- Decode evolution lists from the ROM; all 251 match the pinned PRET source. - Compare CalcMonStats and CalcExpAtLevel against the original routines in the reference emulator. - Add a continuous opening playthrough from the intro to the catching tutorial, reloading a JSON save after every stage. - Port player switching in battle: the PKMN menu, forced choices after a faint, Shift mode's offer and double faints, with the original texts. - Port HP and status healing items in battle through the ROM's ItemEffects, HealingHPAmounts and StatusHealingActions tables. - Add the battle party menu and the Items pocket to the UI.
