Game EarthBound
Start Address 0x1FE75D

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

Format

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)

Entry 2(0x1FE766 to 0x1FE76E)

Entry 3(0x1FE76F to 0x1FE779)

Entry 4(0x1FE77A to 0x1FE781)

Entry 5(0x1FE782 to 0x1FE78A)

A note about this pointer

Rather than list the same pointer over and over, I've just listed it 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 0x1FE81B. I believe some of the following data isn't actually part of the Audio block following the EarthBound:Map Data:Palette Animation Table.

0x1FEE46 to 0x1FEE52

This small area here is most likely the target of the 23 pointers. But given the way all sections of the Palette Animation Table have an FF terminator and FF interspersed in the blocks, it could be longer.

22 05 00 48 3e 48 1e 48 0e 48 2e 48 ff

0x1FEE53 to ???

This is the next location of the FF terminator, but the area could run past that.

00 04 48 00 00 4e 48 56 48 5e 48 74 48 96 48 
9f 48 a7 48 00 00 c0 48 eb 48 f6 48 2b 49 57
