DIG DUG
• At power-up, press and hold SELECT, and then press and hold RESET. You’ll get a completely empty playfield (picture #1). If you do this during a game, the screen will show exactly how everything was when you did the trick. This trick will cause the title screen to constantly stay on - the demo mode will not appear.
• On a game set to normal, there are basically 12 different rounds, after which they repeat. They are in sets of 4 rounds each, with the top soil layer colors being yellow, light green, and pink. This holds true until you pass round 126 (see bug below).
• The maximum number of lives you can have stored up is 7. {Gordon Taylor}
• BUG: At power-up, occasionally the game will be set to the Teddy bear level, instead of normal. This doesn't seem to happen with the Harmony cart or with emulators.
• BUG: The first time you press SELECT when the title screen is on, it will ‘reset’ the screen (but not change the variation).
• BUG: If you press SELECT and leave the game idle, it won’t go into the attract mode.
• BUG: The manual states you start with 5 lives, and can earn another 5 (at 20k, 50k, 100k, 150k, and 200k), but none after that; however, you earn a free life if you roll the score (at 1 million), and the same point values for free guys will still work.
• BUG: If you stand in the lower-left corner (at the very bottom, and no more than 2 body-widths away from the left edge – picture #2) as the last enemy escapes, you’ll be killed! If you have any reserve lives left, the enemy will likely reappear somewhere other than in a tunnel (ex. in solid dirt or on top of a rock!). Another side-effect of this bug affects the continue feature – you’ll start the new game several rounds ahead of where you left off.
• BUG: Although the manual says you can’t, you can pump through a narrow column of soil if you’re very close to it.
• BUG: A rare glitch may appear after rolling the score in which the ghost of a Fygar will suddenly appear somewhere.
• BUG: When the last enemy is a Fygar and it’s a ghost, the bottom-corner pixels of the sprite are shifted over to the right (picture #3).
• BUG: On a game set to normal, the action will speed up when certain rounds are reached, and actually decrease later in the game!
• BUG: On a game set to normal, there’s technically only 126 rounds, after which you’ll see rounds with strange layouts and sometimes only 1 or no rocks (so you can't always get the bonus veggie points - see video). It’s unknown if the game ever gets back to the original layouts. {Scott Stilphen}
