Why do bootleg consoles only run NES games?

After watching all of these bootleg videos on youtube and having owned a bootleg "game prince" once before, I am starting to ask myself. Why do these consoles just have NES titles? I get these are Chinese imports but wouldn't an original gameboy or atari be easier to emulate?

It's just cheap to run and there are a lot of NES bootlegs floating around the internet, probably more than any other console. The goal of bootleggers is to sell a good looking product with a cheaper than normal price using the cheapest materials possible and the least effort possible to make a sizeable profit so it makes sense to emulate NES games because hardware for emulating them is only a couple cents.
As for why they don't use Atari or Gameboy games I think they use NES games because they have more content than gameboy and atari games. NES games are about as basic you can go while still having a good gaming experience imo.

Because you can just put a NES-on-a-chip into some plastic and lo, behold, you've a console. There's no emulation involved.

Oh alright! That makes a lot more sense.
