Thanks for replying.

You read it right, and yes I interpreted the pointer as a little-endian reference.

I abandoned that particular investigation for now, but would still like to understand what is happening there.

ROM Hacking Discussion / My Problems with Pointers (SNES HiROM)

GAME: Slap Stick (Japan)

I'm attempting to discover the pointer tables for in-game text, and so I wrote a pointer sniffer.

Via the sniffer I found a table whose first pointer seems to be $3DC5 at offset 01C4FD.  So, I went to offset 01C53D to see what was there. To my surprise, it contained not data, but another pointer. More strangely, that pointer is... $00003DC5.

The pointer points to a pointer with an almost identical signature?  What's going on?

More info:

The table seems to be divided into two sections.  The first section is a bunch of 16-bit pointers. They point to a very similar set of what look like 32-bit pointers, and I don't know what those point to.

It takes this form:

16-bit pointers - XXXX YYYY ZZZZ WWWW UUUU

Their corresponding 32-bit entries - 0000XXXX 0100YYYY FFFFZZZZ 0200WWWW FEFFUUUU

In the 32-bit section, the first 16 bits are actual values from the ROM.  It actually follows that pattern of alternating increments from 0000 and decrements from FFFF for a little while.  Then, those bytes switch to a format that isn't as simple to discern.
