Dungeon Master Nexus

Dungeon Master Nexus is the Saturn version of Dungeon Master. It uses Saturn assets, DGN dungeon data, BPK/PRS-style graphics, scripts, audio, and a different startup path from the PC games.

How to Play

Start Firestaff, choose Dungeon Master Nexus, then press Start. Use the title and champion/startup flow to reach the dungeon route supported by the current build.

Controls

  • Arrow keys: move and turn where keyboard movement is active.
  • W, A, S, D: movement layout controls.
  • Q / E: turn left/right.
  • Mouse: select menus, champion/start options, and supported runtime UI areas.
  • Controller/Steam Deck: map the D-pad or stick to movement, face buttons to confirm/cancel, and shoulder buttons to turning.

Game Data

Put your legally owned Nexus data under:

~/.firestaff/data/nexus/

Firestaff accepts the original CUE/BIN/ISO layout, or a supported ZIP/7z disc container. For ZIP media, its embedded CUE selects the declared TRACK 01 MODE1 file, rather than relying on archive order. Firestaff reads that member in memory and never unpacks game-data members to disk. A ZIP-only verification using the Japanese retail archive opened all 137 Track 1 files and completed the native launch smoke receipt; the test directory contained only a symlink to the original archive.

Extracted Saturn files remain supported, but are not required. Firestaff scans retail identities by hash, so a clean nexus folder still makes it easier to diagnose missing or mismatched media.

Important data may include Saturn title/menu graphics, DMDF data, DGN levels, BPK/PRS graphics, scripts, and audio assets.

Saves

Nexus save handling is built separately from the original media. Keep any original Saturn save exports backed up before testing import or conversion.

Notes

Nexus support is active around champion startup, save paths, DGN mesh rendering, package/host-route consumption, and Saturn timing/capture. If startup shows garbage graphics, verify that the expected Saturn data is present and that the build is current.
