Choose core about lemuroid

I think this is something that we should consider. Adding every core Libretro supports might be very scary for the user, but allowing very few alternative cores might prove beneficial. MelonDS is a great example.

From what I've seen so far, all the cores you use are the ones I've always used (I still don't use NES so I don't know which one I use) but the only core I'm missing is MelonDS. For example in NES I use Nestopia, but I know that many like FCEUX Then it would be good if there are the most popular options. Although there are few devices with more than one core that stands out.
