For those who do not know about this game

Dr. Mario is a simple puzzle game.
Dr. Mario periodically throws Megavitamins into the bottle.
Afterwards, the player can move and land them on Viruses, which spawn throughout the bottle.
By connecting a line of three or more halves of Megavitamins to a virus of the corresponding color, the Virus disappears.
Removing all viruses on the screen advances the player to the next level.
Completing level 20 is the ending.

Basic technique

  • There is no time difference by SPEED(MED/HI). LOW is slow because Mario's throwing action is long.
  • The Down key reacts only even frames.
  • The Left / Right key reacts in both even and odd frames.
  • If you press A, B and Left key at the same time, you will move to left two times.(However, it is limited to timing when it can rotate)

Layout and pill sequence

Layout and pill sequence is determined when level is selected.
It does not change after it is decided once.
This is determined by the number of frames since the start of the game.
This record resets the frame by soft reset on the way and selects the optimum placement.
(Soft reset maintains level information,but do not maintain number of frames. In this way, you can select an arrangement that can not be selected normally.)

Remove glitch

"Remove glitch" occurs when many viruses are deleted in one chain.
After "Remove glitch", it sometimes freeze.
Freeze may be canceled by pressing the controller button of player 2.
Regarding the necessary buttons, the internal numerical value of the cross key and the column number are likely to be related, but details are unknown.

When "Remove glitch" occurs, the behavior changes according to the direction in which the last virus removed.
If it removes vertically, all that one column will remove.
If it removes laterally, all removes from lower than that line.
After the laterally, it is now possible to delete all viruses by operating the 2p controller!

The root cause of "Remove glitch" is the occurrence of NMI due to high load.
The processing with the highest load is score addition.
The following is the score table.

virus Score
01 +100
02 +200
03 +400
04 +800
05 +1600
06 +3200
07 +3200
08 +3200
09 +3200
10 +3200
11 +3200
12 +1000
13 +300
14 +25600
15 +100
16 +200
17 +400
18 +25600
The score has increased at the 14th virus.
This is the reason why "Remove glitch" occurs in the 14th virus.
Besides erasing the 14th virus, even if you erase the 3rd ~ 10th virus simultaneously, "Remove glitch" will occur.

Please see below for details.(However, it is Japanese.)

ThunderAxe31: Judging.

ThunderAxe31: The usage of the reset button is allowed for this game, as the game keeps track of the last level beaten even after resetting. More explanations can be found in the judgment note of a previous submission for the same game. Like the previous movies, this movie does not select the subsequent levels manually, so the full-completion goal has been achieved legitimately here as well.

This movie is even more impressive than its predecessors, and the audience has been once again delighted. Accepting for Moons as an improvement over the current publication.
