Move Petey Piranha and Mummypokey bosses to different worlds

There's some absolutely retarded code that deletes Peach if Worlds 2 and 5 are cleared when you enter the boss battles with Mummypokey and Petey Piranha. If this code isn't adjusted and you move the bosses to a different world, this happens if you try battling them again:

Hooray. Here's the fix;

-------
010050E30C00001A7C009FE5 -> 0X0050E30C00001A7C009FE5
040050E30B00001A48009FE5 -> 0X0050E30B00001A48009FE5
-------
010050E30300001A34009FE50010A0E3 -> 0X0050E30300001A34009FE50010A0E3
040050E30200001A20009FE50010A0E3 -> 0X0050E30200001A20009FE50010A0E3
-------
94009FE5200090E5010050E30100000A040050E3 -> 94009FE5200090E50X0050E30100000A0X0050E3

200090E5010050E30100000A040050E31B00001A9F3AFBEB -> 200090E50X0050E30100000A0X0050E31B00001A9F3AFBEB

200090E5010050E30100000A040050E31C00001A0000A0E34571FBEB -> 200090E50X0050E30100000A0X0050E31C00001A0000A0E34571FBEB

200090E5010050E30100000A040050E31C00001A0000A0E3BB6EFBEB -> 200090E50X0050E30100000A0X0050E31C00001A0000A0E3BB6EFBEB

Replace the Xes with the world numbers your relocated bosses appear in. The first two patches go together, so put the Mummypokey boss in the first one and then the Petey boss in the second one.


Out of curiosity, could this work in MvL?

Not content with my latest code, I decided to upgrade the mod so that you no longer have to use Sprite 231 (Water):


Wavy backgrounds:
repl_020B181C_ov_00: MOV R10, #0 @Assigns a value of 0 to R10 BX LR @Returns repl_0215E9E8_ov_36: STMFD SP!,{R1-R3,R12,LR} @Pushs R1, R2, R3, R12 and R14 in the stack STR R0, [R4] @Stores the Level Actor BL 0x20B163C @Calls the function that allows the backgrounds to move in a wavy fashion LDMFD SP!,{R1-R3,R12,PC} @Pops R1, R2, R3, R12 and R15 from the stack


For those who are not familiar with the ASM-Template:
_In Notepad++, create a new file
_Copy/paste the code above
_Save the file with an extension .s (for example wavebg.s)
_The file must be located in the Source folder of the ASM-template
_In NSMBe, click 'Run make and insert'

You can also read this thread that explain what is the ASM-template and how to use it:
http://nsmbhd.net/thread/1281-how-asm-hacks-are-setup-tutorial/


If someone wants the code without having to use the ASM-Template, I can post it too.

Copy/paste in an empty file in Notepad++ and save as ****.s (for example blueshell.s).

Basically if you run at max speed, you have to press (and maintain) D-Pad_Down to get Mario rolling in his shell, otherwise he runs as he would without a shell.
Also Blue Shell's speed is increased under the effects of a Starman.

Actually, you can also just use Windows Notepad :')

EDIT:



This is how it'll look in-game.

On the topic of codes, however, they do also stop functioning - well, some of them -- after my ASM is applied. So there's that. Applying the template moves something.

Actually the answer is quite simple:

At offset 0×2065F10, you get the arena starting offset, which is normally 0×21901F8.
At offset 0×203A784 (which is the one I use for consistency), you get the first arena item offset, which is normally 0×2190200.
Custom ASM Hacks from the ASM-Template begin at offset 0×21901E0, thus shifting the arena offset further.
The more ASM hacks you put in, the more that address will be put higher and higher.

In other words, if one of your mods needs to fetch something at an offset above 0×21901E0, chances are you will need more LDR Rx, [Rx] than expected.

The latest Blue Shell code I did take into account that particularity.
You shouldn't have any problem now porting this into Newer Super Mario Bros,  skawo.

Thanks for these, MeroMero. In particular, the second will be very useful.

Here are the files *.s, you can use these instead of creating one .
wavebg.s
blueshell.s

I don't think those download URLs were really needed. I mean, if you don't know how to make a text doc and change the extention, you shouldn't even try inserting an ASM Hack in NSMBe, using the Template.

Well, the files *.s were not only for those who did not know how to create one.
They served, too, for someone who did not want to create your own ...

Very, very nice.
Could you do the mini mushroom gravity thing like this too?

For some reason I thought I had posted it already but no, so here it is:

Light gravity fix for ASM-Template:

Awesome!

I'm also porting the pipe fix, that's what I have so far:
nsub_021175B0_ov_0A: MOV R12, LR MOV R2, R12 CMP R3, R12 BLT 0x21175C0 B 0x21175E4 nsub_0211761C_ov_0A: LDRH R2, [R0, #0x64] CMP R2, #0xB000 @Check if Mario stands atop a World-Cannon LDRGTH R3, [R0, #0x66] ADDGT R3, R3, #1 STRGTH R3, [R0, #0x66] MOVLT R3, #0x2000 STRLTH R3, [R0, #0x64] LDR R3, [R0, #0x930] B 0x2117620


The second one is still WIP but you can use the first one already.
What the first patch does is that it calibrates Mario's position upon entering a vertical pipe to be exactly at the center, every time without fail. Mostly useful to hide the Blue Shell.

Ah, OK. Noted.
