BRINSTAR OBJECT /DOOR /ENEMY DATA

Notes: All data below is valid assuming that pointer tables to Brinstar rooms remain unchanged.

Room Format: The first byte of room data is the color attribute table to be used by that room, usually set to the dominant color pallette (00-03, one of the four pallettes used for room objects). Next follows any number of sets of three bytes which represent room objects and determine a particular object's color, location, and the object to be used. This continues until room data either encounters FD (End Object Data, Begin Door/Enemy Data) or FF (End Data For Entire Room). Enemys are represented by sets of three bytes following FD and these three bytes are indicative of sprite number assignment, enemy type, and location. (First digit of enemy type = easy/hard/boss enemy, second digit of enemy type = enemy to be used. First and second digits of location byte = separate X and Y coordinates.) Any doors in the room are represented by instances of "02 XY" immediately after FD and before enemy data: X determines whether the door is on the left (X="B") or right (X="A") side of the screen, and Y determines what type of door it is (Y="0" for 5-Missile/Red Door, Y="1" for Normal/Blue Door, Y="2" for 10-Missile/Yellow/Purple Door). Door/enemy data continues until FF is encountered signifying the end of a room's overall data. The following example room contains three objects, a red door on the left, a blue door on the right, and three enemies. Individual sections are highlighted for easy reference.

NORFAIR OBJECT /DOOR /ENEMY DATA

Notes: All data below is valid assuming that pointer tables to Norfair rooms remain unchanged.

Room Format: The first byte of room data is the color attribute table to be used by that room, usually set to the dominant color pallette (00-03, one of the four pallettes used for room objects). Next follows any number of sets of three bytes which represent room objects and determine a particular object's color, location, and the object to be used. This continues until room data either encounters FD (End Object Data, Begin Door/Enemy Data) or FF (End Data For Entire Room). Enemys are represented by sets of three bytes following FD and these three bytes are indicative of sprite number assignment, enemy type, and location. (First digit of enemy type = easy/hard/boss enemy, second digit of enemy type = enemy to be used. First and second digits of location byte = separate X and Y coordinates.) Any doors in the room are represented by instances of "02 XY" immediately after FD and before enemy data: X determines whether the door is on the left (X="B") or right (X="A") side of the screen, and Y determines what type of door it is (Y="0" for 5-Missile/Red Door, Y="1" for Normal/Blue Door, Y="2" for 10-Missile/Yellow/Purple Door). Door/enemy data continues until FF is encountered signifying the end of a room's overall data. The following example room contains three objects, a red door on the left, a blue door on the right, and three enemies. Individual sections are highlighted for easy reference.

TOURIAN OBJECT /DOOR /ENEMY DATA

Notes: All data below is valid assuming that pointer tables to Tourian rooms remain unchanged.

Room Format: The first byte of room data is the color attribute table to be used by that room, usually set to the dominant color pallette (00-03, one of the four pallettes used for room objects). Next follows any number of sets of three bytes which represent room objects and determine a particular object's color, location, and the object to be used. This continues until room data either encounters FD (End Object Data, Begin Door/Enemy Data) or FF (End Data For Entire Room). Enemys are represented by sets of three bytes following FD and these three bytes are indicative of sprite number assignment, enemy type, and location. (First digit of enemy type = easy/hard/boss enemy, second digit of enemy type = enemy to be used. First and second digits of location byte = separate X and Y coordinates.) Any doors in the room are represented by instances of "02 XY" immediately after FD and before enemy data: X determines whether the door is on the left (X="B") or right (X="A") side of the screen, and Y determines what type of door it is (Y="0" for 5-Missile/Red Door, Y="1" for Normal/Blue Door, Y="2" for 10-Missile/Yellow/Purple Door). Door/enemy data continues until FF is encountered signifying the end of a room's overall data. The following example room contains three objects, a red door on the left, a blue door on the right, and three enemies. Individual sections are highlighted for easy reference.

KRAID OBJECT /DOOR /ENEMY DATA

Notes: All data below is valid assuming that pointer tables to Kraid rooms remain unchanged, HOWEVER(!)...the Kraid pointer table that would normally point to Room 11 is actually pointing to Room 12. Therefore, using either Room 11 or Room 12 in Metroid's map data area will always cause Room 12 to appear at that location. Also, selecting both Room 11 and Room 12 within MetEdit causes Room 12 to be available for editing and use. Changing ROM address 12207 from a value of 47 to a value of 18 via a hex editor will correct this and make Room 12 seperately selectable withing the game's map data area, and will also make that room available for editing and usage within MetEdit.

Room Format: The first byte of room data is the color attribute table to be used by that room, usually set to the dominant color pallette (00-03, one of the four pallettes used for room objects). Next follows any number of sets of three bytes which represent room objects and determine a particular object's color, location, and the object to be used. This continues until room data either encounters FD (End Object Data, Begin Door/Enemy Data) or FF (End Data For Entire Room). Enemys are represented by sets of three bytes following FD and these three bytes are indicative of sprite number assignment, enemy type, and location.

Any doors in the room are represented by instances of "02 XY" immediately after FD and before enemy data: X determines whether the door is on the left (X="B") or right (X="A") side of the screen, and Y determines what type of door it is (Y="0" for 5-Missile/Red Door, Y="1" for Normal/Blue Door, Y="2" for 10-Missile/Yellow/Purple Door).

RIDLEY OBJECT /DOOR /ENEMY DATA

Notes: All data below is valid assuming that pointer tables to Ridley rooms remain unchanged. There is no object /door /enemy data for Room 00 of Ridley within the Metroid ROM. The Ridley pointer table that would normally point to Room 00 is actually pointing to Room 01. Therefore, using either Room 00 or Room 01 in Metroid's map data area will always cause Room 01 to appear at that location. Also, selecting both Room 00 and Room 01 within MetEdit causes Room 01 to be available for editing and use. Using Ridley Room 00 in lieu of Ridley Room 01 in Metroid's map data area is not recommended, as Room 01's data is normally configured as an elevator shaft in all areas and using Room 00 could cause bankswitching problems when using elevators depending on the configuration of Room 00 in other areas. (i.e. A room that completely changes from an elevator shaft to something else.)

Room Format: The first byte of room data is the color attribute table to be used by that room, usually set to the dominant color pallette (00-03, one of the four pallettes used for room objects). Next follows any number of sets of three bytes which represent room objects and determine a particular object's color, location, and the object to be used. This continues until room data either encounters FD (End Object Data, Begin Door/Enemy Data) or FF (End Data For Entire Room). Enemys are represented by sets of three bytes following FD and these three bytes are indicative of sprite number assignment, enemy type, and location. (First digit of enemy type = easy/hard/boss enemy, second digit of enemy type = enemy to be used. First and second digits of location byte = separate X and Y coordinates.) Any doors in the room are represented by instances of "02 XY" immediately after FD and before enemy data: X determines whether the door is on the left (X="B") or right (X="A") side of the screen, and Y determines what type of door it is (Y="0" for 5-Missile/Red Door, Y="1" for Normal/Blue Door, Y="2" for 10-Missile/Yellow/Purple Door).

The following example room contains three objects, a red door on the left, a blue door on the right, and three enemies. Individual sections are highlighted for easy reference.
