The console is distributed in three variations, featuring the unique design of the original systems released in Japan, North America, and Europe respectively. While the North American release features an appearance based on the straight-angled grey-and-purple design of the Super NES, the Japan and PAL region releases are modelled after the rounded edge Super Famicom/PAL Super NES design as originally released in these regions.

Internally, the console uses an Allwinner R16 system on a chip with four ARM Cortex-A7 central processing units, an ARM Mali 400 MP2 graphics processing unit, and 512 MB of flash storage and 256 MB of DDR3 memory. The same hardware was used in the previous NES Classic Edition product.

The system features 720p/60 Hz HDMI display output and two controller ports; two wired SNES controllers are bundled with the system. The controller ports are hidden behind a faux front flap which is designed to appear like the original Super NES controller ports. Similarly to the predecessor’s controllers, the Super NES Classic Edition controllers have connectors that can be inserted into the Wii Remote, and be used to play Super NES games on the Wii and Wii U Virtual Console. The Wii’s Classic Controller is also compatible with the Super NES Classic Edition. While the NES Classic Edition controller is technically functional with the Super NES Classic Edition, gameplay is impractical in most games due to the absence of the X and Y face buttons and the shoulder buttons.

The console uses the Linux operating system and runs a set of emulators developed by Nintendo’s European Research & Development (NERD). These emulators provide the basic compatibility with the Super NES system, and for specific games, chipsets that were included on the cartridges, such as the Super FX chip used for Star Fox.

The Super NES Classic Edition includes two controllers with 4.5-foot (1.4 m) cables, addressing complaints about the short 2.5-foot (0.76 m) ones used for the NES Classic.
