Great question, I'd guess emulating it is within the capabilities of the device. (I don't know much about the Spectrum but just a guess based on age). Would those games work well on a controller?
The RG351 is really just an ARM Linux box inside a Gameboy shaped case, so it can really do pretty much whatever within the limits of its hardware. It's a really neat little device, I've been having lots of fun with mine. I've played mostly SNES and Gameboy stuff on it (that's where my nostalgia lies), but I've run a few PSP games on it with decent to middling results.
