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 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.

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. 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.
