Majokko Daisakusen

Release Date: 1999
English Title: Little Witching Mischiefs

It was released from Bandai for the Playstation, and in the game you can play as 38 characters from 7 mahou shoujo classic series: Lunlun, Cutey Honey, Meg, Lalabelle, Chappy, Sally, and Akko-chan.

The following is translated by Ian Miller, who gets a huge thank you. This is from the back cover of the game:

"Those witch girls (Majokko) have returned!

The mysterious girl who requests for help in the dream... The "witch girls" ("Majokko") who drive away accidents in the human world looked at the dream of the same girl. Confused, is it fate? Now the witch girls (Majokko) combine their strength to confront the new approaching evil."

In addition, that same year the CD Majokko Daisakusen - Special Song Collection was released. It included songs and music from the game and series featured. The two products were meant to tie-in together. (Information for CD found at CDJapan)
