the ROM chips. The problem code allowed a player to do unintended things when ending their score in certain two-digit combinations. According to Joystik magazine, which detailed these combinations, the most useful were the ones that earned the player 40 free credits (06, 11, 12, 16, 17, 18) and the "jump to green" trick (46). Another useful combination mentioned was 05 which allowed the player to play the game in the attract mode. In this scenario pausing at one the combinations would cause the effect to take place immediately without losing the balance of the player's lives.
