Unless you’ve been living under a rock, you’d be familiar with Nintendo’s hugely popular Classic Mini consoles. Starting with the NES, and now followed with the SNES, the consoles ship in a cute, miniature enclosure and emulate Nintendo classics using the horsepower of modern ARM chips. These consoles use an emulator that has been created especially for the purpose by Nintendo, in house – and
[Morris] [krom] wanted to see if he could take the emulator on the SNES Classic Mini and run it on the Raspberry Pi.
Yes, there are already SNES emulators on the Raspberry Pi. But anyone interested in the nuts and bolts of emulation can see the clear interest in the tricks and techniques Nintendo are using to achieve the feat. In particular, Nintendo engineers have the benefit of access to internal documentation that can make the job a lot easier, particularly when dealing with edge cases.
[krom] has been kind enough to share the full instructions necessary to recreate this feat. One stumbling block was the difference in hardware between the Raspberry Pi and the SNES Classic Mini – the Pi using a Broadcom GPU instead of the SNES’s Mali hardware. However, a workaround was simple enough – swapping out some libraries was all that was required. It also gives some interesting insight – it looks like the SNES Classic Mini relies on the SDL libraries to run.
While emulation of the SNES has been a largely solved problem for quite some time, it’s great to see more work going on in the field. In particular, the official Nintendo emulation is reported to be particularly adept at running games that rely on the SuperFX chip.
For another take on SNES emulation, try out your old Mario games on the HoloLens.
Thanks [Morris] for the tip!
