Doom RPG RE — 3DS v1.0.7

Patch release for the 3DS home-menu build (.cia) and 3DSX package of Doom RPG RE, following v1.0.6. Source-only: no game assets or audio are bundled in the repository. They are supplied on the SD card (see Install).

  • Build: 2026-09-06
  • Version: 1.0.7
  • Title ID: 000400000FD0BB01
  • License: GPLv3

Overview

Version 1.0.7 addresses hardware input and filesystem usability feedback reported by the homebrew community:

  1. Circle Pad Backward (Down) Fix: Fixed an issue where pulling down on the Circle Pad failed to move the character backward or navigate menus down. In libctru, KEY_CPAD_DOWN is defined as BIT(31) (0x80000000), which represents a negative value when stored in a signed 32-bit int (-2147483648). The input handling loop previously checked if (kb <= 0) continue;, inadvertently discarding KEY_CPAD_DOWN as an empty slot sentinel. The loop now explicitly checks for empty slot sentinels (-1 and 0), restoring full Circle Pad backward support.
  2. Automatic Save Directory Creation: Implemented Game_ensureSaveDir() to recursively create sdmc:/3ds/doomrpg/saves on boot and prior to all file write routines. Fresh installs running exclusively via .3dsx no longer encounter fatal write errors when attempting to save game state or configuration.
  3. Repurposed SELECT Button (Automap Recenter & Zoom): The automap is permanently active on the bottom touch screen, rendering the legacy phone # map toggle obsolete. The SELECT hardware button now acts as a dedicated Automap Recenter ([CTR]). If the map is already centered, tapping SELECT cycles the zoom scale between 1x, 2x, and 3x, complete with audio chime feedback and an on-screen notification banner.
  4. Native 3DS Dialogue & UI Prompts: Automatically adapts legacy phone keypad references found in level dialogue and computer logs into native 3DS controls in real-time (e.g., * and 7 -> ZL/ZR, 0 key -> START, # key -> touch screen automap, 9 button -> B button, OK button -> A button). End-of-level summary screens, credits, and the in-game Help menu have also been refreshed for native 3DS gameplay.
  5. Documentation Clarifications: Explicitly documented entities.db and help.txt as required root asset files, and clarified that the original extraction's .mid music tracks must be converted to numbered .mp3 files (5039.mp3, 5040.mp3, 5043.mp3).

Highlights (v1.0.7)

  • Hardware Circle Pad Fix: Restored full 4-directional Circle Pad support (Up, Down, Left, Right) in both 3D exploration and 2D menu navigation.
  • Standalone 3DSX Saves: Full out-of-the-box compatibility for Homebrew Launcher users without needing manual directory creation or CIA pre-installation.
  • SELECT Recenter & Zoom: Quick-recenter and cycle automap zoom levels at any time during gameplay with SELECT.
  • Modernized Text & Prompts: No more legacy mobile keypad prompts—game logs, tutorials, and menus reflect actual 3DS hardware buttons.
  • Enhanced Installation Guide: Clearer accounting of all required loose asset files and music format conversions.

Detailed Commit Log (v1.0.7)

  • fix(input): resolve Circle Pad Down by replacing signed keycode comparison with sentinel check
  • fix(fs): automatically create sdmc:/3ds/doomrpg/saves directory at boot and on save
  • feat(controls): repurpose SELECT button to recenter automap and cycle zoom levels
  • feat(dialog): dynamically adapt legacy phone keypad prompts to native 3DS controls
  • docs: update required asset file list and MIDI-to-MP3 conversion guidance

Installation & Verification

  1. Install DoomRPG-1.0.7.cia with FBI (or run DoomRPG.3dsx from the Homebrew Menu).
  2. Copy extracted assets directly into sdmc:/3ds/doomrpg/:
    • entities.db and help.txt
    • Maps: *.bsp (e.g. junction.bsp, sector1.bsp, etc.)
    • Binary tables: wtexels.bin, stexels.bin, bitshapes.bin, palettes.bin, mappings.bin, sintable.bin
    • Graphics: *.bmp UI and sprite sheets
  3. Copy audio into sdmc:/3ds/doomrpg/:
    • Sound effects: numbered .wav files (5042.wav through 5138.wav)
    • Music tracks: converted .mp3 files (5039.mp3, 5040.mp3, 5043.mp3)
  4. Launch from the HOME Menu or Homebrew Launcher. The saves/ folder will be created automatically.
