Disabled Debug Routines
All three Famicom games (the other two being Famicom Meijin Sen and Sted: Iseki Wakusei no Yabou) developed by Alpha Denshi contain the same debug routines to test game internals or engines.

Scrolling Engine Test
This game contains scrolling engine test routines only. Since this is just leftovers from the software library, there is no actual background data, but there is a proper ASCII font set up and the engine itself is working. Use the Game Genie code then reset the console. Now you can scroll background garbage in any direction by pressing the D-Pad buttons on the first controller, and with the A or B buttons you can play the test sounds. On the second controller press the A button to print the string "TEST0123456789TEST" to the background. There are two sprites at the center of the screen too; using the D-Pad on the second controller, you can move one of them around the other one.
