• Hardware Gamma Correction:
  • Official Doom GAMMATBL lookup tables integrated into the 3DS display driver.

  • 3D filled progress bars for Health, Armor, and Dual Blue/Green Mana.
  • Interactive touch Artifact Tray and weapon selectors.

  • Bottom screen (320x240) real-time tactical automap with persistent discovered item markers, enemy radar blips, and quick action buttons ([WADS], [SAVE], [LOAD], [ZOOM]).
