*Some tables have unknown data bytes at the beginning/end, its possible these tables are offset from there true position.
*Many tables have an empty entry at the beginning for 'None'. Not all tables have this taken into account yet. If a table has an odd number of entries, this is likely the case.
==Prizes/Random Treasures Table==
*Data starts at 0x0061D8A0 and ends at 0x0061D99F in the ROM.
*There are 256 entries, 1 bytes in length each.
*The first 108 bytes are random treasures (picked up when moving onto a map square).
**Divided into 3 groups. Higher groups have better treasures.
**The groups contain 10,13, and 13 entries respectively.(This needs to be confirmed)
**When an item is picked up, a random entry is selected.
**Each entry has 3 items, one for each of low, medium and high biorythm.
*Next are Quest rewards, starting at 0x0061D90C
**Divided into 10 groups of 8 items each
**Lower groups are better. Group is improved by beating harder quests, faster.
**Items are randomly selected among the group
*Next are VS. Mode rewards, starting at 0x0061D94C
**64 Items total
**Unknown how this functions.
==Hire Shop Data Structure==
*Data starts at 0x00622494 and ends at 0x006224E3 in the ROM.
*There are 10 entries, 8 bytes in length each.
*It's unknown how the game decides which entry to use. (e.g. Mermaids only in Rana, Giants only later in the game, random class every time, etc...)
*There is no termination data at the end of the table. The length must be hardcoded somewhere else.
