Doom RPG RE — 3DS v1.0.3

New 3DS home-menu build (.cia) and 3DSX package of Doom RPG RE, following v1.0.2. Source-only: no game assets or audio are bundled in the repository. They are supplied on the SD card (see Install).

  • Build: 2026-09-02
  • Version: 1.0.3
  • Title ID: 000400000FD0BB01

Overview

Version 1.0.3 is a major feature and performance release that takes full advantage of Nintendo 3DS hardware. It brings hardware autostereoscopic 3D to the top screen, an interactive bottom-screen Touch HUD with an in-game quick-inventory hotbar, a touch keypad for entering terminal passcodes, Play Coins exchange, in-memory MP3 music streaming via libmad, and New 3DS 804 MHz CPU boost.

What Changed

Area Change
Autostereoscopic 3D Implemented a true dual-camera stereoscopic 3D rendering pipeline using Citro2D/Citro3D GPU targets. The depth effect is hardware-gated and dynamically scaled by the physical 3DS 3D slider (smoothly drops to single-eye 2D when the slider is off). Depth separation has been carefully tuned across world geometry, particles, and weapon parallax to eliminate ghosting and eye strain. Menus and 2D splash states automatically disable 3D rendering.
Touch HUD & Hotbar Added authentic metallic steel status bars to the bottom screen matching the top HUD aesthetic. Features an interactive 5-slot quick-use hotbar (S.MED, L.MED, SOUL, BRSK, DOG) with generous 80px touch targets, plus touch [ PASS ] and [ MENU ] buttons. Font kerning is compensated for the 3DS 320px downscale with transparent font blitting over metallic textures.
Interactive Touch Keypad Terminal passcode doors now display an authentic on-screen touch numpad (0–9, C, OK) on the bottom screen, allowing players to enter door codes naturally using the stylus or thumb.
MP3 Music Streaming Rewrote the audio streaming engine using libmad to decode MP3 tracks (5039.mp3, 5040.mp3, 5043.mp3) directly from memory. Compressed MP3 files (1.5–4.1 MB) are cached into RAM once at track start, eliminating all SD card file I/O inside the real-time SDL audio callback thread and preventing 3DS FS session deadlocks. Supports seamless looping and full volume scaling from the in-game Options menu.
Bottom Screen Dialogs Dialogue sequences, terminal readouts, and character interaction popups now render cleanly on the bottom screen (scaled 2x with 280px width) over the persistent automap, keeping the top 3D screen uncluttered.
Navigation & Controls The B button now functions as Back / Return in all menus and dismisses dialog boxes. Circle Pad analog inputs are fully supported alongside the D-pad. Unified hidScanInput polling to eliminate dropped inputs when holding multiple buttons.
3DS Play Coins Exchange Players can exchange Nintendo 3DS system Play Coins for game Credits ($50 credits per Play Coin) at shops and terminals.
New 3DS Performance Enabled 804 MHz clock speed and L2 cache configuration via RSF for New 3DS systems. Defaulted floor and ceiling rendering to solid mode to avoid costly per-pixel textured projection, maintaining smooth framerates.

Install

  1. Install DoomRPG-1.0.3.cia with FBI (or run DoomRPG.3dsx from the Homebrew Menu).
  2. On the SD card, copy the extracted data files into sdmc:/3ds/doomrpg/ so they sit loose in that folder. Required files include the *.bmp sprites/UI, the *.bsp maps, wtexels.bin, stexels.bin, bitshapes.bin, palettes.bin, mappings.bin, and sintable.bin.
  3. Add audio next to the data, also under sdmc:/3ds/doomrpg/:
    • SFX as numbered .wav files (5042.wav through 5138.wav).
    • Music as numbered .mp3 files (5039.mp3, 5040.mp3, 5043.mp3).
  4. Launch from the HOME Menu. sdmc:/3ds/doomrpg/saves/ is created at runtime.

The game will not start unless sdmc:/3ds/doomrpg/ exists with the data files present.

Notes & Compatibility

  • Recommended for New 3DS (New 3DS, New 3DS XL, New 2DS XL) to take advantage of 804 MHz CPU clock speed and hardware stereo 3D.
  • Autostereoscopic 3D operates on the top screen and is continuously adjusted by the 3DS hardware depth slider.
