Lower and upper HP/PP values

The lower and upper HP/PP values indicate the range of recovery for recovery-based items and the range of damage for damage-based ones. Each value uses 16 bits.

This seems to control which status ailment to heal for items such as the Antidote, Fresh Mint, etc., according to the table below:

01: Poison (Antidote)

Item animations

These bytes manage which animations get played when using an item. Byte 5E, if different from 00, will make the background darker while the item animation plays.
Byte 5F is the battle animation number.
Byte 60 is the number of the animation that plays only if the item hits the target, otherwise it won't play. This animation also prints the damage/healing numbers.

It is not fully known how byte 5F and 60 correspond to the battle animations entry table.

Item uses

If value is 01, the item will be usable only one time, in battle, before disappearing. Otherwise it won't disappear after the use.
