Editing BIN textdata (section)

== Item / NPC / monster records — <code>NN.dat</code> ==

The numbered <code>textdata/[[textdata NN.dat|NN.dat]]</code> files are the game's object definitions — weapons, armor, and every other item, plus NPCs and monsters. Despite the <code>.dat</code> extension they're plain text: line 1 is the record count, then each record is 3 lines (Korean name, English name, a space-separated stat line). There are 14 record types, each with its own fixed stat-line column count:

{| class="wikitable"
! Type !! Category !! <code>.dat</code> files !! Stat columns !! Notes
|-
| 0 || [[Weapons]] (katana/sword/axe/spear/bow/bowgun) || 16–22, 62, 63 || 44 || 6 equip stats + weapon params + ~14 sprite/animation ids for the swing/effect frames
|-
| 1 || [[Armor]] || 23–31, 61 || 16 || 6 equip stats + sprite/variant
|-
| 2 || [[Rings]] || 8, 32 || 14 || 6 equip stats only
|-
| 3 || [[Emblems]] || 9, 33 || 8 || header only (no stats/price)
|-
| 4 || Medicine / food || 10, 11, 34 || 10–11 || header + recovery amount + effect-name string
|-
| 5 || Money || 15 || 8 || header only (it ''is'' currency)
|-
| 6 || [[Scrolls]] || 38–43 || 33 || header + skill/effect params
|-
| 7 || [[Books]] || 44–47 || 8 || header only
|-
| 8 || Misc items (ore / monster-item / letter) || 35–37, 48, 49 || 8 || header only
|-
| 9 || [[Monsters]] || 64–69, 73, 78, 79 || 32 || HP/stat/AI/drop block (server-side)
|-
| 0xA || Monsters (special) || 70 || 36 || extended monster block
|-
| 0xB || NPCs (field/party) || 5, 74, 75 || 8 || header + reference fields, no shop
|-
| 0xC || NPC shopkeepers (incl. Au) || 77 || 22 || header + shop-type code + 14 per-category "sells this" flags
|-
| 0xD || [[Monsters]] || 89–92 || ~3 || sparse / mostly empty
|}

Every record starts with the same header: dat file number, record index, then (for items) sub-type/grade, an item-level/sort key, an icon bitmap index, and buy/sell price. Equippable items (weapon/armor/ring) then carry a confirmed, fixed 6-stat block — '''OFC''' (offense), '''DEF''', '''AGL''', '''LUCK''', '''LIFE''', '''FOOD''' — used both for the item-detail panel and (server-side) as the equip bonuses applied to a wearer's totals. See [[textdata NN.dat]] for the full field-by-field breakdown.

Each <code>NN.dat</code> that has flavor text has a matching '''<code>[[textdata cptNN.txt|cptNN.txt]]</code>''' — a <code>Korean~English</code> description file with the same <code>/e</code>/<code>/n</code> markers, paired by file number (line index = record index). Not every <code>.dat</code> has one (e.g. 9, 15, 22, 31–33, 38–43, 61–63, 76 are data-only).
