| Last Played
| 4
| A big-endian 32 bit unix timestamp indicating when the level was last saved, will overflow and become negative at '''03:14:08 UTC on 19 January 2038''' due to [[Minecraft:wikipedia:Year 2038 problem|the year 2038 problem]] and will overflow every ~136 years after that.

|-
| World Name

| 4
| A little-endian 32 bit float
|-
| Pitch
| 4
| A little-endian 32 bit float, an error in the code causes this value to be read incorrectly
|-
| Yaw
| 4
| A little-endian 32 bit float representing the player's yaw in degrees
|-
| Unknown
| 4
| A little-endian 32 bit float
|-
| Fire
| 2
| A little-endian signed short representing the number of ticks until the fire is put out. Negative values reflect how long the player can stand in fire before burning. Default value: -20
|-
| Air

| Hotbar
| 36
| 9 slots that take up 4 bytes each, the first two bytes is the item ID<ref group="note">Every items from Pocket Edition [[Minecraft:Pocket Edition v0.1.0 alpha|0.1.0]] to [[Minecraft:Pocket Edition v0.1.3 alpha|0.1.3]] has an ID only takes up 1 byte with the exception of [[Minecraft:Camera]], which takes 2 bytes (c8 01).</ref>. The other two bytes have unknown use and are always 0x00. The last slot is always saved as 0xFF for every byte, it's known to be a hotbar slot as the <code>minecraftpe</code> library loops through 9 hotbar slots.
