UCC food recipe slots

extracted/nds/data/ucc/names.ofs is a RESO container, variant=1, with 192 slots totalling 11,376 bytes. Most slots are simple 68-byte name records; 10 slots are "multi-name" arrays of 68-byte sub-records.

Simple slot (68 bytes)

Multi-name slot layout

Multi-name slot length is always a multiple of 68 bytes. Sub-record [0] is the category/base name; sub-records [1..N-1] are recipe variants keyed by the 2-byte ingredient-pair code at +0x00. The engine selects a variant by matching the player's ingredient pair against each sub-record's key.

Multi-name slot inventory

Total sub-records: 49 (10 base + 39 variants), 3,332 bytes.

Worked example — Slot 57 (Cake)

[0] hdr=05000000  name='ケーキ'           (category root; simple-slot-style header 0x0005)
[1] hdr=55550000  name='ショートケーキ'   (variant; key = ASCII 'UU' / 0x55,0x55)

Worked example — Slot 65 (Cream Stew, alphabet {3,7,8,9})

[0] hdr=05060000  name='シチュー'           (root)
[1] hdr=37390000  name='クリームシチュー'   key '79'  (= 0x37,0x39)
[2] hdr=39370000  name='クリームシチュー'   key '97'
[3] hdr=37380000  name='クリームシチュー'   key '78'
[4] hdr=38370000  name='クリームシチュー'   key '87'
[5] hdr=38390000  name='クリームシチュー'   key '89'
[6] hdr=39380000  name='クリームシチュー'   key '98'
[7] hdr=33370000  name='クリームシチュー'   key '37'
[8] hdr=33390000  name='クリームシチュー'   key '39'
[9] hdr=33380000  name='クリームシチュー'   key '38'

All 9 variant names are identical JP text; only the 2-byte key differs. The 9 keys cover the non-equal ordered pairs over alphabet {3,7,8,9} where at least one digit is from {3} plus a partner in {7,8,9}, or any ordered pair of distinct digits in {7,8,9}.

Re-emit constraint

The RESO container is reflowed on rebuild — per-slot length is recomputed from actual payload. However, within a multi-name slot the engine indexes sub-records at fixed 68-byte strides. Therefore:

• Every sub-record must remain exactly 68 bytes.
• Bytes +0x00..+0x03 (the recipe-pair key) must be preserved byte-for-byte.
• EN name fits in 60 bytes (30 UTF-16 code units, then NUL).
• Sub-record count per slot must stay at N (each variant key must keep its slot).
