Header

Numeric metadata for this overlay as read from the overlay table at ROM offset 0x8DE00 (per-entry stride 32 bytes). Function counts, data-item counts, and the call-graph fan-out are from a Ghidra 11.3.1 headless auto-analysis pass.

Reading the binary

The overlay ships on the cart at file ID 60 under the BLZ code-LZ compression wrapper (the same backward-LZ scheme Nintendo uses for executable ARM9 code). At load time the engine reads the overlay table entry at ROM offset 0x8DE00 + 60 * 0x20, allocates the destination RAM region at 0x02155a00, decompresses the body in-place (if compressed), and resolves any external relocations.

To inspect this overlay outside the running game, decompress overlay/overlay_060.bin with ndspy.codeCompression.decompress() (Python ndspy library) and load the resulting plaintext into Ghidra or IDA at base address 0x02155a00. The raw Ghidra auto-analysis dump used to populate this page lives at notes/overlay_knowledgebase/raw/ov060.json; the per-overlay descriptive markdown is at notes/overlay_knowledgebase/ov060.md.

Embedded strings

9 UTF-16 LE strings live inside this overlay's compiled binary. These addresses are absolute (inside the overlay's RAM image after load). The text is stored as little-endian UTF-16 code units, NUL-terminated.

0x0215645f `蒐怠ぃ刘`

0x0215673e `适ゟ适頃`

0x02157446 `逄ゟ逄順`

0x021577d2 `ヿ利頂崩゠适`

0x0215831c `唨頂ょ适`

0x02158cd0 `逈頒鄍メ`

0x02158d0a `嶁逎頋唁頒メ`

0x02158dce `ご瀁預崀`

0x0215940c `ヰ飿梐胈棇胝`

Container references

Distinct container basenames referenced by this overlay. Each is loaded via the content cache by passing the basename string to a lookup that resolves it to a file ID in the ROM's FAT. The path column shows the file's location in the clean extract, where resolved.

warehouse → data/2d/warehouse.lzs

Unresolved

These container basenames appeared in the overlay's string table but no file of that name was found in the clean extract. Most are false-positive ASCII matches (function names, register maps, fragments of other strings); a few may be containers that the overlay names but never actually opens. Listed for completeness.

2d/itemstackwnd.lzs — no matching container found in clean extract
2d/warehouse.lzs — no matching container found in clean extract

Function list

Functions Ghidra auto-identified inside this overlay's RAM range. Names prefixed FUN_ are auto-generated from the function's entry address; size is in bytes; the "calls" column counts both intra-overlay branches and external ARM9 call targets. The "strings" column counts how many UTF-16 LE strings each function references.

Open questions & conflicts

Open questions / unknowns

Auto-analysis identified 57 functions covering 13272 of 15584 overlay bytes.
Function names are auto-generated `FUN_<addr>`. Manual renaming based on call-graph + string-ref analysis is a follow-up.
BSS size is 0 bytes; Ghidra-imported overlay does not include BSS so any references into the BSS range appear as unresolved.

Conflicts with the prior shallow pass

Partial overlap: prior-pass had `['itemstackwnd', 'warehouse']`; Ghidra adds `['2d/itemstackwnd.lzs', '2d/warehouse.lzs']`.
