RAM Address	Length	Type	Description	Details
$7E0DAA	1 byte	I/O	Controller 1 button disable flags ($4219), one frame. If a bit is set here, that bit will be disabled in $16/$0DA6 (but not $15). Format: byetUDLR. b = B, y = Y, e = Select, t = Start, UDLR = Up/Down/Left/Right.
$7E0DAB	1 byte	I/O	Controller 2 button disable flags ($421B), one frame. If a bit is set here, that bit will be disabled in $16/$0DA7 (but not $15). Format: byetUDLR. b = B, y = Y, e = Select, t = Start, UDLR = Up/Down/Left/Right.
$7E0DAC	1 byte	I/O	Controller 1 button disable flags ($4218), one frame. If a bit is set here, that bit will be disabled in $18/$0DA8 (but not $17). Format: axlr----. a = A, x = X, l = L, r = R, 0 = null/unused.
$7E0DAD	1 byte	I/O	Controller 2 button disable flags ($421A), one frame. If a bit is set here, that bit will be disabled in $18/$0DA9 (but not $17). Format: axlr----. a = A, x = X, l = L, r = R, 0 = null/unused.
$7E0DAE	1 byte	Hardware mirror	Handles brightness and force blank. Format: f---bbbb. f = force blank flag, --- = unused bits, bbbb = brightness setting. Mirror of SNES register $2100.
$7E0DAF	1 byte	Misc.	Mosaic direction. #$00 = shrinking mosaic; #$01 = growing mosaic.
$7E0DB0	1 byte	Hardware mirror	Current mosaic pixel size on level load. Mirror of SNES register $2106, though bits 0 and 1 are always set ($2106 = $7E:0DB0 | #$03).
$7E0DB1	1 byte	Timer	Is used to keep a mode active. If the respective value is positive, the game mode doesn't change. This is primarily used in the fading routines (example: from overworld to level and vice versa).
$7E0DB2	1 byte	Flag	Two player game flag. #$00 = No; #$01 = Yes.
$7E0DB3	1 byte	Player	Which character is in play. #$00 = Mario; #$01 = Luigi. If you prefer Luigi to be #$04, use $7E:0DD6.
$7E0DB4	1 byte	Player	Mario's lives. Note that this is only used in two player games, you'll want $7E:0DBE in 99% of the cases.
$7E0DB5	1 byte	Player	Luigi's lives. Note that this is only used in two player games, you'll want $7E:0DBE in 99% of the cases.
$7E0DB6	1 byte	Player	Mario's coins. Note that this is only used in two player games, you'll want $7E:0DBF in 99% of the cases.
$7E0DB7	1 byte	Player	Luigi's coins. Note that this is only used in two player games, you'll want $7E:0DBF in 99% of the cases.
$7E0DB8	1 byte	Player	Mario's powerup/status. Note that this is only used in two player games, you'll want $7E:0019 in 99% of the cases.
$7E0DB9	1 byte	Player	Luigi's powerup/status. Note that this is only used in two player games, you'll want $7E:0019 in 99% of the cases.
$7E0DBA	1 byte	Yoshi	Mario's Yoshi color. #$04=yellow; #$06=blue; #$08=red; #$0A=green
$7E0DBB	1 byte	Yoshi	Luigi's Yoshi color. #$04=yellow; #$06=blue; #$08=red; #$0A=green
$7E0DBC	1 byte	Player	Item in Mario's item box. #$00 = None; #$01 = Mushroom; #$02 = Fire Flower; #$03 = Star; #$04 = Feather. Note that you'll want $7E:0DC2 in most cases.
$7E0DBD	1 byte	Player	Item in Luigi's item box. #$00 = None; #$01 = Mushroom; #$02 = Fire Flower; #$03 = Star; #$04 = Feather. Note that you'll want $7E:0DC2 in most cases.
$7E0DBE	1 byte	Player	Current player lives, minus one (#$04 here means that the player has 5 lives).
$7E0DBF	1 byte	Player	Current player coin count.
$7E0DC0	1 byte	Counter	Green star block coin counter. Starts at 30 at the beginning of a level, and decrements for each coin that is collected. Adjusts content of green star block when it hits zero. (A 1-Up mushroom comes out, instead of a spinning coin.)
$7E0DC1	1 byte	Yoshi	Player can carry Yoshi over levels flag. #$00 = can't carry over levels; #$01 = can carry over levels.
$7E0DC2	1 byte	Player	Item in current player's item box. #$00 = None; #$01 = Mushroom; #$02 = Fire Flower; #$03 = Star; #$04 = Feather.
$7E0DC3	4 bytes	Empty	Empty. Cleared on reset and titlescreen load. $7E:0DC3 is also cleared when selecting how many players to use, but this can be disabled with no known side effects by setting $00:9E48 to [80 01 EA].
$7E0DC7	2 bytes	Player	Overworld X position where Mario should be going to. Is used by overworld path tiles to indicate Mario's direction. Updated as soon as Mario starts moving - zero otherwise.
$7E0DC9	2 bytes	Player	Overworld Y position where Mario should be going to. Is used by overworld path tiles to indicate Mario's direction. Updated as soon as Mario starts moving - zero otherwise.
$7E0DCB	2 bytes	Player	Overworld X position where Luigi should be going to. Is used by overworld path tiles to indicate Luigi's direction. Updated as soon as Luigi starts moving - zero otherwise.
$7E0DCD	2 bytes	Player	Overworld Y position where Luigi should be going to. Is used by overworld path tiles to indicate Luigi's direction. Updated as soon as Luigi starts moving - zero otherwise.
$7E0DCF	2 bytes	Player	Player X speed on the overworld. Added with $7E:13D5, which does happen to be zero all the time.
$7E0DD1	2 bytes	Player	Player Y speed on the overworld. Added with $7E:13D7, which is zero most of the time.
$7E0DD3	1 byte	Overworld	Player direction. #$00 = up; #$02 = down; #$04 = left; #$06 = right.
$7E0DD4	1 byte	Should be 00	This address is effectively the high byte of $0DD3 on the overworld and should not be touched there, though in levels it is unused. It is also referenced once as the low byte of $0DD5, though its value isn't used there. Cleared on reset and titlescreen load, and when Mario starts walking on an overworld path.
$7E0DD5	1 byte	Misc.	Used to indicate how a level has been exited, and hence what events to activate on the overworld.	Valid Values
$7E0DD6	1 byte	Player	Which character is in play. Used on the overworld. The value of this address is actually $7E:0DB3 * 4. #$00 = Mario; #$04 = Luigi.
$7E0DD7	1 byte	Should be 00	An address that is expected to be #$00 throughout the entire game. $7E:0DD6 (current player) is sometimes used in 16bit mode, so using this address for different purposes is a bad idea.
$7E0DD8	1 byte	Flag	Used to tell if the game is currently switching between Mario and Luigi or not. #$00 = Not switching between Mario and Luigi. #$01 = Switching between Mario and Luigi, during the fade-out.
$7E0DD9	1 byte	Empty	Empty. Cleared on reset and titlescreen load.
$7E0DDA	1 byte	Misc.	Back-up of the music register. Gets its value from the level music table at $05:84DB. Bit 7 of this address is set when the player has a star powerup or presses a P-switch; when this is cleared again, the music ends. This address is also set to #$FF when the level ends, either by beating it or by dying. Bit 6 is similar but is used to not reupload all music. This is used when changing from the Mario start screen to the level game mode.
$7E0DDB	3 bytes	Empty	Empty. Cleared on reset and titlescreen load.
$7E0DDE	1 byte	Misc.	Which files to delete on the erase file screen. Format: xxxxx123. It is also used as an overworld sprite index.
$7E0DDF	1 byte	Sprites	Starting OAM index for overworld sprites. Appears to be used only by the cloud sprites.
$7E0DE0	5 bytes	Sprites	Used for the overworld cloud sprites. This table is used in such a way that clouds check each other's 16-bit Y positions. By doing this, they can maintain their speed, making it the same for all clouds on-screen.
$7E0DE5	16 bytes	Sprites	Overworld sprite number.	Valid Values
$7E0DF5	16 bytes	Sprites	Miscellaneous overworld sprite table.
$7E0E05	16 bytes	Sprites	Miscellaneous overworld sprite table.
$7E0E15	16 bytes	Sprites	Miscellaneous overworld sprite table.
$7E0E25	16 bytes	Sprites	Miscellaneous overworld sprite table.
$7E0E35	16 bytes	Sprites	Overworld sprite X position, low byte.
