Use

Basic Usage

Create a ZIP file containing all the game files and BGM files (see below for details), and transfer it to your device.
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.
Select the ZIP file you created in 1.
The game starts. To simulate right-click, tap the black bars on the left/right or top/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:
- 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 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.

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. 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.
