Florida dmv look up driver s license number. A puzzle game similar to Tetris , Dr. Mario features Nintendo mascot Mario as a doctor. Play consists of dropping two-sided vitamin capsules into an eight-block-by-16-block playing field populated by viruses of three colors (red, yellow, and blue).
There are six types of capsules, differentiated by their color: red-red, yellow-yellow, blue-blue, red-blue, red-yellow, and blue-yellow. The player must rotate and position these capsules on top of and alongside the viruses and other capsules in an effort to eliminate the viruses. Both viruses and capsules are eliminated when four or more objects of corresponding color are placed in a row or column. A player completes a level by eliminating all viruses on the playing field. Conversely, the game will end if any capsules obstruct the bottle's narrow neck at the top row of the field. The game consists of 21 distinct levels, whose starting virus counts range from four at level 0 to 84 at levels 20 and higher. Above level 20, each level starts with 84 viruses. Levels do not increase in difficulty past level 20. Much like Tetris , the player may choose a level of difficulty to start, along with the game's speed and a selection of background music .
The Game Boy version of the game is nearly identical to its NES counterpart. In keeping with the technical limitations of the device, the game features a playfield measuring eight-blocks by 15-blocks and viruses of black, white, and gray.

Dr Mario is a classic action puzzle video game that was released back in 1990 for multiple gaming consoles including the Nintendo Entertainment System (NES). Unlike the traditional Mario gaming franchise, Dr. Mario features a falling block gameplay similar to the popular Tetris video game.
Two player gameplay in either version consists of two side-by-side playfields that can be level-adjusted according to the strength of each player. The first player to win three games wins the match. The objective is to be the first to clear the viruses or to block the opponent's field to the top. An added element is the ability to 'rain' down random blocks into the opponent's playfield by achieving double (triple, quadruple, etc.) combinations of eliminated lines on the same vitamin.

Dr. Mario is Nintendo's own little action puzzle game, where Mario throws pills into a jar to get rid of viruses.
Unused Demo
Present within the ROM is a second gameplay demo meant for when the player idles at the title screen, though the demo recorder in this case does much worse than the standard one.
Unused Code
There is code that was supposed to fill the top part of the game board. It was 'fixed' with a jr instruction.
Unused Level Configurations
For the virus placement algorithm, there are two tables filled with values that, when added together, do not surpass 0x66.
The index to these tables is the level selected. The base addresses are:
And the code that reads from these tables is at 0:3076.
These tables are side-by-side in the ROM, and each table is 31 (0x1F) entries, though only in Rev 1 (see below as to why). In code (located at 0:101C), the max level limit is 30 (0x1E).
Because there are only 20 selectable levels, it's a good guess that the developers probably didn't intend players to get too far past Level 20 (not helped by a bug related to the viruses that can softlock the game; see the Bugs page for more).
You can access this entry by changing the level selected byte (0xFFC3).
Dr Mario GameRevisional Differences![]()
Rev 1 added six more levels, with the game looping Level 30 repeatedly. The original release had 24 levels (and looped Level 24 repeatedly), with an unused 25th.
Rev 1 also removed a duplicate '2 player GAME' and '(c) Nintendo 1990' tile map.
The other changes made with Rev 1 consist of minor offset calculations and header updates.
