Conquest of the Crystal Palace

Debug Mode
At the title screen hold B + Select for a short time, release the buttons and after a while press A + Select a couple of times (not holding it), untill a sound will confirm correct code entry. Normally, you can trigger this cheat with just one A + Select keypress, but the program skips the code test every 8 frames, so you can just miss it, if press exactly at that time. Press A + Select another couple of times to disable this cheat back. Begin game play, hold Select and press one of the following button combinations to activate the corresponding cheat function.
 * Right - Temporary invulnerability
 * Left - Extra gold
 * Up - Jumping Shoes
 * Down - Full life
 * Up + Right - Extra lives (up to 99)
 * Down + Left - Power-up weapon
 * Up + Left - Moon Mirror
 * Down + Right - Zap energy

Sound Test


At the title screen, hold A + B + Select for the Sound Test to appear. Press Up / Down to switch between music and sound, but since there is no cursor, the only way to know which one is highlighted is to press Left / Right to change the numbers.
