Description Separate each individual keyword with spaces. Surround a phrase with quotes to look for the exact phrase, or with / to use a PCRE regular expression. Prepend with - to exclude a keyword or phrase, with + to require a whole word or phrase, or with -+ to exclude a whole word or phrase. ? matches any character, * matches any amount of characters.

RAM Address	Length	Type	Description	Details
$7E0000	16 bytes	Misc.	Scratch RAM, is and can be used for a big number of purposes. The general purpose is temporarily preserving a value for later use in a routine. Of note is the following address, used in LM ASM hacks: $7E:0003 (16-bit) - Block number from LM Map16 editor. Also used in the custom Map16 tile change routine.
$7E0010	1 byte	Flag	If the value in it is not zero, run the actual game; otherwise, loop forever. It's set to a non-zero value during NMI, and it's set to zero after the game mode has been run, so that the game runs exactly once a frame - one NMI trigger per frame.
$7E0011	1 byte	Flag	Used to distinguish IRQ #1 from IRQ #2's code. (Inside the Morton/Ludwig/Roy room, where IRQ is used twice, although it can be used in other areas that run IRQ as well.) #$00 = IRQ #1; #$01 = IRQ #2.
$7E0012	1 byte	Graphics	Stripe image loader - value must be divisible by 3.	Valid Values
$7E0013	1 byte	Counter	"True" frame counter. Increments once per frame, except when the game is lagging. Note that $7E:0014 is better suited for most purposes.
$7E0014	1 byte	Counter	"Effective" frame counter. Stops when, for example, RAM addresses such as $7E:009D are not zero (lock sprite flag, usually indicates the player is dying, grabbing a powerup, or something similar). Inside sprite code, this address is often preferred over $7E:0013, especially in graphics routines, as graphics will not be updated when the player dies if this address is used as an index to the tilemap.
$7E0015	1 byte	I/O	Controller buttons currently held down. Format: byetUDLR. b = A or B; y = X or Y; e = select; t = Start; U = up; D = down; L = left, R = right.
$7E0016	1 byte	I/O	Controller buttons newly pressed this frame. Format: byetUDLR. b = B only; y = X or Y; e = select; t = Start; U = up; D = down; L = left, R = right.
$7E0017	1 byte	I/O	Controller buttons currently held down. Format: axlr----. a = A; x = X; l = L; r = R, - = null/unused.
$7E0018	1 byte	I/O	Controller buttons newly pressed this frame. Format: axlr----. a = A; x = X; l = L; r = R, - = null/unused.
$7E0019	1 byte	Player	Player powerup/status. #$00 = small; #$01 = big; #$02 = cape; #$03 = fire.
$7E001A	2 bytes	Hardware mirror	Layer 1 X position, current frame. Mirror of SNES register $210D.
$7E001C	2 bytes	Hardware mirror	Layer 1 Y position, current frame. Mirror of SNES register $210E.
$7E001E	2 bytes	Hardware mirror	Layer 2 X position, current frame. Mirror of SNES register $210F.
$7E0020	2 bytes	Hardware mirror	Layer 2 Y position, current frame. Mirror of SNES register $2110.
$7E0022	2 bytes	Hardware mirror	Layer 3 X position. Mirror of SNES register $2111.
$7E0024	2 bytes	Hardware mirror	Layer 3 Y position. Mirror of SNES register $2112.
$7E0026	2 bytes	Misc.	Depending on Layer 3 tides being activated or not, it's either: Not activated: Layer 2 X position minus Layer 1 X position. Activated: Layer 3 X position minus Layer 1 X position. Used for various things, among which interaction with multiple layers is included.
$7E0028	2 bytes	Misc.	Depending on Layer 3 tides being activated or not, it's either: Not activated: Layer 2 Y position minus Layer 1 Y position. Activated: Layer 3 Y position minus Layer 1 Y position. Used for various things, among which interaction with multiple layers is included.
$7E002A	2 bytes	Hardware mirror	Mode 7 Center X position. Mirror of SNES register $211F, + #$0080.
$7E002C	2 bytes	Hardware mirror	Mode 7 Center Y position. Mirror of SNES register $2120, + #$0080.
$7E002E	2 bytes	Hardware mirror	Mode 7 matrix parameter A. Mirror of SNES register $211B.
$7E0030	2 bytes	Hardware mirror	Mode 7 matrix parameter B. Mirror of SNES register $211C.
$7E0032	2 bytes	Hardware mirror	Mode 7 matrix parameter C. Mirror of SNES register $211D.
$7E0034	2 bytes	Hardware mirror	Mode 7 matrix parameter D. Mirror of SNES register $211E.
