th06 3DS port

This is a Nintendo 3DS port of 東方紅魔郷　～ the Embodiment of Scarlet Devil 1.02h.

The original codebase was taken from EoSD-portable.

TODO:

• shamelessly steal the batch rendering code from th08 decomp (because the game currently doesnt do that and it runs like garbage on real hardware)
• find whichever unaligned accesses still remain
• better pre-launch check process

Usage

Important

File names for .DAT files will vary depending on the TH_LANG string in i18n.hpp.

TH_LANG is currently TH_JP

If it is TH_EN then they should be named KOUMAKYO_<name>.DAT

If it is TH_JP then they should be named 紅魔郷<name>.DAT

(you can also know which one to use by looking at the file name mentioned on the pre-launch error)

When extracting assets from an original copy of the game, they will (or at least should??) be following the notation for TH_JP, so when transfering them when TH_LANG is TH_EN, they should be renamed accordingly.

For the sake of notation, .DAT files will be referred to here as <name>.DAT rather than KOUMAKYO_<name>.DAT or 紅魔郷<name>.DAT, but when transfering to your SD card they should follow the naming convention named above.

It is important to mention that .DAT is indeed uppercase.

Place the following game assets as taken from an original copy of the game (ver 1.02h) into sdmc:/3ds/eosd3ds:

• bgm (as in the folder with the 17 .wav files inside)
• CM.DAT
• ED.DAT
• IN.DAT
• MD.DAT
• ST.DAT
• TL.DAT
• msgothic.ttc OR NotoSansJP-Regular.ttf (fonts)

Dependencies

This project has the following dependencies:

available on (dkp)-pacman:

• 3ds-zlib
• 3ds-freetype
• 3ds-libpng
• 3ds-libjpeg-turbo

build from source:

• my fork of picaGL
• SDL2
• SDL2_image
• SDL2_ttf
• makerom (optional, but required if you want to build .cia)

devkitPro doesn't ship SDL2 packages (and makerom neither) on it's pacman repository. To build them, do the following:

1. Install the other dependencies
2. Clone the repositories

git clone https://github.com/libsdl-org/\<SDL or SDL_image or SDL_ttf>.git -b SDL2 cd SDL mkdir build

3. and then build and install as instructed here

Important

For SDL2_image and SDL2_ttf, add -DSDL2IMAGE_SAMPLES=OFF and -DSDLTTF_SAMPLES=OFF (respectively) to the first cmake command. This is to prevent CMake from building the SDL2 samples, which would require extra libraries that are unnecessary here.

makerom

To build makerom, follow this and then put the executable somewhere that make can read, like $PATH, $DEVKITPRO/tools/bin or even the repository root.

Building

In the repository root directory, simply run make and the ".elf", ".3dsx" and ".cia" executables will be generated.
