SMB2J Hex offset list

SMB2J Hex offset list
By Insectduel

This is the place where you find the hex offsets in Super Mario Bros. 2J for the FDS. Because I knew almost all the data in that game, I decided to share some of the data I’ve collected.

Some offsets may be the same as SMB1 but some of them may be altered in a different way.

These offsets will help me create a new level editor that supports FDS version so I will be able to do it instead of Hex Editing.

Altered Data

A standard data that is Hex is mostly changed with different offset numbers.

Basic Data

Data with the same Hex offsets.

Here’s some of the data that I’ve collected.

Object list numbers

An altered offset data with objects that were used in the game. Some objects will only be used with World 5 and above.

Each room has it’s own grid on a page. Some objects will be placed differently on a single page. However if object of the page is flagged, the hex changes differently or perhaps is moving to the next page.

00-7f Base object

80-ff Flagged object

There are many different types of objects on a single page. Because the each object has the hex code to place the object in where it should be.

Here is the grid on the next page.

Grid with objects placed

This is an example of an object placed in World 1-1 in Room 1. The following items were placed as stated.

(X,Y ##)

X= X- position Y= Y - position ## Object number

These are the descriptions

1e E4 Length 5 Vertical Block

23 24 Length 5 Horizontal Brick (Seaplant)

27 23 Length 4 Horizontal Brick (Seaplant)

37 07 Brick with Mushroom

66 61 Length 2 Vertical Block

AC 74 Length 5 Horizontal ? block (Coin vertical 7)

C7 01 Poison ? Mushroom

If you already know this, congratulations, That means you know the basic part of the objects in the Editor.

I have listed objects that were used in SMB2J. However in this case you will also need to know where the objects placed in X or Y position.

I name the objects that were classified in the Y part of the position.

Objects 0-B Standard Objects

Object C Ground Based Objects

Object D Generated Objects

Object E Brick scenery and Season change Objects

Object F Vertical based Objects

In Super Mario all-stars, the Vertical based Objects were considered as 3 bytes instead of two. Which makes it harder to edit levels or to understand with. I don’t know much about Mario all-stars except for SMB3, which is the only one I knew.

Here is a list of objects that were standard

Note: Objects 60-7f will only work if you are in World 5 and above.

Sprite list numbers

The offset you see Sprites set up in different positions. The hex data is almost the same as the original version but some new ones existed. This hex string is basic.

The sprites and the areas are separate so put them wisely. I advise you not to insert the 3-byte sprites because the sprites will be corrupted all over the area. I will explain about sending and adding objects a little later.

Grid with sprites placed

As you see the sprites highlighted in blue represent the sprites place in World 4-2.

What about the E.

This spot is where you set the areas. The byte represent

XE RR VV

X represents the horizontal area you currently placed while the E is the current spot. R represents the room change where you set from 00-7F. And V represent the page number of the current area setting in the rooms above. For every F after the odd number from the left, it changes the world of an area.

Examples

CE 42 42

Position C, Room 42, World 3 page 2

DE AD 00

Position D, Room 2D, World 1 page 0 (Flagged Room)

EE 42 25

Position E, Room 42, World 2 page 5

Very important: Don’t do this if you can’t exchange the areas from one room onto another. It would be wise if a professional hacker could do this part.

Sprite F

Page skip header data. Lasts up to 255 pages.

Room header data

The hex codes will allow to change the room header in SMB2J. Some levels require World 5 or World 9 to enter.

About Adding and Sending Objects

This is the stuff you need to know when you edit levels.

Adding Objects

When you add objects, it ripped off objects from another room. Adding too many objects will make the game corrupt and it is nearly impossible to fix this problem.

Sending Objects

When you send an object it inserts the Hex data onto a level offset and other one decreases the number of that number. I’m not sure about Hex stuff when sending an object but it would be easier to compromise what level you made.

Sending Enemies

Sending enemies may decrease the Hex number and sorts them onto another position. Again, I don’t know much either.

Inserting Areas

Inserting an area without sending off will cause the enemies to corrupt themselves all over that one room.

Other Hex Data

Data is nothing to do with the game. Just some fun stuff

Music Data

Song played in water (02= water music)

Song played in Ground (01= Overworld music)

Song played in Underground (04= Underworld music)

Note: That data did not come from me. Sorry, just don’t credit me for that.

Level Header

For every level, the very first two bytes are the level attributes.

Graphics - Level Attributes - BASIC BLOCKS

TTSSsBBB ccDDbbbb

TT = time = 0,400,300,200

SS = Start = fall,stand,slowf,walk

s = part of the above I think

BBB = Background = day,sea,wall,river,night,snow,nightsnow,castle

cc = pipe color = green,red,grey,cloud

also style = trees,mushrooms,bullet bill,cloud

DD = foreground = nothing,cloud,mountain,fence

Level Header
----------------------------
The first two bytes of a level are it's level header. The level
header is broken up like this:
( byte 1 ) ( byte 2 )
t t a p p b b b - c c s s g g g g
=================================|===================|
|_| | |_| |_|_| |_| |_| |_|_|_|| ground/block |

=====================================================|

ground/block type: defines the type of ground structure for a level, this can
be how high the ground is and how low the ceiling goes (if there is a ceiling).

scenery type: determines what will be put in the background
clouds

00 = none
01 = clouds
10 = mountains/hills
11 = fence/trees

compliment: affects the palette somewhat, but mainly determines what the "trees" look/act like
00 = trees
01 = mushrooms
10 = bullet bill turrets (they work too)
11 = the cloud world (the ground is a cloud)

background/season type: this is mainly a palette attribute, but does serve another purpose.
When this attribute is less than 100 (0x04), the background is effected, anything higher
and the palette is affected.

000 = day time (normal palette)
001 = underwater background
010 = caste wall background
011 = over water background
100 = night time
101 = day time/snow
110 = night time/ snow
111 = black and white (castle)

This may apply to the other data

Level Header Hex numbers

Byte 1

Halfway page: See Crazy Hex Strings

Crazy Hex Strings

This is where the hosted data came from in SMB2J. I advise you to use an emulator like FCE Ultra or RockNES Version 1.700 because these are the emulators that actually work on FDS hacking games. NESten, Nester, Fwnes or Famtasia will not work.

The Hex Editor like Transhexlation is required to do this. DO NOT FORGET the Disksys.rom in the same folder as the emulator is because this is how to play FDS games.

Harder Mode

12379=0x305B

Original Offset A9 01 8D 74 07 20

Changed Offset A9 01 8D 6A 07 EA

It allows to transform Goombas into Buzzy Beetles like on SMB1 after beating the game. Don’t give me credit.

Warp Zone

10426=0x28BA

Original Offset 02 03 04 01 06 07 08 05 0B 0C 0D

Changing the values you see here will change the Warp Zone you want to go. You cannot go to World 9 in this way. However going to World A or above may crash the game.

Room Change

Original Offsets

34062=0x850E

World 1 20 29 40 21 60 and so on

34080=0x8520

World B 22 2C 00 23 61

World C 24 25 26 62

World D 27 28 29 63

Changing the values will change the rooms you want to go. This is my favorite. Even you can play beta levels with the unknown values. Some rooms can only be activated in certain worlds.

True character of Bowser

25892=0x6524

Original Offset 06 00 02 12 11 07 05 2D 2D

Changing these values will allow to change the sprites when Mario defeats Bowser with fireballs. Using sprite 04 is NOT Recommended in Worlds 4 and below.

Running Hammer Brothers

20671=0x50BF

Original Offset 95 58 AD 5F 07 C9 06 B0 09 AC CC

Changed Offset 1 9D A2 03 95 58 AC CC 06 B9 26 C3 9D

Changed Offset 2 95 58 AD 5F 07 C9 XX B0 09 AC CC

These offsets will allow how long the Hammer Brother will wait. The X represent in changed offset 2 to select the World will the Hammer Brother will run without wait.

Don’t give me credit for this.

Shooting ASM

17218=0x4342

Original Offset 02

Original Offset 02

Changes the number of life counters when you start the game. The life counter’s Max limit is 7F or 128 lives.

Castle GFX in Sea attributes

13365=0x3435

Original Offset 07

Changes the GFX tiles when you are underwater depending what world you are in.

Bowser’s Hammer Routine

Allows Bowser to Stop Breathing Fire depends what world you are in. Don’t give me credit.

Bowser that breathes fire

24368=0x5F30

Original Offset 07

Allows Bowser to Start Breathing Fire depends what world you are in. This only effects the current world you are in. However in this case World 9 Bowser didn’t breathe fire in SMB2J.

Speed Text

45057=0xB001

Original Offset 07

Extends the speed of a message after beating Bowser

General Setting 1

9326=0x246E

Loop ASM Data. Changes the loop command in 20117=0x4E95 - DA

Loop ASM Data

20119=0x4E97 to 20148=0x4EB4

Loop ASM Data. Changes the loop command in 20146=0x4EB2 - 8D

I may have tried the loops in SMB1 but it looks a bit glitchy with World 3.

Star count

52284=0xCC3C

Original Offset XX (May count if you beat World 8)

Allows you to count the number of stars in the Title Screen. If you have more than 8 stars Hold the A Button and Press Start. You will be going to Worlds A-D. I didn’t get credit for this. The Mushroom Kingdom website show me that cheat that I didn’t know. Thank SSM for showing me this offset.

Tile for Stars in Title Screen

34650=0x875A

Original Offset 26

This may change any tiles replacing Tile 26 in the Objects column in the Title Screen.

Timer Change (Not the level’s header)

Original Offsets 04 03 02

Changes the timer of a level with timers 400, 300 and 200.

GFX for Vertical Balls

11495=0x2CE7

Original Offsets 24 2F 24 3D

These vertical balls GFX change the following

Rope: A2 A2 A3 A3

00 Small

01 Super

02 Fire

World Pointers

34053=0x8505

Original Offset 00 05 09 0E 12 17 1C

This is kinda fun but it allows the number of levels to load for each world. Works for Warpzones as well.

Sprite change

20370=0x4F92

It allows which enemy single Goombas turn into on second quest. I recommend 05 for a challenge... Requires Hard Mode offset to do this. Don’t give me credit.

Goomba Trio Sprite change

21741=0x54ED

Original Offset 02

It allows which enemy pairs and trios of Goombas turn into on second quest. Using 05 here creates a REAL challenge... Requires Hard Mode offset to do this. Don’t give me credit. This will be pained if you insert the Running Hammer Brothers in World 1 or World A.

Fire Mario Palette Brightness
