Yes it does.
There is currently a bunch of new research not yet implemented, regarding encounter slots and nature checks like method J and method K (legality).
Ruby and Sapphire on an emu have an initial seed 5A0, Emerald is 0, FRLG have a timer0 related one and is not really controllable on GBA (you gotta emu).
Ruby and Sapphire RNG is pretty underground, there's no dedicated Research Topic like Emerald/FRLG has.
I'd wait a few weeks, Reporter has to be updated!
