Fine Firebar Speed Control
repl_0213ED20_ov_18:
        CMP     R0, #0
        MOVEQ   R2, #0xC0
        MOVNE   R2, #0x100
        LDR     R0, [R4, #8]
        LSR     R0, R0, #20
        CMP     R0, #0
        MOVNE   R2, R0
        ADD     R0, R4, #0x1C00
        LDRH    R1, [R0,#0xC0]
        B       0x213ED34


If Nybbles 5-7 are free, firebars behave like original game. Otherwise, the firebar uses speed defined in those nybbles. Original game uses "0x100" for fast and "0xC0" for slow. You can, with this, use 0x1 (practically stationary) - 0xFFF (hell on land)

Mess with animations hardcoded to tileset ID
repl_020BCE4C_ov_00:                    @ R1 = Tileset ID
        LDR     R2, =0x208B168          @ Pointer to block 1

        CMP     R0, #7                         
        BNE     .TryForSlot31
        CMP     R2, #7
        BNE     .TryForSlot31
        MOV     R2, #1
        BEQ     .TurnOn                 @ If both BG IDs = 7, turn on lava waterfall animations.
       
.TryForSlot31:
        CMP     R0, #31        
        BNE     .NotLava
        CMP     R2, #31        
        BNE     .NotLava
        MOV     R2, #1
        BEQ     .TurnOn                 @ If both BG IDs = 31, turn on lava waterfall animations.
       
.NotLava:                               @ Well, the BG IDs don't match, but let's check if we can enable snow animations.
        CMP     R1, #3                  @ For tileset ID 3...
        MOVEQ   R2, #2
        BEQ     .TurnOn
        BNE     .Exit

        CMP     R1, #17                 @ And for tileset ID 17.
        MOVEQ   R2, #2
        BEQ     .TurnOn
        B       .Exit
       
.TurnOn:
        LDR     R0, =0x20CAC7C         
        STRB    R2, [R0]

.Exit:
        B       0x20BCE84               @ Exit.


Sometimes I wish Nintendo fucking dead.

The above code restores the functionality of the original game, except that it turns on the lava waterfall animations based on the BG slot ID, and not the tileset ID.

Adjust/remove code to suit your animation needs.

Infinite Lives

#include "nsmb.h"

void hook_020CF108_ov_08()
{
        u32 *lives = (u32*) (0x0208B364); //Pointer to lives
        *lives = 99; //Variable 'lives' is always set to 99
}


This hack sets the life counter to 99 all the time, making 1-UPs pointless. (Something that's in Odyssey)

The necessary files for this are in Overlay 1.
NCG is at 0xE64, 0x5EF long,
NCL is at 0x1454, 0x200 long, uncompressed,
NSC is at 0x1654, 0x1F0 long.

Decompress the NCG and NCL once you import them into the filesystem. The file path cannot contain spaces.

Use the (unoficial) b380 version instead. It's by far the best version of the editor yet and can decompress overlays. Link: http://nsmbhd.net/file/d86fa4d5bfb663c65bde/nsmb-editor-380b.zip

Auto-Run

Use this nsmb.h: https://nsmbhd.net/get.php?id=udc73BCXlMYd9CJg

Code:

#include "nsmb.h"

void hook_0211F840()
{
        MarioActor* mario = (MarioActor*)getPtrToPlayerActor();
        mario->xVelocity = 0x2000; //Change this value to change how fast Mario/Luigi run.
}


Video:



Makes Mario/Luigi continuously keep walking through-out the entire level, like in Super Mario Run.

Blocking Left/Right DPad inputs might be a good idea tho.

You can also make this a hack a little more optimized by making MarioActor parameter 1 of the hook as MarioActor::Move is a member of MarioActor.

#include "nsmb.h"

// void MarioActor::Move(void) Hook
void hook_0211F83C(MarioActor* player)
{
        player->xVelocity = 0xBAD1DEA;
}

Disables the timer from decreasing, allowing for infinite time.

IIRC you can have infinite time if you set the timer to 0. Or maybe I’m thinking of something else

LDR     R2, =#0x424
STRH    R0, [R4, R2]

repl_0215663C_ov_36:

BX      LR


Replaces the glitchy "Disable Sound" nybble as multiplier. Basically, entrance = (Disable Sound Nybble) * 16 * (Warp Area Nybble)

Small request here.

I'm looking to force the game to always load one entrance type (the default entrance). It would be handy to use for some hacks but mainly MvsL hacks, as it is hardcoded to always use the pipe entrance.
