TEST MODE:
  • Press CTRL + F3 for Test-Mode.
NOTE:
  • Clone Mr. Du! (mrdu): In this bootleg, diamonds give an absurd number of credits (99? 256? The game only displays 9; I gave up counting). However, diamonds appear very seldomly when compared to the parent, regardless of dipswitch setting. I can confirm from experience that this is the proper behavior for this ROM set. Needless to say, getting a diamond in this game was a real windfall when I was a kid :o) -The Dog
Bugs:
  • "Mr Do" (Taito) side-by-side test. Gary Walton (ID 01025)
WIP:
  • 0.129: Aaron Giles corrected Mr. Do! clocks, video parameters and merged memory maps. MooglyGuy added savestate support to all Mr. Do! games.
  • 0.125u5: Nicola Salmoria fixed colortable creation in Mr. Do! driver. Fixed diode voltage drop value which caused apples to be orange instead of red-orange. The title screen now perfectly matches http://www.flickr.com/photos/arecee/2384126902/sizes/l/ including the logo outline.
  • 0.123u2: Changed palettesize to 320 colors.
  • 0.114u3: Replaced SN76496 sound with SN76489.
  • 0.114u1: Justin Szczap added DIP locations to Mr. Do.
  • 0.59: Changed description of clone 'Mr. Do! (Yukidaruma)' to 'Mr. Do! (prototype)'.
  • 2nd February 2002: Mike Coates fixed scrolling in Mr. Do while flip screen is active.
  • 0.37b10: Nicola Salmoria improved colors in Mr. Do!. Changed VSync to 61.166569 Hz.
  • 0.37b7: Added prom ($60 - timing).
  • 0.36b10: Changed palettesize from 257 to 256 colors.
  • 18th November 2000: Nicola Salmoria fixed a stupid bug in Mr. Do! color PROM decoding.
  • 11th February 1999: Mirko Buffoni has made the interpolation stuff even better. Exed Exes example is about doubling with 50% transparent scanlines (left side), and Mr. Do! example is about doubling with linear interpolation (both sides) and 50% transparent scanlines (left side). All these things are of course off by default.
  • 6th February 1999: Mirko Buffoni has made interpolation routines for MAME. You'll need a powerful machine for this: (it's like ZSNES).
  • 0.34b8: Gareth Hall added Mr. Do! (bugfixed), version with a fixed bug which would allow to get 255 lives. Lee Taylor added Yankee DO! (Two Bit Score)(bootleg 1982 with different graphics).
  • 0.34b6: Nicola Salmoria added clone Mr. Do! (Yukidaruma) (bootleg 1982 - with different graphics and music).
  • 0.30: Lee Taylor added clone Mr. Du! (bootleg 1982). Tatsuyuki Satoh and Nicola Salmoria cleaned up the SN76496 emulation, now it is similar to the 8910 one and all games use Tatsuyuki's code. This affects several games, most notably the Mr. Do! series.
  • 0.18: Added Mr. Do! (Universal). Renamed (mrdo) to (mrdot).
  • 0.04: Optimizations in drawgfx(), Mr. Do!'s title screen and intermissions now run faster, Crazy Climber and Crazy Kong benefit as well.
  • 0.02: Nicola Salmoria added Mr. Do! (Taito 1982). Thanks to Paul Swan for the information on Mr.Do! colors. The noise generator is not emulated yet, but Nicola think Mr. Do! doesn't use it anyway.

history Mr. Do! (c) 1983 Universal.


Mr. Do! is a colourful and addictive maze game in which the player takes on the role of the eponymous Mr. Do, a circus clown who must clear each level of either cherries or monsters. The game's single screen levels are made up of tunnels surrounded by a colourful, soil-like substance. This soil can be dug through to create new tunnels, allowing Mr. Do to escape his enemies and to reach the many cherries that litter the levels. A number of apples are also scattered around each level, and Mr. Do can push them along tunnels (to block and/or kill monsters) or can tunnel beneath them to drop them onto the heads of any pursuing enemies. Mr. Do himself can also be killed by a falling apple.


Mr. Do is armed with a 'Powerball' that can be fired down a tunnel, it will then bounce around the tunnels until it either returns to Mr. Do, or comes into contact with, and kills, one of the level's monsters. The Powerball will only return once Mr. Do has tunneled under more soil. As each level progresses, the monsters themselves start to dig tunnels of their own in their pursuit of Mr. Do. Monsters can also push the apples.


Each screen has a doorway through which the monsters enter the level. Once all of the monsters have appeared, the doorway will turn into a 'prize', (ice cream, biscuits, etc.). If the player collects the prize, the 'Alphamonster' and his four henchmen will appear. The Alphamonster may be in the EXTRA box at the top of the screen or be moving around the screen. The Alphamonster and his henchmen cannot be easily crushed under apples because they tend to eat them. They can be killed individually with the Powerball or by killing the Alphamonster itself, at which point any remaining henchmen will turn into apples.


After every three levels, there is a brief intermission in which a tune is played and a large, animated Mr. Do appears, together with some of the game's monsters. The time to complete each level and the preferred method (monsters, cherries, EXTRA or Diamond) is shown. The paths in the first level resemble a 'D', after this each level's tunnels resemble a digit, ('2', '3', '4' etc.) up to '0' for level 10.


A level can be completed any one of several different ways : either by collecting all of the on-screen cherries; by killing all of the monsters, by completing the EXTRA box, or by collecting the diamond. The latter appears only very occasionally ('Special' awards an extra credit).

- TRIVIA -


Mr Do! was also licensed to Taito.


Inspired by "Dig Dug". The first in a series of four Mr. Do! games, Mr Do! was one of video-gaming's biggest arcade successes. Unfortunately for Universal, none of their other games could match it in commercial terms and the company disappeared in the video game crash of 1983-84.


Mr. Do is the game responsible for launching the kit game craze in the U.S. video game industry.


David Breckon holds the official record for this game with 26,030,050 points.


A bootleg of this game is known as "Mr. Lo!" and another is called "Mr. Du!".


There are several well-known hacks of Mr Do! which are as follows :

* Mr. DigDo! - graphics changed to make them look more like those of Namco's "Dig Dug".

* Mr. Jong - Changes the clown into an old Chinese man, the monsters into clowns and the apples into mahjong blocks.

* Yankee Do! - Changes the graphics to make them more American patriotic.


- UPDATES -


On the Prototype version (which is a Japanese hack) :

* You are a 'Yukidaruma' (a snowman) with green arms instead of the famous clown.

* You dig with a rake in your hands.

* There is a mean expression when you push an apple.

* The screen does not change colour when you grab cookies, cake, etc...


- SCORING -

- TIPS AND TRICKS -


* 255 Lives Tricks : It's possible to win 255 lives on the first screen, but only if an apple appears in the top two rows of the playfield.

1) Begin by digging a tunnel directly from the bottom of the screen to just below the apple, but leave enough dirt under it that it doesn't fall.

2) Next, kill all of the enemies but one, then lose all of your extra lives. As soon as you're on your last life, go right under the apple and wait.

3) Eventually, the remaining enemy will come after you. Allow the apple to drop, but, in the interval before you're squashed, kill the enemy with the powerball. If all has gone well, you'll be carried to the bottom of the screen, the music will go haywire for a moment, and you'll be awarded 255 extra lives.

4) Note that you should always lose a life before spelling 'EXTRA', or you'll roll back to zero lives, so, to be safe, immediately kill yourself at the start of level two.

5) IMPORTANT : This trick will only work with the Taito version of Mr. Do!.


* Here's A Neat Trick : You can divide the screen into a grid. The cheries, apples, and tunnel corners are all centered on a grid element. If you are being chased by the normal badguys (not ghosts) you can dig and stop between grid elements. The badguy will think it needs to turn into a digger to get you. While he's changing forms, you can escape.


* An alphamonster will appear after every 5,000 points.
