Touhou 6 - Switch port

[Swiizyu]

A native homebrew port of ZUN's legendary 2002 bullet hell danmaku masterpiece Touhou 6: Embodiment of Scarlet Devil for the Nintendo Switch (Horizon OS).

Built upon the cross-platform decompilation engine GensokyoClub/th06, this port features custom hardware-accelerated OpenGL ES 3.2 rendering over Nouveau/Mesa, seamless Nintendo Switch Joy-Con and Pro Controller support, native 1280x720 window resolution scaling with pure OLED black letterbox borders, and an intelligent filename alias resolver designed for FAT32 SD cards.

Installation Guide​

Disclaimer: In compliance with ZUN's guidelines and copyright law, this repository contains ONLY the homebrew engine code. Game asset archives (*.DAT) are not distributed. You must legally own a copy of Touhou 6: Embodiment of Scarlet Devil v1.02h.

1. SD Card File Structure​

1. Ensure your Nintendo Switch is running custom firmware (Atmosphère CFW).
2. Download the latest touhou6.nro from the Releases tab (or build from source).
3. Create a folder named sd:/switch/touhou6/ on your SD card and copy touhou6.nro into it.
4. Copy the data archives from your legitimate Touhou 6 PC folder directly into the same directory:
   sd:/switch/touhou6/
   ├── touhou6.nro # Nintendo Switch homebrew executable
   ├── CM.DAT # Game data (or 紅魔郷CM.DAT)
   ├── ED.DAT # Endings data (or 紅魔郷ED.DAT)
   ├── IN.DAT # Stage intro data (or 紅魔郷IN.DAT)
   ├── MD.DAT # MIDI/Music data (or 紅魔郷MD.DAT)
   ├── ST.DAT # Stage data (or 紅魔郷ST.DAT)
   ├── TL.DAT # Title screen data (or 紅魔郷TL.DAT)
   └── msgothic.ttc # Japanese font (optional)
   (Note: Whether your files are named with full Japanese characters 紅魔郷CM.DAT or stripped ASCII CM.DAT, the engine will locate and load them automatically).

2. Enabling Background Music (BGM)​

Because Horizon OS lacks a system MIDI synthesizer, Touhou 6 plays background music on the Switch via ZUN's official WAV music mode:

1. Locate or download the standard Touhou 6 EoSD WAV BGM
2. Create a folder named bgm inside your game directory (sd:/switch/touhou6/bgm/).
3. Place all soundtrack WAV files inside bgm/.
4. Launch the game. The engine will automatically detect bgm, configure musicMode to WAV, and play full soundtrack audio. (If needed, navigate to Options -> BGM inside the game menu and set it to WAV).

3. Launching​

Run touhou6.nro from the Homebrew Menu (hbmenu), Sphaira launcher, or install a home screen forwarder shortcut.

Really cool to see this game ported, but I couldn't get it working, tried both the original and the English patched files, the game opens the loading screen for less than a second, then gets closed. The cfg file is unreadable, it just says NUL a bunch of times.
