Port the PC and boxes

Read TileCollisionStdScripts from the ROM so the Pokémon Center PC runs
PokemonCenterPC: Bill's PC (deposit, withdraw, release, change and name
boxes), the player's item storage (withdraw, deposit, toss, mail box) and
Oak's Pokédex rating. The house PC now opens the full player's PC menu.

A catch with a full party goes to the current box through SendMonIntoBox;
a full box keeps the ball, and filling it queues Bill's call as a memory
script after the battle. Saves gain boxes, box names and PC items,
migrated by absence.
