Prototype Info

Level Select

The Game Genie code SKKLUKXT enables an input code to access a level select. On the screen to select the amount of players who will play (1 Player, 2 Players), enter the following code: Right, Left, Down, Up, A, B. If done correctly, you will hear a tone. Choose your character as normal and you can pick every level in the game, except for 6-3, curiously. Note that 6-3 can be selected, but it will not bring you there. The controls are as follows:

Hold B, then press Up or Down to change the world number. Hold A, then press Up or Down to change the stage number. Start leaves the screen and takes you to the desired level.

Sound Test

At the copyright screen, but before the title screen appears, press and hold Right + A + B + Start and wait. Instead of the title screen, a sound test mode will be triggered. If you don't want to wait, additionally hold the Select button.

Press Up / Down to select a music track, press A / B to start or stop playing.

Complete list of the tracks:

• "Get out from a Pocket"
• "Twist and Select"
• "Warlock Eyes"

Build Dates

At the end of the PRG ROM, there is a string with information on the game's compilation date and status:

MAST911001

Similar strings are found in many other Konami games.

"MAST" means it's the "master" version of the game, and the numbers are the compilation date. So, this version was finished on October 1, 1991. The date is the same in both versions of the game.
