(no containers/strings -- pure code)

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.

Overlay ID 94

File ID 94

RAM load address 0x0215c540

RAM size 6,208 bytes (0x1840)

BSS size 0 bytes

On-disk compressed size 5,108 bytes

Compression flag 0x1 (BLZ-compressed)

Functions 37

External calls 38

Jump tables 4

Data items 115

Code coverage 64% (3,968 of 6,208 bytes)

Reading the binary

The overlay ships on the cart at file ID 94 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 + 94 * 0x20, allocates the destination RAM region at 0x0215c540, decompresses the body in-place (if compressed), and resolves any external relocations.

To inspect this overlay outside the running game, decompress overlay/overlay_094.bin with ndspy.codeCompression.decompress() (Python ndspy library) and load the resulting plaintext into Ghidra or IDA at base address 0x0215c540. The raw Ghidra auto-analysis dump used to populate this page lives at notes/overlay_knowledgebase/raw/ov094.json; the per-overlay descriptive markdown is at notes/overlay_knowledgebase/ov094.md.

Embedded strings

No UTF-16 LE strings are embedded directly in this overlay's binary. Any text it displays at runtime comes from a container file loaded via the content cache.

Container references

This overlay references no container files — it is pure code (or reads only from globals shared with the persistent ARM9 binary).

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 37 functions covering 3968 of 6208 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

No major conflicts detected with prior-pass `overlay_role_final.json` record.
