Picking Out the Best Raspberry Pi for Emulation

The Raspberry Pi may not be the only single-board computer (SBC) on the market, but it's easily the most popular development board available. Because of its widespread use, tons of Raspberry Pi projects are possible. For beginners, a basic Linux desktop or lightweight home theatre PC (HTPC) proves an easy yet rewarding endeavor. An easy, enjoyable Raspberry Pi experiment is a Raspberry Pi retro gaming arcade. Find out about the best Raspberry Pi for emulation, from the best Raspberry Pi emulator setup and operating systems (OSes), to an emulation build!

What is the Raspberry Pi?

The Raspberry Pi is a maker board that, as a mini computer, comes with all hardware baked in. Onboard, you'll find a CPU, GPU, RAM, and every component necessary for computer, just add an operating system and boot medium. While the Raspberry Pi 3 remains the flagship Raspberry Pi board, there are several different iterations of the Pi. The most affordable version of the Pi is the Raspberry Pi Zero. It's engineered for Internet of Things (IoT) projects such as a solar-powered house, pocket projector, or smart home tech. Likewise, the Raspberry Pi Zero W arrives as an IoT-oriented Raspberry Pi board, but with added wireless networking capabilities. 

The Raspberry Pi 3 A+ steps up processing power and connectivity at the expense of a larger footprint. The Raspberry Pi 3 B+ boasts the most RAM of any Raspberry Pi board at 1GB, and features the same processor as its Raspberry Pi 3 A+ counterpart. Both the B+ and A+ tout enhanced networking capabilities, with both Wi-fi upload and download speeds clocking in about the same. Benchmarks from the likes of sysbench provided data showing both boards to be roughly even. There's not a ton of difference, except when RAM comes into play. For Linux desktops, the Raspberry Pi 3 B+ is a better choice. Moreover, the Raspberry Pi 3 A+ lacks an Ethernet port, so for those demanding a hardwired Internet connection, check out the Pi 3 A+.

What's the Best Raspberry Pi for Emulation?

While it may seem the best Raspberry Pi for emulator use is the Raspberry Pi 3 B+, that's not necessarily correct. Rather, the Raspberry Pi 3  A+ runs retro gaming operating systems such as Lakka, Recalbox, or RetroPie equally well when compared to the Raspberry Pi 3 B+. Because Raspberry Pi emulation doesn't demand much RAM, and it mostly CPU and GPU bound, the A+ handles even many Nintendo 64 games phenomenally. Some PlayStation Portable ROMs function properly too, although PSP, Dreamcast, and N64 performance is variable.

Best Raspberry Pi Emulator Build: Other Considerations

Aside from hardware and software, you'll likely want to use a case. Retro gaming cases such as Nintendo Entertainment System (NES), Super Nintendo Entertainment System (SNES), and Sega MegaDrive cases lend an old school flair which jazzes up a Raspberry Pi emulation build. Unfortunately, most of these only fit the Raspberry Pi 3. There are also kits like the Pimoroni Picade

Connectivity comes into play. The Raspberry Pi 3 A+ lacks Ethernet. While emulation doesn't necessarily require an active Internet connection, you'll probably want Internet connectivity for scraping ROMs, and maybe streaming video or games. Since both boards utilize the same Wi-Fi connection, that should be fine. But if you need Ethernet, opt for the Pi 3 B+. 

Moreover, you may wish to hook up USB controllers. The Pi 3 B+ includes four USB ports to the Pi 3 A+'s one. Sure, you can snag a USB hub, but the B+ is a better buy. Although, if you don't want to play anything more demanding than SNES and Sega Master System titles, the Pi Zero should be fine and fits in a small, portable form factor. 

Winner: Raspberry Pi 3 B+

Best Raspberry Pi Emulator OS

However, there's more than pure performance which factors into selecting the best Raspberry Pi emulator setup. You'll want to select the best Raspberry Pi emulator OS. For that, I'd recommend either RetroPie or Lakka. However, RetroPie, Recalbox, and Batocera tout a similar set of features. These boast what's arguably the best Raspberry Pi emulator frontend in EmulationStation. Plus, RetroPie, Batocera, and Recalbox include the ultra-powerful Kodi media centre for HTPC purposes. Batocera and Recalbox are virtually the same, whereas RetroPie, while similar, benefits from a slightly larger community, additional emulators, and a plethora of resources such as shaders. 

For most users, RetroPie is the best choice. Beginners may appreciate the simplicity of Recalbox or Batocera which are pretty plug-and-play. What these lack in complexity, they compensate for in ease of use. But many options such as shaders aren't available. Lakka is a robust choice, and balances out-of-the-box controller functionality with an overwhelming number of configuration options. Overall, I prefer RetroPie, though Lakka is an excellent choice that just works. 

The Best Raspberry Pi for Emulation: Final Thoughts

With a smorgasbord of hardware choices, the Raspberry Pi 3 B+ comes in as the best Raspberry Pi for emulation needs. Because it's the most powerful, features Ethernet, fits in retro gaming cases, and touts four USB ports. As such, it's the premiere emulation Pi board. However, for a Raspberry Pi emulator handheld console, the A+ or Pi Zero work well.

Alternatively, the Odroid Go and Clockwork Pi arrive as excellent DIY handheld gaming devices. The ASUS Tinker Board is a solid alternative which fits in Pi cases and runs RetroPie and Slash TV for gaming and HTPC purposes. Or, the Odroid XU4 features an N64 shell for a do-it-yourself N64 classic mini. Likewise, the Pine64 RockPro64 runs Recalbox for a beefy retro gaming console.
