Why does a handheld have 2 analog sticks if it can't emulate ps2 games?

I'm looking at the Anbernic RG-35XX H and I'm wondering why it has 2 analog sticks.

Apparently it can emulate SNES and lighter, PS1, NDS, N64, DC, PSP, Sega Saturn and sort of some GameCube games.

What games require 2 analog sticks?
