Historical physical/special split is ignored

[mirekdlugosz]

Before gen IV, category (physical / special) of attack was tied to its type. E.g. all Rock-type attacks were physical and all Ice-type attacks were special.

We completely ignore that. If you select e.g. Yellow, then "Hyper Beam" will be displayed as special - even though it was physical back then.

This is low priority, as we never use physical / special information anyway. It is there only to make it easier to find move that will deal more damage when used by certain Pokémon (as Pokémon have one attack stat higher than another), but in old games the same information is already contained in type.
