• Range of values: 0-8 (0x0-0x8)

00: Clear
01: Sunny

• Length: 2 bytes
• Offset within entry: 0x07-0x08
• Range of values: Currentely Unknown

This value regulates additional layout details like the dead-ends, the water/magma/sky tiles, and trasure rooms.

Item Density

• Offset within entry: 0x16
• Range of values: 0-255 (0x00-0xFF)

Floor Number?

• Length: 1 byte
• Offset within entry: 0x17
• Range of values: Currentely Unknown

Seems to indicate the floor number, tough modifying it don't seem to affect anything.

Event Floor

• Length: 1 byte
• Offset within entry: 0x18
• Range of values:

If different from zero, sets a prefabricated floor layout and/or shows a cutscene. Note that many cutscenes require specific animations that only few pokémon have implemented. To avoid game crashing, the appropriate pokémon must be present in the pokémon list set by the relative Floor Data ID Table entry.

Visibility

• Length: 1 byte
• Offset within entry: 0x22
• Range of values: 0-2

Sets the range of visibility for the floor, making the player unable to see on the screen enemy Pokémon present outside the set range. This also limits the range of room-ranged moves when used outside rooms.

00: Full visibility
01: 1-tile visibility outside rooms, can't see outside room
02: 2-tiles visibility outside rooms, can't see outside room

Max POKé Found

• Length: 1 byte
• Offset within entry: 0x23
• Range of values: 0-38 (0x00-0x26)

This regulates the max value of every pile of money found on the floor.

When the game generates a pile of POKé to be placed on the floor, it draws a random value from 1 to 100, which points to one of the 100 values below. If the value drawed is greater than the max POKé value multiplied by 40, it will halve the value ID (rounding up) and check again if it is greater, and repeating this until it gets a value smaller than the set maximum.

Note that due to how the amout is calculated, it is useless to use values greater than 38 (0x26).

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?
