The RNS V2.25 is powered by a Raspberry Pi 3 B+ overclocked to 1500Mhz with at 5v cooling fan, along with a 32GB Micro SD for storage (Anything from 8GB or more for storage will work as well)
WARNING: OVERCLOCKING YOUR PI CAN DESTROY IT AND VOID ANY WARRANTY, DO SO AT YOUR OWN RISK! IF YOU DO, ACTIVE COOLING IS A MUST!
The OS is Retropie 4.4. (Retropie is built upon Raspian Stretch Lite)
This design is much simpler than the previous model, with better heat ventilation and much shorter printing times. The large front vents across the top were an inspiration from the Atari 2600 with it's horizontal ribs across the top.
Changes from the previous design include: The heat ventilation locations have changed, along with them being elongated and widened. The console's base stand has been removed due to the previous model tipping over easily. Now the PCB mounting plate is also the base. Without the previous base stand, the HDMI and power supply are easier to plug in.
You will need a Bluetooth or USB connected controller, along with a Keyboard and Mouse to use Retropie.
(As of December 2018, Retropie has an experimental package to stream Steam games like the Steam Link)
