 ## Building
+
+SDL2 is used by default on desktop platforms and Emscripten. Pass
+`-DXSYSTEM35_SDL_VERSION=3` to CMake to select SDL3. Use a separate build
+directory for each SDL version.
+
+The supported configurations are:
+
+| Platform | SDL2 | SDL3 |
+| --- | --- | --- |
+| Linux and macOS | Yes | Yes |
+| Windows 64-bit | Yes | Yes |
+| Windows 32-bit | Yes | No |
+| Emscripten | Yes | Yes |
+| Android | No | Yes |
+
+SDL2 builds require SDL 2.18 or later and SDL2_mixer. SDL3 builds require
+SDL 3.4 or later and SDL3_mixer 3.2 or later. The remaining common
+dependencies are FreeType, zlib, and optionally libwebp, PortMidi, and cJSON.
+
 ### Linux (Debian / Ubuntu)
 
 ```bash
-$ sudo apt install build-essential cmake libgtk-3-dev libsdl2-dev libsdl2-ttf-dev libsdl2-mixer-dev libwebp-dev libportmidi-dev libcjson-dev asciidoctor
-$ mkdir -p out/debug
-$ cd out/debug
-$ cmake -DCMAKE_BUILD_TYPE=Debug ../../
-$ make && make install
+$ sudo apt install build-essential cmake libsdl2-dev libsdl2-mixer-dev \
+    libfreetype-dev libwebp-dev libportmidi-dev libcjson-dev asciidoctor
+$ cmake -S . -B out/sdl2 -DCMAKE_BUILD_TYPE=Debug \
+    -DXSYSTEM35_SDL_VERSION=2
+$ cmake --build out/sdl2
+$ sudo cmake --install out/sdl2
 ```
 
+For SDL3 on a distribution that provides SDL 3.4 or later (for example,
+Ubuntu 26.04), install `libsdl3-dev` instead of the SDL2 packages and
+configure `out/sdl3` with `-DXSYSTEM35_SDL_VERSION=3`. If SDL3_mixer 3.2 or
+later is installed, CMake uses it; otherwise, CMake downloads and builds
+SDL3_mixer 3.2.4 during configuration.
+
 ### MacOS
 
 [Homebrew](https://brew.sh/) is required.
 
 ```bash
-$ brew install cmake pkg-config sdl2 sdl2_mixer sdl2_ttf webp portmidi cjson asciidoctor
-$ mkdir -p out/debug
-$ cd out/debug
-$ cmake -DCMAKE_BUILD_TYPE=Debug ../../
-$ make && make install
+$ brew install cmake pkg-config sdl2 sdl2_mixer freetype webp portmidi \
+    cjson asciidoctor
+$ cmake -S . -B out/sdl2 -DCMAKE_BUILD_TYPE=Debug \
+    -DXSYSTEM35_SDL_VERSION=2
+$ cmake --build out/sdl2
+$ sudo cmake --install out/sdl2
 ```
 
+For SDL3, install `sdl3 sdl3_mixer` instead of `sdl2 sdl2_mixer` and
+configure `out/sdl3` with `-DXSYSTEM35_SDL_VERSION=3`.
+
 ### Windows
 
 [MSYS2](https://www.msys2.org) is required.
 
 ```bash
-$ pacman -S cmake mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-SDL2 mingw-w64-ucrt-x86_64-SDL2_ttf mingw-w64-ucrt-x86_64-SDL2_mixer mingw-w64-ucrt-x86_64-libwebp mingw-w64-ucrt-x86_64-portmidi mingw-w64-ucrt-x86_64-cjson
-$ mkdir -p out/debug
-$ cd out/debug
-$ cmake -G"MSYS Makefiles" -DCMAKE_BUILD_TYPE=Debug ../../
-$ make
+$ pacman -S mingw-w64-ucrt-x86_64-gcc \
+    mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-SDL2 \
+    mingw-w64-ucrt-x86_64-SDL2_mixer mingw-w64-ucrt-x86_64-freetype \
+    mingw-w64-ucrt-x86_64-libwebp mingw-w64-ucrt-x86_64-portmidi \
+    mingw-w64-ucrt-x86_64-cjson
+$ cmake -S . -B out/sdl2 -G"MSYS Makefiles" \
+    -DCMAKE_BUILD_TYPE=Debug -DXSYSTEM35_SDL_VERSION=2
+$ cmake --build out/sdl2
 ```
 
+For a 64-bit SDL3 build, install `mingw-w64-ucrt-x86_64-sdl3` and
+`mingw-w64-ucrt-x86_64-sdl3-mixer` instead of the SDL2 packages, then
+configure `out/sdl3` with `-DXSYSTEM35_SDL_VERSION=3`. The MSYS2 mingw32
+repository does not provide SDL3, so 32-bit Windows builds remain on SDL2.
+
 ### Emscripten
 
 ```bash
-$ mkdir -p out/wasm
-$ cd out/wasm
-$ emcmake cmake -DCMAKE_BUILD_TYPE=MinSizeRel ../../
-$ make
+$ emcmake cmake -S . -B out/wasm-sdl2 -DCMAKE_BUILD_TYPE=MinSizeRel \
+    -DXSYSTEM35_SDL_VERSION=2
+$ cmake --build out/wasm-sdl2
 ```
 
+For SDL3, use a different build directory and
+`-DXSYSTEM35_SDL_VERSION=3`. Both versions use Emscripten's bundled SDL port;
+SDL_mixer is not required.
+
 To use the generated binary, check out

+
+## Usage
+### Basic Usage
+You can install games either from a prepared ZIP file or directly from a CD-ROM
+image.
+
+#### Installing from a ZIP
+1. Create a ZIP file containing all the game files and BGM files (see
+   [below](#preparing-a-zip) for details), and transfer it to your device.
+2. Open the app. Tap the option menu (three dots in the top right corner) and
+   select "Install from ZIP".
+3. Select the ZIP file you created in step 1.
+4. The game will start.
+
+#### Installing from a CD image
+1. Transfer the CD image file(s) to your device.
+2. Open the app. Tap the option menu and select "Install from CD image".
+3. Select the image file and, when needed, the matching metadata file at the
+   same time. The supported combinations are:
+   - `.iso`
+   - `.bin` or `.img` with matching `.cue`
+   - `.bin` or `.img` with matching `.ccd`
+   - `.mdf` with matching `.mds`
+
+   In many Android file pickers, tapping a file immediately selects only that
+   one file. Long-press a file first to enter multi-select mode, then select
+   both the image file and its metadata file.
+4. The game will start.
+
+### Preparing a ZIP
+- Include all files from the `GAMEDATA` folder (such as `.ALD` files and
+  others). `.EXE` and `.DLL` files are not necessary, but you can include them
+  if you want.
+- Music files (`.mp3`, `.ogg`, or `.wav`) whose filenames have a number either
+  at the beginning or just before the extension are recognized as BGM files.
+  For example:
+  - `Track2.mp3`
+  - `15.ogg`
+  - `02 - Title.mp3`
+  - `rance4_03.wav` (Note: The filename shouldn't be `rance403.wav`, as it
+    would be treated as the 403rd track.)
+
+Note: This ZIP format is also compatible with
+[Kichikuou on Web](http://kichikuou.github.io/web/).
+
+### Miscellaneous
+- To simulate a right-click, tap the black bars on either the left or right,
+  or top or bottom of the screen.
+- You can export or import save files via the game list's option menu.
+- To uninstall a game, long-tap its title in the game list.
+
+## Known Issues
+- Android versions older than 7.0 cannot handle ZIP files containing Shift-JIS
+  filenames. This issue occurs with some ZIP files distributed on
+  [retroc.net](http://retropc.net/alice/). If you encounter the error message
+  "This type of ZIP is not supported," unzip the file on your PC and re-archive
+  it using modern ZIP creation software.
+
+## Building from Source
+
+Android builds use SDL3 exclusively. Gradle downloads the fixed official SDL3
+3.4.16 and SDL3_mixer 3.2.4 AARs, verifies their checksums, and supplies their
+native libraries to CMake through Prefab. No separate SDL installation is
+required.

+# Censor Lists for Streamer Mode
+
+This directory contains sample censor lists for various games, intended for use
+with xsystem35's Streamer Mode.
+
+## Usage
+
+To use a censor list, specify its path with the `-censor` command-line option
+or in your `.xsys35rc` file. For example:
+
+```bash

+```
+
+The list files contain image numbers (integers), one per line. A `#` starts a
+comment that continues to the end of the line.
+
+## Contributing
+
+We welcome contributions of censor lists for other games! If you have created
+a censor list that you'd like to share, please open a Pull Request.
