beatmania DA!!

beatmania DA!!
Developers: Oracion, Prime Systems Publisher: Konami Platforms: Windows, Mac OS Classic Released in JP: February 17, 2000 This game has unused text. This game has hidden bonus content.

Basically, beatmania, but transformed into a typing practice game. Apparently, the idea went well, and it spawned two sequels.

Unused Text

Each of the game's .bmd files, used for the chart data, have unused genre, song title and artist labels. All of these start from offset 0x20, save for Study\Key\Key.bmd, whose unused labels start at the file's very beginning. Most of the artist labels likely refer to Shintaro Sasaki, as he was in charge of "extending" most of the songs for the game.

Easter Egg

Clicking the Credits option while holding the keys B, M and D reveals a silly screen featuring a dancing character, with the text "びーとまにあ どうわっ!!" (roughly "beatmania DA!!") above. Clicking this mascot character briefly shows an edited image of DJ KONAMI with an unknown employee's head, as the text and sound "Typin' groooove!!" also appear.
