About voice cancellation:
Voice cancellation reduces the singer's voice by reducing the sound located in the center of the stereo-recorded song, not the effect of muting the singer's voice. Also, we do not recommend voice cancellation for songs recorded in monaural, as the entire song will be smaller. Voice cancellation of songs recorded in stereo, such as folk songs, songs of Japanese music such as Shigin, songs with few classical and musical instruments, songs of duet, songs with strong chorus and echo, songs where the voice of the singer is not located in the center, etc. May not be effective.

■ To change the settings

With Sega Saturn, you can change the date and time of the built-in clock, the display language of the multiplayer screen, and so on.

● Date and time settings:
On the date and time setting screen, select an item with the left and right direction buttons, and change it up and down. Select "Enter" and press the C button to change the date and time and return to the user setting screen.

The application can use the date and time set by the user, but it must not be changed. To change the date and time, you need to have the user set it on the date and time setting screen.

● Language setting:
You can select the display language of the multiplayer screen from the following 6 countries.
English, German, French, Spanish, Italian, Japanese

Multilingual applications must determine the default language from this custom language. In addition, if there is a function in the application to change the supported language by the user, it is necessary to change the setting by a predetermined method so that it will be reflected in the multiplayer language setting.

● Other settings / help window:
You can select "Show / Hide" the help window on the multiplayer screen.

Help window settings should not be referenced or modified by the application.

You can switch between stereo and monaural audio output for music CDs, CD + G, and CD + EG.

For monaural-enabled applications, the default audio output settings must be determined from this user-configured audio output setting. In addition, if the application has a function for the user to change the audio output setting, it is necessary to change the setting by a predetermined method so that it will be reflected in the multiplayer audio output setting.

● Other settings / sound effects:
You can select ON / OFF of the sound effect on the multiplayer screen.

Sound effect settings should not be referenced or changed by the application.
