Well, it wouldn't make sense to post a separate thread for each and every patch, so instead I'll collect them here.

These patches should apply to both EUR and US versions, unless stated otherwise.

I. Direct ROM patches

How to apply

Using an older (r356 seems to work) revision of NSMBe, decompress the overlay specified in the last column of the table. Extract it out of the ROM. Then, using a hex editor, search for the values in the "Search in ROM" column one line at a time. Replace them with values in the "Replace with" column. Once done, save, and import back into the ROM using NSMBe.

If an overlay isn't listed, you have to decompress all overlays and search the entire ROM.

II. ASM Template Patches


How to apply:
1. Set up the ASM Hacks template using DevkitPRO.
2. Open up "Makefile" in a text editor and change this line:


Replace the "X.X.X" with whatever version your installed devkit has. Find this out by going to C:\devkitPro\devkitARM\lib\gcc\arm-none-eabi\
or whatever location you installed devkit to.


3. Make a file with extension .s in the "source" folder. Paste the code copied from this topic there.
4. Put a ROM in the template folder and open it in NSMBe.
5. Insert the code into the ROM by pressing "Run make and insert" on the "Tools/Options" tab in NSMBe.

Other useless notes:

Can you load unused levels with this? Like 6-Cannon?

Yeah.

How do you change these, with desmume's memory viewer?

Paste the address into the box, press GO, then change the value. The last number of the address indicates which one it is in the row.

I used the U rom. Here are some 'results':


World 1-Pipe (not really)


World-6 Cannon (yes really)

Do you know how to stop the timer just in one specific level?

sry guys...

That's not hard: Just read some Level Variables and the timer will be stoped by a small if-operation.

You'd need to give me a patch to make the ROM into the one you've edited first to do that.

Or, if you want to patch a new rom, I'd need to know which one it is.

Well, added a patch to make it so the screen doesn't switch when you check the "display on bottom" option, so you can use it as inventory prevention.

But, not sure how to make the item also be greyed out. You can't get it, but it still appears colorful. I found when the check for this is done, just not sure how to rewire it into activating anyway.

nmp will not carry over all the files, so I'd recommend an xdelta.

Sorry skawo, I'm stealing your thunder here.

World progression follows sequential logic


Decompress overlay 8 and edit those bytes:


For US rom only.

Can u please write the exact adress? I cannot find it
But you meant overlay9_8 with "overlay 8", right?

Hey, that's cool. Hopefully the world progression tilemap's easily editable, too.

Yes I meant overlay9_8, but you have to use older revisions of NSMBe to decompress the overlay because the button is broken on later versions (use r356, this is what I use).
Overlay 8 is 139,360 bytes once decompressed.
The addresses are indeed the correct ones, but this is true only when the overlay is decompressed



That make me think of something ! I wonder if Mario's movements on the map are changeable too, especially to fix that glaring movement mistake on World 4 map when Mario take the route between W4-1 and the secret green Toad House, if you see what I mean.

Hahah, I never noticed that. It probably CAN be fixed, if you knew where the path data settings were.

Added two patches: one raises the amount of fireballs you have to shoot Bowser Jr. with for him to die to 18 (just like in NSMBW). The other makes groundpounds do the same amount of damage as normal jumps; not complete, as he still dies if you first do a jump and then groundpound.

May do the first patch for all the bosses if I decide it'd be a good idea to use in Newer DS or if someone would want those patches.

Er... How do you set those codes in NSMB?
