DM Nexus — Extracted File Classification
137 files present in the Sega Saturn ISO directory (Track 1, MODE1/2352). Volume: DUNGEONMASTERNEXUS. Product: T-9111G V1.003 (1998-02-03).
The local user-supplied corpus contains 131 loose game resources plus the
authenticated ISO container. DMN_ABS.TXT, DMN_BIB.TXT, DMN_CPY.TXT,
DMV0.AVI, DMV1.AVI and DMV2.AVI are ISO-only members in that corpus.
They must remain virtual ISO entries until a consumer is source-bound; their
absence as loose files is not permission to create host placeholders.
File Types
Dungeon Levels (.DGN) — 16 files, 4.1 MB
LEV00.DGN through LEV15.DGN. Each 148-321 KB.
DMWeb describes each DGN as a complete level file: LEV00.DGN is the
non-playable entrance shown during the title sequence, and LEV01.DGN through
LEV15.DGN are playable levels; LEV01.DGN is the Hall of Champions.
Structure1B is a 64×64 grid with eight bytes per cell. Treat those as the
documented file roles and grid layout, not as proof that Firestaff has bound
the Saturn level loader, tile semantics, or presentation consumer.
Creature/Monster Models (.MNS) — 30 files, 1.5 MB
Named after DM1 creatures: SCORPION, MUMMY, GHOST, ROCKPILE, SCREAMER, RAT, WORM, OITU, GOLEM, GIGGLER, CHAOS, VEXIRK, etc. Plus dragons: D_RED, D_GOLD, D_SILVER, GRN_DRA, MINI_DRA, RED_DRA. These are 3D polygon models with textures for each creature type.
Sound/Audio per Level (.SAL + .MAP) — 32 files, 5.9 MB
SNDLEV00-15.SAL (290-460 KB each): sound effect banks per level. SNDLEV00-15.MAP (66-90 bytes each): sound mapping tables.
Video (.AVI) — 3 files, 101 MB
DMV0.AVI (34 MB), DMV1.AVI (28 MB), DMV2.AVI (39 MB). Their runtime playback roles and decoder/presentation path have not been established from the current source joins.
Level Supplementary (.BIN + .BIN) — 32 files
SLEV00-15.BIN (2-12 KB): per-level task candidates with bounded SH-2/source receipts; event meaning unproven. SMAP00-15.BIN (17-30 KB): level minimap/automap data.
Core Game Data (.BIN) — 15 files
DM.BIN (542 KB): main game executable/data — the big one. 0DMSTRT.BIN (39 KB): startup data. TITLE.BIN (110 KB): title screen. WARNING.BIN (99 KB): warning/disclaimer screen. GAMEOVER.BIN (101 KB): game over screen. FACE.BIN (44 KB): champion face portraits. DEATH.BIN (4 KB): death sequence data. STONE.BIN (4 KB): stone/wall texture base. NBG3.BIN (7 KB): VDP2 background layer. POTEFT.BIN (3 KB): potion effects. RHIFIX.BIN (5 KB): unknown fix data. RLOWFIX.BIN (71 KB): RES* archive with source-bound champion PLRD, creature CRET, and text/TABL resources; Japanese, English, and French identities are recorded separately where verified. Runtime semantics remain gated by their individual consumers. STABG.BIN (52 KB): status area background. SWTCHR.BIN (38 KB): switch/lever graphics.
Graphics
TITLE.CG (164 KB): title screen color graphics. LOGOBG.DG2 (71 KB): logo background. The Japanese, English, and French retail revisions are hash-identified separately; the French PP member decodes to 320x224. Source and format validation do not establish its Saturn placement. FONT256.S2D (24 KB): Saturn SCR/page data with 242 authenticated CG tiles; glyph mapping unproven. ITEM.IBS (98 KB): item icon/bitmap set.
Other
TM.BIN (156 KB): retail byte/hash receipt; texture/tilemap consumer unbound. MENU.BPK (87 KB): menu graphics packed. SDDRVS.TSK (26 KB): sound driver task. DMN_ABS.TXT, DMN_BIB.TXT, DMN_CPY.TXT: tiny text files.
Key Findings
- 16 dungeon levels (same count as DM1) — confirms the corpus contains LEV00–LEV15, but does not by itself prove shared runtime format or mechanics
- 30 creature models — the retail corpus contains 30 named model assets; matching names do not prove DM1 runtime ownership or behavior
- Per-level sound banks — each level has an associated SAL/MAP pair; selector ownership and playback semantics remain capture-gated
- DM.BIN (542 KB) — likely the game logic/engine binary (SH2 code)
- 3 FMV cutscenes — Saturn AVI format
- FONT256.S2D — 256-character font (includes Japanese)
- Same creature names as DM1 — SCORPION, MUMMY, GHOST, etc.
