NES core
This movie(youtube,niconico) I uploaded was created with QuickNes.
It was converted to NesHawk by
ThunderAxe31.
I would like to thank you once again.
After this, it is a description similar to the previous one.
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.
