Bet your school choir can't do something like this.

Let it be known that the first thing that jumped to mind when I heard that was this

[Sammy_P]

BUMP.

I wish i had that game, Qloof.

[Sammy_P]

D-P.
It won't work!

[billy bob]

D-P.
It won't work!

What won't work?

(P.S. I have that game( I got every single star coin and shortcut possible(. Which means I have completed the game(. I still play it on Wednesdays))).)

[Sammy_P]

It wont let me do 1 Player or 2 Player Mode!

Darn it, I got the crappy DS version instead of the Wii version. I want that game so bad, but I don't have a Wii and my mom won't let me get one, so meh.

You're probably not pressing the right buttons. Please check the controls on the first page.

[Sammy_P]

I got it working.

Off to level 1-B!

[MyNameIsKooky]

Cool!

I've been trying to organize the extra areas into a hack, but the game RAM keeps glitching up when I try to edit out any things that crash the game.

[Sammy_P]

Hmph. OK.

I'm at the library, and I need to do about 4-6 math lessons.

[MyNameIsKooky]

BUMP.

I'm much more experienced at Super Mario Brothers hacking now. I've recognized the majority of the ROM.

I can now modify enemy behaviours, object behaviours, palletes, world tuning, and lots of other SMB stuff through Hex-Editing.

If anyone has any requests, just ask me and I'll see if I can try to post a hack of your request. Or just pictures if that's illegal or something.

[Nobody]

YOU WOULD POST PICTURES IF THEY WERE ILLEGAL?

Since you don't seem to bother with legal matters, is the download itself legal?

[MyNameIsKooky]

I've heard. I can post pictures, though.

[Sammy_Bro]

BANG BUMP BONK.

I really wanna see the castle levels!

[MyNameIsKooky]

Every area both real and extraneous can be found at http://1st.geocities.jp/bysonshome/smb1 ... 56a_2.html

EDIT: The download for the ROM has been deleted. Google "super mary [p1][!].nes rom" (without the "s) and click on the 3rdish result. The ROM is called super mary [p1][!]. It's found by the bottom of the list. Download that.

It's not there.

[Qloof234]

EPICBUMP

@LittleZBot; Try googling for "Super Mario Bros. NES ROM" instead. It might work.

Anyways, I have created a theory as to why the infamous Minus World glitch happens (not the clipping through wall part - that's a collision error).

So. This is based off of two assumptions:

1) There's a list of values that any warp pipe (including ones that aren't warp zones) can use. These values are levels to warp to.

2) Once the "WELCOME TO WARP ZONE" text is loaded, it activates the warp pipe's proper values.


Alright, so. How it works:

The default value for a warp pipe is null, ergo it references another data set entirely. Every pipe has a value that tells the game if Mario can use it to warp. By default, it's off, except in the warp zone, where it starts on.

Any pipes in the Warp Zone only "activate" - as in use their proper level value - once the text shows up. Assuming this is correct, these two assumptions cause a huge mistake.

If Mario enters the pipe before the text is loaded, it still references a value that has nothing to do with warp pipes - ergo, it loads the Minus World instead. Likewise, the second pipe (if you move towards it) also loads another world entirely, only it's an actual world.


I don't know if this is accurate - it's just my assumption based off of how I think SMB handles warp pipes.

I've seen an actual technical explanation some time ago. I forgot most of it but basically the game relies on the pipe's on-screen position somehow. There are a few other pipes that are possible to fake out under TAS conditions. One such trick is pulled off in the TAS to get through world 8 faster, IIRC.

EDIT: Sorry, I messed up. Those two glitches are apparently unrelated:

it's just an oversight of the programmers that you can get into the pipe before the correct warp labels are assigned.

And here's the alternate pipe glitch:

Theory: The game can have only one "entry point" (a pipe or vine) per screen. The reason lies in how the game is designed: There is just one global variable in the game RAM that determines where pipes or vines in the current screen lead. Once the screen scrolls far enough for the next target label to be loaded from the level data, all entry points in the current screen will lead to that place.

Copied from TASVideos.

[MyNameIsKooky]

If the text isn't loaded in the World 1-2 Warp Pipes then you'll get the World 4-2 Warp Pipe sequence, which is why the second pipe leads to World 5. Since World 4-2 only has one warp pipe, it has to make the other numbers for the other two nonexistant warp pipes an invisible character, in this case character #36. If you would place two more pipes and enter either the lefthand one or the righthand, you would end up in World #36, which happens to be the Minus World.

I know tons about the Super Mario Bros. ROM and how it works, but I don't know why it loads the 4-2 Warp Zone in World 1-2 before it finishes scrolling.

Oh, okay. My guess then is like with some other games, World 4-2's warp zone is what's loaded by default until the sequence calling the right warps is loaded.

Why don't you like the DS version?
I have both, and I think the Wii version is better, but the DS one is still fun.

[MyNameIsKooky]

There's like Yoshi and stuff and the DS version is too easy.

[Qloof234]

Just that Nintendo made Yoshi essentially useless because you can only have him in the level you find him in.

[MyNameIsKooky]

Oh. Figures.

Anyways, for those of you who like severe level scrambling and tile glitches:

1. Open ROM
2. Go to address $1C19
3. Change the number at address $1C19
4. Play Super Mario Brothers
5. ?????
6. PROFIT

[DEEMAN223344]

7. Jail for reselling a ROM.

[MyNameIsKooky]

You ruined the meme.

[Nobody]

8. Meme ruined
9. Angry MyNameIsKooky
10. DOOM

[DEEMAN223344]

9. ROAR YAY, NOW TO REPLACE MEME.
10. PROFIT.
11. D'oh.

[Nobody]

12. You were too busy to notice that 10 came before 9.
13. You were too busy to notice that until now this wasn't a You Know You're Living in 200_ If..._
