Liquid Kids is another cute platforming game from Taito. This one stars a water-bombing chap named Hipopo who's actually a platypus, not a hippo. Haven't been this confused since Donkey Kong.

Kumagaya Easter Egg

Taito Kumagaya Laboratory developed this game; their logo is hidden in the attract mode. To see it, wait for a demo to start playing, then press 1P Button 1 20 times.

Stage Select

This game uses the Taito Code:

  • Hold the Service Coin button until a "SERVICE SWITCH ERROR" message pops up on the screen.
  • Then, press 1P Start (x3), Service Coin, 1P Start.

Press 1P Left/Right to select the round, then press 1P Start to start a new game.

Debug Features

To use any of the debug menus below, you'll have to put this code in MAME's liquidk.xml (World), liquidku.xml (US), or mizubaku.xml (JP) cheat files to bypass this game's built-in ROM check:

  <cheat desc="Skip ROM Check">
    <script state="run">
    <script state="off">

Round Editor

Place the following code in liquid.xml / liquidku.xml / mizubaku.xml. Then, start the game in Service Mode and press 2P Start on the color bars screen to access a round editor.

  <cheat desc="Map Editor">
    <script state="run">
    <script state="off">

The first screen lets the user specify how big the testing round will be. XByte ranges from 0028 to 0100, and YByte ranges from 0020 to 0280.

After that, the user will be taken to the main round editor.
