raspberry Pi 5.1v 2.5a power supply and case! Hurry as this deal is only until the end of September.
Check out the link for more details. Note that we do not include the roms however we pre-configure for popular consoles so the images and meta data automatically show once you copy the rom across.
You can also upgrade to include the NESPi case + free fan (extra $32.95) which we will pre-build for you with your 16gb SNES pack - http://www.thepishop.com.au/nespi-case - Hurry limited stock in our 3rd batch!
I came here to have a bit of a sook about charging $100 for this, but for locally supplied bits, this isn't a bad price at all. You could probably get away with $60-$70 DIYing it off AliExpress, but for an out-of-the-box working product, you wouldn't do too badly to get this.
What consoles do you configure for?
