Rollback netcode: more complicated to port than Witcher 3. 

in relation to SamSho on switch not having rollback, the CPU can't handle it quick enough depending on the game itself. 

To rewind in emulation, you need to go back several frames and simulate forward. Each simulation needs to happen fast enough so that you don't affect framerate. Those simulations on Switch's processor take way longer than any other platform.

That doesn't make any sense. A fighting game, especially a 2D one, doesn't have overly complicated physics, and rollback is about split seconds, so easily doable.

Now the tweet talks about an *emulated* game. In this non-native case the whole emulation has to be done, including the (in case of rollback) pointless rendering. That is much more work needed.
