Marimba Tengoku is a xylophone simulation rhythm game. It plays and looks similarly to Konami's own pop'n music series, having same-colored buttons, as well as a vibrant character cast.

Test Mode#

When the Konami logo is displayed, press the following keys in order:

  1. Press White or Yellow two times.
  2. Press Red or Blue two times.
  3. Press White or Green three times.

If the input is successful, the player will warp to a test mode. The "AUTO" option goes through all of the tests in order, which are as follows:

  • SWITCH TEST - Tests the game's inputs. The buttons must be pressed in order, from left to right.
  • POWER TEST - Appears to be a battery test of sorts.
  • VIDEO TEST - A display test.
  • AUDIO TEST - Plays a sine wave sound in the left, right, and then both channels.
  • EEPROM TEST - Appears to write something to the flash memory. Doesn't function in emulation.
  • ROM TEST - A ROM checksum test.
