Points to locations on the EarthBound:Map Data:Palette Animation Table.

Format

Data Pointer

• Length: 4 bytes(0x4)
• Offset within entry: 0x00
• Range of values: 0x00000000-0x00FFFFFF (long pointer)

Long pointer to the start of the compressed map palette animation data. In unmodified EarthBound, this will point into the Map Palette Animation Table.

Number of Palettes

• Length: 1 byte(0x1)
• Offset within entry: 0x04
• Range of values: 0x00-0x08

Number of palettes in the decompressed animation data. EarthBound will not attempt to decompress the animation data if this value is zero.

Also number of bytes used for the following variable-length data. Can be up to 8 or it will overfill the buffer set aside to load the data.

Unknown Variable-Length Data

• Length: varies
• Offset within entry: 0x05
• Range of values: ??

One unknown byte per palette of animation data.

Entries

There are 9 different entries, but the 9th gets used 23 times. The 9th entry is just a pointer, which seems to be pointing at the Audio block at 0x1FEE46. The other 8 entries have pointers to the Palette Animation Table, but are also followed by a line of code of different lengths. The 9th entry has 00(NULL) included after the pointer.

Entry 1(0x1FE75D to 0x1FE765)

• Length: 9 bytes(0x9)
• Offset within entry: 0x00

A note about this pointer

Rather than list the same pointer over and over, it has just been listed here once. Entries 9-31 of the EarthBound:Map Data:Palette Animation Pointer Table all point to 23 seperate entries on this table, but all 23 have the exact same 5 byte pointer to $dfec46. This pointer is unused because EarthBound will not attempt to load it when the number of palettes byte is zero.
