Donkey Kong II: Jumpman Returns (hack, V1.1) - MAME machine

Arcade Video game published 18 years ago:

Donkey Kong II - Jumpman Returns © 2006 Unknown.

A hack of "Donkey Kong" which adds four new stages and changes the original four stages slightly.

New stages:

• Foundry stage: Jump over flaming pits, ride moving steel beams, and dodge shooting fireballs! Welcome to the Foundry!
• Refinery stage: Oil, gas, and a couple of safety valves? This has DANGER written all over it. Oh yeah, watch out for the fire, too.
• Incinerator stage: Multiple conveyors deliver trash (Cement Pies and Springs) to a burning pit. Beware! If Jumpman stops moving, he'll be headed down there, too!
• Mixer stage: Conveyors, falling Cement Pies, and the Mixer! Can you make it past?

The original four stages from "Donkey Kong" are also included, but have been changed in the following ways:

• Ramp stage: On later levels, once the first Beam reaches the oil can, three fireballs shoot out of the can and up the screen, landing on the 2nd, 4th, and 6th girders.
• Conveyor Belt stage: Jumpman must now navigate to the upper level where Pauline is, instead of the level where Donkey Kong is.
• Elevator stage: There are now three elevator shafts instead of two.
• Rivet stage: The player can no longer score points by jumping next to Donkey Kong. Also, the Firefox population slightly increases on later levels.

Upon completing the Rivet stage, Donkey Kong initially doesn't fall all the way down, but grabs hold of the top girder. Jumpman then jumps on his hands to make him fall. This is followed by a scene where the screen says CAPTURED ! and CONGRATULATIONS, with an oil can, Kong in a cage, and Jumpman and Pauline looking on.

TRIVIA
When the original "Donkey Kong" was first released in arcades in July 1981, Mario was originally called 'Jumpman', hence this hack's subtitle, "Jumpman Returns".

More differences from the original "Donkey Kong":
1) The score readouts show seven digits, instead of six.
2) If the game is set to free play, the player can switch between Donkey Kong II - Jumpman Returns and the original "Donkey Kong" (US version) by holding down both start buttons for five seconds.
3) The top five high scores and initials are remembered permanently.
4) True free play mode is available. The standard attract mode runs while in free play mode.
5) Sound can be turned on for the attract mode.
6) There are extensive power-up diagnostics.
7) There is an onscreen settings menu which allows easy changing of game settings and erasing of high scores.

There are a total of eight stages, presented in the following order:
25m - Foundry stage
50m - Ramp stage
75m - Refinery stage
100m - Conveyor Belt stage
125m - Incinerator stage
150m - Elevator stage
175m - Mixer stage
200m - Rivet stage

There are four intermissions which play after the 50m, 100m, and 150m stages:
1) Pauline is walking with her items, then Donkey Kong jumps out and Pauline runs away, dropping her umbrella, purse and hat.
2) Using a Cement Pie as a pillow and a Barrel to prop his feet up, Donkey Kong is sleeping. Jumpman then lights his foot on fire. Donkey Kong wakes up and jumps around. This intermission serves as an homage to Sega's "Congo Bongo".
3) Jumpman is sleeping on a girder, balanced with a cage. Donkey Kong, below, picks up an apple and then grits his teeth.
4) Jumpman chases Pauline across the screen, then they run towards each other and bump together. This bump causes Jumpman to bounce backwards a bit, but he recovers and runs right up next to Pauline.

SCORING
Jumping over Barrels, Beams, Fireballs, Cement Pies, or Firefoxes: 100 points

• Sometimes scoring can occur when objects are next to or behind the player when jumping (especially the Springs on the Elevator Stage).

On the Ramp Stage only:
Two items jumped: 300 points
Three or more items jumped: 500 points

• Due to a bug in the program, jumping three or more items displays onscreen 800 points but actually awards only 500 points.
• Sometimes jumping over one or more objects scores no points.

Destroying objects with the hammer:
Barrels: 300 points
Beams, Fireballs, Cement Pies, and Firefoxes: 300, 500 or 800 points

Picking up Pauline's purse, hat, or umbrella:
L-01: 300 points
L-02: 500 points
L-03 onward: 800 points

Removing a rivet: 100 points

On the Incinerator Stage only:
Picking up a heart: 100 pts.

When a stage is completed the player receives the points shown in the bonus box.
Starting bonus points:
L-01: 5,000 points
L-02: 6,000 points
L-03: 7,000 points
L-04 and up: 8,000 points

TIPS AND TRICKS
There is an easter egg on the new cut scene that plays after completing the Rivet Stage, which can be triggered by pressing UP on the joystick: something pokes its head out of the oil can, but only high enough to see its eyes. Above this is written PAPA ?
