I have noticed that they changed the Ubers list but I don't know exactly how. Also that they made it so substitute no longer blocks things like sleep powder. Can someone please show me all the changes?
V2 didn't change anything; it's just that we now have "true" aka cartridge RBY as our main RBY tier instead of Stadium. The reason why this wasn't on V1 is because it wasn't programmed. Just look up "Pokemon Yellow game mechanics" and that will give you all the info you need.
