+
+## 2.9.0 - 2023-05-04

+- Fixed a bug where SACT games (e.g. Rance 5D) were not responding to touch.

+- Windows: Added a menu command to enable/disable automatic mouse movements.
+
+## 2.5.1 - 2022-07-31
+- Implemented "palette shift" graphic effect (used in 闘神都市II).

-
-  --with-cachesize=xxxx
-     データキャッシュの大きさを指定します。単位は MB で、デフォルトは 20MB
-     です。データのほとんどは展開済み CG のキャッシュに使われます。シナリオ
-     などのデータは mmap を使っていますので、キャッシングは xsystem35 の管理
-     外です。
-
-  --enable-mmx
-     IA32 プラットフォームで MMX を使うようにします。nasm というアセンブラが
-     必要になります。IA32 ではデフォルトで有効にします。無効にする場合は =no
-     を指定して下さい。実行時に MMX 命令が使用可能かどうかチェックしますので、
-     MMX 命令を持たないCPUでも有効のままでかまいません。
-
-  --enable-debug
-     debuging を有効にします。
-     有効にしてコンパイルすると -debuglv # オプションが使えるようになります。
-     debug level に関しては src/xsystem35.h を参照して下さい。
-
-## (*1) 実行時に読み込む設定ファイル ~/.xsys35rc でも指定できます。
-
-
-  参考: 私の開発時の configure オプション(実際には１行です)

 # xsytem35-sdl2

-This is a multi-platform port of xsystem35, a free implementation of AriceSoft's System3.x game engine.
+This is a multi-platform port of `xsystem35`, a free implementation of
+AliceSoft's System 3.x game engine.

-## Download
-Prebuilt binaries for Windows and Android can be downloaded from the [Releases](https://github.com/kichikuou/xsystem35-sdl2/releases) page.
+## Compatibility

-## Build
+See the [game compatibility table](game_compatibility.md) for a list of games
+that can be played with xsystem35-sdl2.
+
+## Unique Features
+
+In addition to the original System 3.x functionalities, xsystem35-sdl2 offers
+the following features:
+
+### Playing Audio Files as Virtual CD Music
+
+Many System 3.x games feature music as audio tracks on the CD-ROM. xsystem35
+can play music from audio files, eliminating the need to insert CDs. Supported
+audio file formats are MP3 and Ogg. To use ripped audio files, create a file
+named `playlist.txt` in the game directory and list the paths to your tracks,
+one per line. For example:
+
+```
+# The first line is not used
+BGM/track02.mp3
+BGM/track03.mp3
+...
+```
+
+The first line is not used because the first track on a game CD is typically a
+data track.
+
+Some games have integrated music as MIDI. In such cases, the music won't play
+using the virtual CD feature. If you encounter a `Cannot load MIDI` error
+message, you might need to set the `SDL_SOUNDFONTS` environment variable to
+point to an `.sf2` file. For example:
+
+```
+SDL_SOUNDFONTS=/usr/share/soundfonts/GeneralUser.sf2 xsystem35
+```
+
+### Unicode Translation Support
+
+While the original System 3.x only supported Shift_JIS (a Japanese character
+encoding), xsystem35 supports Unicode and can run games translated into
+languages other than Japanese and English.
+
+For instructions on how to build a game with Unicode support, see the
+[xsys35c](https://github.com/kichikuou/xsys35c) documentation.
+
+### Debugging
+
+xsystem35 features a built-in debugger that allows you to step through the game
+and examine or modify game variables. There are two ways to use the debugger:
+
+- Through [Visual Studio Code](https://code.visualstudio.com/) (recommended):
+  The [vscode-system3x](https://github.com/kichikuou/vscode-system3x) extension
+  provides a graphical debugging interface for System 3.x.
+- Using the CLI Debugger: Running xsystem35 with the `-debug` option will
+  launch the debugger with a console interface. Type `help` to see a list of
+  available commands.
+
+### Streamer Mode
+
+xsystem35 introduces a "Streamer Mode" to make playing games with NSFW content
+safer for streaming or public viewing. When enabled with the `-censor <file>`
+option, images specified in the provided file will be automatically mosaiced.
+
+The `misc/censor/` directory contains example censor list files for some games.
+
+## Installation
+
+Prebuilt packages for Windows and Android can be downloaded from the
+[Releases](https://github.com/kichikuou/xsystem35-sdl2/releases) page.
+
+Note for Windows:
+- The 64-bit version supports Windows 10 or later. For older versions of
+  Windows, please use the 32-bit version.
+- Debugging is supported only in the 64-bit version.
+
+For other platforms, refer to the [Building](#building) section.
+
+## Running
+### Windows
+
+Copy `xsystem35.exe` to the game folder and run it.
+
+### Android
+
+See [android/README.md](android/README.md#usage).
+
+### Other Platforms
+
+Run xsystem35 from within the game directory.
+
+```bash
+$ cd /path/to/game_directory
+$ xsystem35
+```
+
+See [xsystem35 command manual](doc/xsystem35.6.adoc) for detailed usage.

 # xsystem35 for Android

-## Download
-Prebuilt APKs are [here](https://github.com/kichikuou/xsystem35-sdl2/releases).
+Minimum supported Android version: 5.0

-## Build
-Prerequisites:
- CMake >=3.13
- Android SDK >=28
- Android NDK >=r15c
+## Download
+You can download prebuilt APKs
+[here](https://github.com/kichikuou/xsystem35-sdl2/releases).
+
+### Installing with Obtainium
+Alternatively, you can install `xsystem35-sdl2` using [Obtainium](https://github.com/ImranR98/Obtainium). Obtainium will detect new releases and allow you to update the app directly.
+
+1. Install Obtainium on your Android device.
+2. Click the badge below to add the app to Obtainium:
+
+   [<img src="https://raw.githubusercontent.com/ImranR98/Obtainium/main/assets/graphics/badge_obtainium.png" alt="Get it on Obtainium" height="60">](https://apps.obtainium.imranr.dev/redirect?r=obtainium://app/%7B%22id%22%3A%22io.github.kichikuou.xsystem35%22%2C%22url%22%3A%22https%3A%2F%2Fgithub.com%2Fkichikuou%2Fxsystem35-sdl2%22%2C%22author%22%3A%22kichikuou%22%2C%22name%22%3A%22xsystem35%22%2C%22categories%22%3A%5B%22games%22%5D%7D)
+
+## 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.

 ```
-
-## Use
-### Basic Usage
-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. A list of installed games is displayed. Since nothing has been installed yet, only the "Install from ZIP" button is displayed. Tap it.
-3. Select the ZIP file you created in 1.
-4. The game starts. Two-finger touch is treated as a right click.
-
-### Preparing a ZIP
- Include all files in the `GAMEDATA` folder (`.ALD` files and others). `.EXE` and `.DLL` are not really needed, but you can include them as well.
- Music files (`.mp3`, `.ogg` or `.wav`) whose file names end with a number are recognized as BGM files. For example:
-  - `Track2.mp3`
-  - `15.ogg`
-  - `rance4_03.wav` (This shouldn't be `rance403.wav`, because it would be treated as the 403rd track)
-
-Note: This form of ZIP can be used in [Kichikuou on Web](http://kichikuou.github.io/web/) as well.
-
-### Miscellaneous
- You can export / import saved files using the option menu of the game list.
- To uninstall a game, long-tap the title in the game list.

-2. 使い方
-
-   ゲームのCD-ROMをドライブに入れてマウントし、
- %  ./instgame kichiku.inf
- のように実行します。
-
-   デフォルトではCDROMは/cdromにマウントされているものとしています。
- また、データのインストール先は ~/game/kichiku/ の下になります。
-
-   デフォルトでは設定用ファイルのファイル名が~/game/の下のディレクトリ名に
- なります。
-
-  これらのデフォルトの条件を変えるには以下のオプションを使います。
-
-  -c : CD-ROMのマウントされている位置を指定します(default: -c /cdrom)
-  -d : ゲームデータのインストール先を指定します  (default: -d ~/game/target>)
-
-   データが正常にコピーされると、~/game/の下にkichiku.grと言うファイルが作成
- されます。これはゲームデータの場所をプログラム(xsystem35)に知らせるためのも
- ので、
- % xsystem35 -gamefile ~/game/kichiku.gr
- のように指定するのに使います。(「ゲームリソースファイル」とでも呼んで下さい)
-
-   デフォルトでは、*.grというファイルも設定用ファイルのファイル名と同じ名前に
- なりますが、以下のオプションで変更可能です。
-
-  -g : ゲームリソースファイルのファイル名を指定します
-       (default: -g ~/game/<target>.inf)
-
-
-3. その他の情報
-
-   その他のオプションに、指定のファイルはCD-ROMからコピーせずにリンクを張る、
- という指定が出来ます。
-
- % ./instgame -k Graphics kichiku.inf
-
- とすると、kichiku_ga.ald と kichiku_gb.ald のファイルはコピーされずに、
- CD-ROM上のデータへのシンボリックリンクになります。ただし、そうするとゲーム中
- はCD-ROMをマウントしておかなければならないので、CD-ROMをマウントしたまま
- CD-DAの演奏可能な一部のシステムでのみ可能です。
-
-
-   このオプションはゲームデータのインストール時の動作を規定するものなので、
- 自分でCD-ROMからファイルをコピーして、ゲームリソースファイルをエディタで
- 編集すれば、全く自由にデータの配置を行なう事が出来ます。もちろん、ゲーム
- リソースファイルのファイル名や置き場所も自由にして出来ます。
- ゲームリソースファイルの書式については doc/GRFMT.TXT を御覧下さい。

-                  ゲームリソースファイル(*.gr)の書き方
-
-
-   xsystem35ではゲームデータの置き場所をテキストファイルに保存しておき、
- それをxsystem35に指定してやる事でデータの置き場所を知らせます。
-
-# このファイルのファイル名はxsystem35を起動する時に指定できますので、hoge.gr
-# である必要は無く、自由につける事が出来ます。
-
- ここでは、このテキストファイル(ゲームリソースファイル)の書式を説明します。
-
-
-  １つのデータにつき１行で記述します。例を見て下さい。
-
-  ScenarioA /home/chikama/game/rance4/rance4_sa.ald
-
-    キーワード データのフルパス
-
- の順に書きます。キーワードは行の先頭から書き、データのフルパスとの間は半角
- スペースです。(セーブデータのみ、ホームディレクトリを表す ~ を評価します。)
- 
- キーワードには次の７つがあります。
-
-    Scenario : シナリオ
-    Graphics : グラフィック
-    Wave     : PCMデータ
-    Midi     : MIDIデータ
-    Data     : その他データ
-    Save     : セーブデータ
-    Resource : リソースファイル(マウスカーソル形状)
-    Ain      : DLL とその関数の情報のかかれた System39.ain
-    BGM      : BGMデータ(エスカレイヤー以降のBGMデータファイル)
-    WAI      : PCMデータの追加情報 (mixer channel 情報等)
-    BGI      : BGMデータの追加情報 (ループ位置等)
-    SACT01   : SACT.DLL用データ (SACTEFAM.KLD)
-    ALK      : デモ用アーカイブファイル
-    Init     : System39.ini
-   
- 同じ種類のデータが複数ある場合はキーワードの次にA,B,C...をつけます。
- (Ain を除く)
-
-   CD-ROM上のどれがどの種類のファイルかは、ファイル名で判別します。
- *SA.ALD ならシナリオの１番目、*GA.ALDはグラフィック、*WA.ALDはPCM、
- *MA.ALD はMIDI、*DA.ALDはその他データです。
-
-   Ain は System39.ain へのパスを書きます。例えば
- Ain /home/chikama/game/20cKaeru/System39.ain
- のように書きます。
-
-   Init は System39.ini へのパスを書きます。例えば
- Init /home/chikama/game/esuka/System39.ini
- のように書きます。
-
-   WAI/BGI は通常１ファイルだけですので
- WAIA /home/chikama/game/esuka/DOKI_WA.WAI
- BGIA /home/chikama/game/esuka/DOKI_BA.BGI
- のように書きます。
-  
-   SACT01 は SACTシステム固有のデータファイル(SACTEFAM.KLD)へのパスを
- 指定します。
- SACT01 /home/chikama/game/rance5d/SACTEFAM.KLD
-
-   ALK はデモ用のデータが入ったアーカイブファイルです。
- ALK01 /home/chikama/game/nd/NightDemonDemo1.alk
- ALK02 /home/chikama/game/nd/NightDemonDemo2.alk
- ALK03 /home/chikama/game/nd/NightDemonDemo3.alk
- のように書きます。
-
-
-  また、これらの範疇にはいらないデータ、たとえば、かえるにょぱにょんの
- floor_1.mapなどはリソースファイルを介しませんので、ゲームリソース
- ファイルには書かず、「セーブデータを置いたディレクトリと同じ場所」に
- コピーして下さい。
-
-   また、Save? のみ、'~' (ホームディレクトリ)を評価しますので、
- SaveA ~/savedata/kichiku/kichiku_sa.ald
- のように書く事が出来ます。
-
- コメントを書く場合は行頭に # をつけます。また空白行は無視されます。

-2. 開発環境と動作確認環境
-
- 2.a. 開発環境
-
-   Kondara-1.2 (Linux/i386)
-
- 2.b. 動作確認環境
-
-   DigitalUnix 4.0F (alpha)
-   SunOS 5.8 (sparc)
-
- 2.c. 多分動くと思われる環境
-
-   Linux(!i386)
-   FreeBSD/NetBSD/OpenBSD (i386 etc)
-   Irix 6.X
-   Solaris 2.X 以降 (sparc/i386)
-
-
-3. xystem35の設定ファイル
-
-   xsystem35ではフォントの設定などを、カレントディレクトリとホームディレクトリに
- ある .xsys35rcというファイルから読み込みます。カレントディレクトリの .xsys35rc
- に書かれた設定のほうが優先されるため、一般的な設定はホームディレクトリの
- .xsys35rcに書き、特定のゲームで書き換えたい項目はゲームを置いたディレクトリの
- .xsys35rcに書くといいでしょう。
-
-   サンプルとなるファイルを xsys35rc.sample として用意しました。
-
-   また、gtk widgetのリソースは ~/.gtk/gtkrc または ~/.gtkrc から読み込みます。
- 読み込み先は .xsys35rc で指定できます。
-
-   ゲームで使用するフォントは X のフォントの仕組を使う方法と、TrueTypeFontを
- 外部ライブラリを使って直接表示する方法の２種類が選べます。
- 
- ~/.xsys35rc の ttfont_mincho: と ttfont_gothic: の場所にフォントファイルを
- 指定し、font_device: ttf と指定してください。詳しくはサンプルファイル
- (xsys35rc.sample)を見て下さい。
-
-
-4. ゲームの実行と終了
-
- 4.a. ゲームの実行
-
-    instgameを使ってゲームデータをインストールすると、インストールした
-  ディレクトリにの一つ上に ???????.gr というファイル(ゲームリソースファイル)
-  が自動的に作成されますので
-
-  % xsystem35 -gamefile ~/game/???????.gr
-
-  のように実行します。-gamefile オプションをつけない場合は、カレントディレク
-  トリの xsystem35.gr を参照します。
-
-    またいずれも見つからない場合は、カレントディレクトリにあるファイルをゲーム
-  データとして設定します。例えば testSA.ALD というファイルがカレントディレク
-  トリにあると、それをシナリオデータとして使います。またセーブデータは適当な
-  名前で 10個確保されます。
-
-  ゲームリソースファイルの書き方については、doc/GRFMT.TXT を御覧下さい。
-
- 4.b. ゲームの終了
-
-   * 起動した端末で Ctrl+C を押すと、すぐに終了します。
-
-   * ゲーム中にマウスの真中のボタンを押すと、メニューが出て来ますので、
-   そこから 'Exit' を選んで終了させて下さい。Window Manager のCloseボタンでも
-   同じように動作します。
-
-   * ESC + SPACE + RET キーを同時に押すと、すぐに終了します。
-
- 4.c. xsystem35メニュー
-
-   ゲーム中にマウスの真中ボタンを押すとメニューが出て来ます。
-
-  メッセージスキップ(MessageSkip):
-        次の選択肢までメッセージを飛ばします。マウスの右クリックで
-        止まります。シナリオによっては停止しない場合もあります。
-  
-  マウスカーソル移動(MouseAutoMove):
-        選択ウィンドなどでマウスが自動的に移動するのを制御します。
-
-  ボリュームバランス(VolumeValance):
-        SACTシステムで音声の人物毎に音量を変えることができます。
-        (ゲームがそう出来るように対応している場合のみ)
-
-  情報(About):
-        このゲームについて。
-
-  終了(Exit):
-        ゲームを終了します。
-
- 4.d. キーボード操作
-
-    アリスソフトのゲームは有史来、基本的に上下左右キーに SPACE, RET, ESC, TAB
-  キーしか使いません(一部のゲームはそれ以外のキーを使うこともあります)。
-  XSystem35 では次のキー割当を特別に使っています。
-
-    F1: メッセージスキップ
-    F4: フルスクリーン <-> Window表示の切替え
-
-  また、旧き良き時代の DOS への復帰キー (ESC + SPACE + RET) でゲームを確認なし
-  で終了出来ます。  
-
-

-  「SHMMAXPGS」が関連項目です。
-
-   24bppで起動する場合は SHMMAXPGS=4096 くらいにするとよいようです。
- もちろん設定後はカーネルの再構築が必要です。

- 6.c. locale と X
-
-  libc に locale 機構が組み込まれていない環境の場合、libxpg4 などの
-  ライブラリ(FreeBSD) や X の locale を使うことになります。
-
-  linux の libc5 な環境では configure 時に --with-locale=ja_JP.ujis として
-  コンパイルしてください。
-
-  それ以外のほとんどの環境では考慮する必要はないでしょう。
