+## 2.11.2 - 2024-04-10
+- Added `-savedir` option to specify save directory.
+- Android: Fixed a bug where .xsys35rc in a subdirectory of ZIP was not loaded. (#51)
+
+## 2.11.1 - 2024-02-18
+- Windows: Fixed a black screen issue in the MangaGamer version of Rance 5D (#45).
+- Fixed a crash bug in command-line debugger.
+
+## 2.11.0 - 2024-01-20
+- Windows: Now `xsystem35.exe` is a standalone executable. You can just copy it to the game folder and run it.
+- Windows: The installer is no longer provided. If you have an earlier version installed, please uninstall it.
+- Windows: The debugger is no longer available in the 32-bit version. Please use the 64-bit version if you need it.
+- Added experimental `enable_zb` option (#44). See `xsys35rc.sample` for details.
+
+## 2.10.1 - 2024-01-01
+- Windows: Added "Integer Scaling" menu option
+- Fixed initial palette colors (to match System3.9)
+- Fixed a bug where palette 246 to 249 were unintentionally changed after loading 256-color CGs
+
+## 2.10.0 - 2023-12-09
+- Breaking change: A [bug](https://github.com/kichikuou/xsystem35-sdl2/issues/41) has been fixed in which save format for 大悪司 and かえるにょ国にょアリス was not compatible with System3.9. As a result, save files for these games created with older versions of xsystem35 are no longer usable. (Loading will not fail, but wrong values will be loaded.)
+- Now the 64-bit executable supports Windows 10 or later. For older Windows, please use the 32-bit version.
+- Fixed a problem with the download edition of Daiakuji requiring insertion of Disk 2. (#43)
+- Debugger: Added debug commands for monitoring the color palette.
+- Minor bug fixes.
+
+## 2.9.1 - 2023-06-22

+- Debugger: Now breakpoints do not make the window completely unresponsive
+- Debugger: Fixed a conditional breakpoint crash bug
+
+## 2.9.0 - 2023-05-04
+- Now xsystem35 uses the System3.9 save file format (unless `-saveformat` command line flag is specified). Old save files can still be loaded.
+- Changed the default naming convention for save files from `[a-z]sleep.asd` to `<gamename>s[a-z].asd`.
+- Fixed a bug where SACT games (e.g. Rance 5D) were not responding to touch.

+
+## 2.8.0 - 2023-02-12
+- Added support for Rance 4.1/4.2 ver1.05
+- Fixed movement animation in rooms in Rance 4 v2.05 (#35)
+- Added `-game` option which can be used to enable game-specific hacks in translated games
+
+## 2.7.0 - 2023-01-28
+- Added support for Rance4 ver.2.05
+- Now supports BGM playback for the download edition of Daiakuji
+- Bug fixes
+
+## 2.6.0 - 2023-01-01
+- Android: Introduced a new way to simulate right-click; tapping on the black bars at the left/right or top/bottom of the screen is treated as a right click. (Two-finger touch, the old way to simulate a right click, still works.)
+- 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).
+- Implemented `grDrawFillCircle` command (used in グレイメルカ).

+- Android: Enabled joystick input.
+- Debugger improvements.
+
+## 2.2.0 - 2021-12-03
+From now on, the Android and Windows versions will use a common version number.
+
+- Android: Use custom fonts specified in `.xsys35c`. (#20)

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

+## Compatibility
+
+See the [game compatibility table](game_compatibility.md) for a list of games
+that can be played with xsystem35-sdl2.

+In addition to the original System 3.x functionalities, xsystem35-sdl2 offers

+### Playing Audio Files as Virtual CD Music

-Many System 3.x games had music as audio tracks on the CD-ROM. Xsystem35 can
-play music from audio files instead, to avoid the hassle of inserting CDs. To
-use ripped audio files, create a file named `playlist.txt` in the game
-directory, and enter the paths to your tracks, one per line. For example:

+The first line is not used because the first track on a game CD is typically a
+data track.

-### Unicode translation support
+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:

-The original System 3.x only supported Shift_JIS (a Japanese character
-encoding), but xsystem35 supports Unicode and is able to run games translated
-into languages other than Japanese and English.
+```
+SDL_SOUNDFONTS=/usr/share/soundfonts/GeneralUser.sf2 xsystem35
+```

-See [xsys35c](https://github.com/kichikuou/xsys35c)'s document for how to
-build a game with Unicode mode.
+### 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.

+## Usage
 ### 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.
+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 will be displayed. Since no games
+   have been installed yet, only the "Install from ZIP" button will be visible.
+   Tap it.
+3. Select the ZIP file you created in step 1.
+4. The game will start. To simulate a right-click, tap the black bars on either
+   the left or right, or top or bottom of the screen.

 ### 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:
+- 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 end with a number
+  will be 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)
+  - `rance4_03.wav` (Note: The filename shouldn't be `rance403.wav`, as 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.
+Note: This ZIP format is also compatible with
+[Kichikuou on Web](http://kichikuou.github.io/web/).

 ### 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.
+- 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 ZIPs containing Shift-JIS file names. This is the case with some ZIPs distributed on [retroc.net](http://retropc.net/alice/). If you get the error "This type of ZIP is not supported.", unzip the ZIP file on your PC and re-archive it with a modern ZIP creation software.

-                  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。  
-
-
-5. コマンドラインオプション
-
-  -h             : ヘルプを表示します。
-
-  -gamefile file : ゲームリソースファイルを file から読み込みます。

-
-  -fullscreen    : フルスクリーンでゲームを実行します。
-                   SDL 有効時には Widget にフォーカスが当たらないため Popup
-                   menu 等が使用できません。
-
-  -antialias     : 常に文字にアンチエリアスをかけます。
-
-  -noantialias   : 常に文字にアンチエリアスをかけません。シナリオ上でアンチ

-                   にしたい場合に指定します。
-
-
-6. その他情報
-
- 6.a. SYSV IPC
-
-    カーネルに SYSV IPC (SharedMemory/MessageQueue/Semaphore)の機能が
-  組み込まれている必要があります。
-
- 6.b. SharedMemoryの大きさについて
-
-   カーネルのSharedMemoryの大きさが十分大きい場合、MIT-SHMを利用して画面を
- 高速に描画する事が出来ます。起動時にエラーが出る場合、カーネルパラメータを
- 変更してみて下さい。(BSD 系はデフォルトの SharedMemory の大きさが小さい
- ようです)
-
- 6.b.1. FreeBSDの場合 /usr/src/sys/i386/conf/LINT 中の
-
-   options         SHMALL=1025
-   options         "SHMMAX=(SHMMAXPGS*PAGE_SIZE+1)"
-   options         SHMMAXPGS=1025
-   options         SHMMIN=2
-   options         SHMMNI=33
-   options         SHMSEG=9
-  「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。
-
-

-
-   プログラムの著作権は作者(chikama)に属しますが、ソースコードはGPLに基づいて
- 再配付できます。
- (一部のソースコードは私以外に著作権があります。詳しくは、ソースコードを御覧
-  下さい)
-
-   ゲーム内で使われてるカーソルフォントの一部をqvwm(Windows95そっくりのWindow
- Manager)からいただきました。

-
- 
-1. MIDIについて
-   
-   xsystem35 では MIDI の演奏に外部プレーヤーを使う方法と、サウンドカードの
- MIDI port を介して接続した外部 MIDI 機器を /dev/midi 経由で制御する方法、
- さらに、synthesizer device を OSS sequencer (/dev/sequencer) 経由で制御する
- 方法の３種類が選択できます。
-
- a) 外部プレーヤーを使う方法
-
-   1) xsystem35 側の準備
-        xsystem35 の configure 実行時に --enable-midi=extp を付けてコンパイル
-      しておきます。
-
-   2) プレイヤーの準備
-        TiMidity や playmidi など、お好みのプレーヤーをお使いください。
-      プレイヤーへはあらかじめパスを通しておき、~/.xsys35rc にプレイヤーと
-      プレイヤーへの引数を記述します。
-  
-       (例) TiMidity を esd 経由で出力する場合
-       midi_player: timidity -A 100 -s 44100 -Oe
-
-   2a) xsystem35へのリダイレクト (オプション)
-        TiMidity を使っている場合、TiMidity の PCM 出力を xsystem35 へとリダ
-      イレクトして xsystem35 側で管理しているPCM デバイスに流す事が出来ます。
-      ~/.xsys35rc の MIDI プレーヤーの設定の際に先頭に '-' をつけて下さい。
-
-      (例)
-       midi_player: -timidity -A 100 -s 44100 -Or -o-
-
-       この場合 timidity の出力は 44.1kHz, Stereo, 16bit 固定です。
-
-   3) 制限事項
-        外部プレイヤーを 使用する場合、MIDIファイルに埋め込まれた system35 用の
-      制御コマンドを実行することができず、リピート再生、ジャンプ再生などが出来
-      ません。このため、ゲームの進行に支障が出ることがあります。
-
-
- b) 外部 MIDI 音源を /dev/midi 経由で制御する方法
-
-   1) xsystem35 側の準備
-        xsystem35 の configure 実行時に --enable-midi=raw を付けてコンパイル
-      しておきます。
-
-   2) 外部 MIDI 音源の準備
-        外部 MIDI 音源(SC-88など)をサウンドカード の MIDI port を介して接続
-      します。このポートは /dev/midi デバイスを介して制御できる必要があります。
-      ALSA OSS Emulation 上で SB-Live の MIDI 端子に接続した SC-88 での動作を
-      確認しています。
-
- c) Synthesizer 音源を /dev/sequencer 経由で制御する方法
-
-   1) xsystem35 側の準備
-        xsystem35 の configure 実行時に --enable-midi=seq を付けてコンパイル
-      しておきます。
-   
-   2) Synthesizer 音源の準備
-        外部 MIDI 機器を接続するか、サウンドカード上に soundfont を load するか
-      TiMidity を ALSA sequencer server として常駐させておいてください。
- 
-      TiMidity を ALSA sequencer server にするには、コンパイル時にその機能を
-      有効にしておき、timidity -iA で常駐させます。
-
- d) オプション一覧
-
-      MIDI 出力に関する、 .xsys35rc の設定項目(A)とコマンドラインオプション(B)
-   をまとめます。
-
-   1) MIDI プレイヤーの設定
-        (A) ----> midi_player:
-        (B) ----> -midiplayer
-
-   2) MIDI デバイスファイルの設定 (default: /dev/midi or /dev/sequencer)
-        (A) ----> midi_device:
-        (B) ----> -devmidi
-

-
-
-4. PCM & MIDI(timidity) & CD-ROM(MP3) を１枚のサウンドカードで同時に使う方法
-   (special thanks to Fumihiko Murata)
-
-   サウンドカードを選ばない方法としては esd を使うことです。esd は対応した複数
- のプログラムの音の出力を合成してサウンドカードに出力するプログラムです。
- xsystem35/timidity/mp3 player を esd 対応にコンパイルすることで合成が可能
- です。
-
-   また、Trident 4DWave DX/NX、SoundBlaster Live/ YAMAHA YMF724以降 などのサウ
- ンドカードは PCM チャンネルを複数持っていて、対応のサウンドドライバーがあれば
- PCMとMIDI(SoftwareMIDI)とMP3 を同時に鳴らすことが出来ます。たとえば 
- SoundBlaster Live + ALSA では
-
- $ cat /proc/asound/pcm 
- 00-00: emu10k1 : EMU10K1 : playback 32 : capture 1
- 00-01: emu10k1 mic : EMU10K1 MIC : capture 1
- 00-02: emu10k1 efx : EMU10K1 EFX : capture 1
-
- のように PCM を 32 チャンネル持っていることが分かります。これは OSS でいうと
- ころの /dev/dspN に最大 32 の PCM がぶら下がっているように見え、同時に 32 回
- /dev/dspN を開くことが出来ます。
-
- また Trident 4DWave DX/NX + ALSA では全部で64chあり、最大で32chを PCM playback
- に割り当てる事ができます。最大チャンネルはモジュールロード時に 設定され、設定
- 数を使いきるまで同時に /dev/dspN を開く事ができます。
-
- 残りの 32ch は MIDI 用に設けられていて、PCM と MIDI の２つのバンクに分ける事
- ができます。個々のチャンネルには PCM front volume がありますが、２つのバンク
- をそれぞれ統括する Wave/Music Volume があり さらにそれらを合わせる PCM volume
- があります。(最後に Master Volume)
-
-  図にすると次のようになります。
-
-  PCM Volume + - Wave Volume  + - front volume- PCM Playback 0
-             |                + -  ..         - PCM Playback 1
-             |                :
-             |                + -  ..         - PCM Playback 31
-             |
-             + - Music Volume + -  ..         - PCM Playback 32
-                              :
-                              + -  ..         - PCM Playback 63
-
-
-   ES1370/1371 でも PCM 用 と MIDI 用に 2 チャンネルの PCM 出力があります。
- ALSA では 
- 
- $ cat /proc/asound/pcm 
- 00-00: ES1371/1 : ES1371 DAC2/ADC : playback 1 : capture 1
- 00-01: ES1371/2 : ES1371 DAC1 : playback 1
- 
- のように 0:0 と 0:1 のデバイスが再生用として使う事が出来ます。timidity 用に
- 0:1 のデバイスを使うと良いでしょう。OSS では /dev/dsp0 と /dev/dsp1 に割り当
- てられ、 /dev/dsp1 を timidity で使います。
-
- またその他のカードでも多チャンネル出力を持っているものもありますので、
- ドライバーのドキュメントを御覧下さい。
-
-
-(2003.1.23 追記)
-  追記を書いている時点で手に入りやすい多チャンネルPCM出力をもつ音源カード
-  としては SoundBlaster Live と YMF7xx くらいでしょうか。

+
+== Name
+
+xsystem35 - play System 3.x games
+
+== SYNOPSIS
+
+*xsystem35* [_OPTION_]...
+
+== DESCRIPTION
+
+This man page describes *xsystem35-sdl2*, a multi-platform port of the
+AliceSoft's System3.5/3.6/3.8/3.9 game engine derived from the original
+*xsystem35*.
+
+`xsystem35` reads the game resource file from the path specified by the
+`-gamefile` option, or from `xsystem35.gr` in the current directory if the
+option is not specified. If the game resource file is not found, `xsystem35`
+finds System 3.x game files (*.ALD) from the current directory.
+
+== OPTIONS
+
+*-gamefile* _file_::
+  Load game resouce file from _file_. See <<FILES>> section for details.
+
+*-game* _game_::
+  Enables game-specific hacks. Usually auto-detected, but must be specified for
+  games with modified / translated titles. Possible values are: `toushin2`,
+  `rance3_eng`, `rance4_eng`, `rance4_v2`, `persiom`, `agake`.
+
+*-savedir* _dir_::
+  Directory to save game state files. If _dir_ begins with '~', it is expanded
+  to the user's home directory (`$HOME`).
+
+*-saveformat* _fmt_::
+  The format when writing save files. Possible values are: `xsystem35`,
+  `system36`, `system39` (default).
+
+*-texthook* _mode_::
+  Set the text hook mode. Possible values are: `none` (default), `print` (print
+  text to console), `copy` (copy text to clipboard).
+
+*-texthook_suppress* _list_::
+  Suppress text hook on specified scenario pages. _list_ is a comma-separated
+  list of page numbers. Used to suppress system messages, etc.
+
+*-renderer* _name_::
+  Use the SDL rendering driver named _name_.
+
+*-playlist* _file_::
+  Load the CD playlist from _file_. The playlist is a text file with one
+  filename per line, in the order of CD tracks. See <<FILES>> section for details.
+
+*-Me*::
+  Use SDL_mixer for MIDI playback.
+
+**-Mp**_device_number_::
+  Use ALSA (via PortMidi) for MIDI playback.
+
+*-M0*::
+  Disable MIDI playback.
+
+*-devjoy* _device_index_::
+  Use the joystick device with the given index.
+
+*-ttfont_mincho* _file_::
+  Use the given TrueType or OpenType font file for mincho (serif) text.
+
+*-ttfont_gothic* _file_::
+  Use the given TrueType or OpenType font file for gothic (sans-serif) text.
+
+*-debuglv* _level_::
+  Set the debug level to _level_. The higher the level, the more verbose
+  the debug output.
+
+*-debug*::
+  Start with the debugger enabled.
+
+*-noantialias*::
+  Disable text antialiasing.
+
+*-fullscreen*::
+  Start in fullscreen mode.
+
+*-integerscale*::
+  Use integer scaling for the window.
+
+*-noimagecursor*::
+  Disable custom mouse cursor images.
+
+*-version*::
+  Print the version number and exit.
+
+*-h, --help*::
+    Print a help message and exit.
+
+== FILES
+
+*.xsys35rc*::
+  `xsystem35` reads its configuration from `${HOME}/.xsys35rc` and `.xsys35rc`
+  in the game directory. The latter takes precedence over the former, so you
+  can put general settings in `${HOME}/.xsys35rc` and game-specific settings in
+  `.xsys35rc` in the game directory. Options specified on the command line
+  override both. See xsys35rc.sample for the format of the configuration file.
+
+*playlist.txt*::
+  `xsystem35` does not support playing BGM directly from a CD. Instead, it
+  supports playing BGM from audio files on your filesystem. `xsystem35` reads
+  the playlist from a file specified by the `-playlist` option, or from
+  `playlist.txt` in the game directory. The first line is the path to the audio
+  file for track 1, the second line is the path to the audio file for track 2,
+  and so on. The first line is usually empty, because track 1 is not an audio
+  track but a data track.
+
+*xsystem35.gr*::
+  Game resource file which lists the locations of various files needed to run
+  a game. This is optional; `xsystem35` can automatically find the files it
+  needs when run inside a game directory. See
+  xref:xsystem35.gr.adoc[*xsystem35.gr(5)*] for the format of the game resource
+  file.
+
+== KEYBOARD SHORTCUTS
+
+System 3.x games basically only use the UP, DOWN, LEFT, RIGHT, SPACE, RET, ESC,
+and TAB keys (some games use other keys). `xsystem35` uses the following
+special key assignments:
+
+*F1*::
+  Toggle message skip mode.
+
+*F4*::
+  Toggle fullscreen mode.
+
+Also, in some platforms, the middle mouse button opens the menu.
+
+== HISTORY
+
+*xsystem35* was originally developed by Masaki Chikama (Wren)
+<masaki-c@is.aist-nara.ac.jp> between 1998 and 2006. The project was later
+forked by Kichikuou <KichikuouChrome@gmail.com> as *xsystem35-sdl2* and ported
+to SDL2.

+
+== Name
+
+xsystem35.gr - game resource file for xsystem35
+
+== DESCRIPTION
+
+Game resource file is a plain text file that defines the locations of the
+various game data files for xsystem35. This file is only needed if you want to
+place game data files in a location other than the current directory.
+
+The path to the game resource file is specified with the `-gamefile` option of
+xref:xsystem35.adoc[*xsystem35(6)*]. If it is not specified, xsystem35 reads
+`xsystem35.gr` in the current directory.
+
+Each line of the file specifies a single data file and follows the format:
+
+_keyword_ _path-to-data_
+
+If multiple files of the same type exist, suffixes `A`, `B`, `C`... are
+appended to the _keyword_.
+
+Comments can be added by starting the line with `#`. Blank lines are ignored.
+
+== KEYWORDS
+
+*Scenario*::
+  Scenario files (`*S?.ALD`).
+
+*Graphics*::
+  Graphic files (`*G?.ALD`).
+
+*Wave*::
+  PCM data files (`*W?.ALD`).
+
+*Midi*::
+  MIDI data files (`*M?.ALD`).
+
+*Data*::
