WELP! Didnt want to make a thread, but no one replied in the help thread, soooo...

I'm trying to write ASM for sm64ds and i need the player to be able to perform an action when they press a certain button. All that was given in the asm patch template folder was the button press values for B (0x00F) and the the values for either L or R being pressed (0xF00), i need to know what the rest of the button pressed values are. Thanks in advance!

This is code from the NSMB Hacking Template, but I'm pretty sure that it's applicable to any DS game.
keys.cpp:
#include<nds.h>

static int keys, oldKeys, keysDw;
static bool first = true;

void myScanKeys()
{
first = false;
int keys = ~REG_KEYINPUT;
if(first) oldKeys = keys;
keysDw = keys & ~oldKeys;
oldKeys = keys;
}

int myKeysHeld()
{
return keys;
}
int myKeysDown()
{
return keysDw;
}
keys.h add to SM64DS.h:
//Custom key reading funcs.
void myScanKeys();
int myKeysHeld();
int myKeysDown();
Your code hook:
#include "SM64DS.h"

bool doNothing = false;

void hook_020e50ac()
{
if (CHARACTER == CHAR_Mario)
{
myScanKeys();
if (myKeysDown() & KEY_SELECT);
{
if (isOnGround)
{doNothing = true;
doNothing = false};
else
{Player_PerformAction (MarioActor *, char 0x9A, unsigned int loop_related, unsigned short playspeed_20_12);)}
}
}
}

The possible values are as follows:
KEY_A = BIT(0), //!< Keypad A button.
KEY_B = BIT(1), //!< Keypad B button.
KEY_SELECT = BIT(2), //!< Keypad SELECT button.
KEY_START = BIT(3), //!< Keypad START button.
KEY_RIGHT = BIT(4), //!< Keypad RIGHT button.
KEY_LEFT = BIT(5), //!< Keypad LEFT button.
KEY_UP = BIT(6), //!< Keypad UP button.
KEY_DOWN = BIT(7), //!< Keypad DOWN button.
KEY_R = BIT(8), //!< Right shoulder button.
KEY_L = BIT(9), //!< Left shoulder button.
KEY_X = BIT(10), //!< Keypad X button.
KEY_Y = BIT(11), //!< Keypad Y button.
KEY_TOUCH = BIT(12), //!< Touchscreen pendown.
KEY_LID = BIT(13) //!< Lid state.
