+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

+languages other than Japanese and English.
+

+[xsys35c](https://github.com/kichikuou/xsys35c) documentation.

 ### 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. To simulate right-click, tap the black bars on the left/right or top/bottom of the screen.

+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.

 ## 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.

kichikuou	f247495578	Breaking change: Fix ShArray.ChangeSecretArray This breaks save file compatibility for Daiakuji and Kaeru nyo Kuni nyo Alice. Due to an incorrect encryption code in ShArray.ChangeSecretArray, save files were not interoperable with system3.9. (Even worse, this bug did not affect the checksum calculation and did not cause a "corrupt save file" error when a file saved with system3.9 was loaded with xsystem35 or vice versa.) Fixes #41.	2023-12-09 11:35:40 +09:00

kichikuou	4b15f45897	debugger: Add custom DAP messages for communicating palette changes This implements "xsystem35.palette" custom request and "xsystem35.paletteChanged" custom event. The "xsystem35.palette" request retrieves the color values of the AGS palette. interface PaletteRequest extends Request { command: 'xsystem35.palette'; } interface PaletteResponse extends Response { body: { /** * A number that increases each time the palette changes. / version: number; /* * 256 element array containing color values in 0xRRGGBB format. / palette: number[]; }; } The "xsystem35.paletteChanged" event indicates that the AGS palette has changed. interface PaletteChangedEvent extends Event { event: 'xsystem35.paletteChanged'; body: { /* * A number that increases each time the palette changes. */ version: number; }; } DAP clients can know if the received value is up to date by comparing the `version` values of paletteChanged and PaletteResponse.	2023-12-08 08:35:45 +09:00

kichikuou	f0ccfee40f	Update internal mouse coordinates even if cursor movement is disabled In TT2, keyboard/gamepad navigation is implemented by moving the mouse cursor using IZ command. It did not work in browsers where mouse cursor could not be moved or when mouse movement was disabled from the menu.

kichikuou	c694d2282c	Fix CX (sprite copy) in 24-bit color games with 16-bit CGs System3.x uses the following bit expansion when converting RGB565 to RGB888: RRRRR GGGGGG BBBBB => RRRRRRRR GGGGGGGG BBBBBBBB 12345 123456 12345 12345123 12345612 12345123 However, SDL's blit functions use a slightly different mapping, so sometimes expanded color did not match the color key specified in the CX command. To avoid this, convert to RGB888 by ourselves when drawing 16-bit CGs.	2023-06-19 17:18:17 +09:00

kichikuou	aec06f775a	Support the save format of original System3.x (except System3.5 v1) Now xsystem35 can load ASD files created by System3.5 (v2+) - System3.9. The format for saving can be configured with the -saveformat option.	2023-02-23 19:03:23 +09:00

kichikuou	b9f4c7c03a	Compatibility fix for Bx commands These commands accept 0-127 as valid window numbers, which were 1-128 before this change. To maintain savedata compatibility, window positions are saved in the order 1,...,127,0.	2023-02-18 21:45:39 +09:00
kichikuou	2d2c6aa373	Remove strvar_len The length limit of string variables was removed a long time ago, but it was recorded in save files. Now the first argument of MZ0 is completely ignored (as in System3.9).
