Hello everyone,

The hack I am currently working on will most likely be a one or two world hack.
Now I thought about the possibilities I have to end my first/second world.
What I mean is this: If you finish my levels, the credits should start playing and you won't be able to access the other worlds, only the edited ones.

So I tried around with the castle boss of the first world:
I replaced the W1-Boss Room with the W8-Final Boss Room. I thought that this would solve my problem.

But beside some strange particles that were wrong or not there in the first place, the game crashed every time (and in some cases were I just rebuilt the FInalBoss Room, BowserJR. started teleporting at the beginning of the fight) MelonDS and DeSmuMe both were not able to let me beat the boss.

So I though "The final boss is too hard for the emulator" but when going to W8, the Final Boss worked perfectly and the partficles and everything was back to normal.

Would be happy if someone can help me with this

The worldmap engine can set a flag that tells the game that it should go to the next world if a level is beat.

If you are in world 8 this flag causes the credits to roll.

Also the boss crashes because the particles are incorrectöy loaded as these are hardcoded.  skawo made an asm hack for that. But if you would be able to kill the boss it would end the level like it did before.

A potential solution would be just disabling the "go to next world flag" in world 2 causing all later worlds to be unlockable.
Another way would be hacking the world id when beating world 2-C to 8. But that might glitch the save file and would require further hacks. The cleanest solution would be modifying the code that checks if the flag is set and if you are in world 8 to world 2. But I do not have an idea where that is done.

Ok, thanks to  skawo's ASM hack the boss does not crash anymore. That's at least something




By that, do you mean you don't know how to hack the world ID, or do you mean both possible solutions you suggested?

I know how to modify the flag. The world id can be found with a quick ram search in desmume (the one that ports you to the world when changed in ram).

Just to clarify: You are talking about the Cannon Level from World 2 ("...hacking the world id when beating world 2-c..."). And by hacking it you mean change it's destination to World 8? (because that can be done without RAM Search and with NSMBe)

And that's not the same as modifying the world flag, right?

you can also make 1-1 a cannon that goes to world 8 and edit that instead

or maybe put the cannon at the end of world 1-castle, like in the Wii U or something

No problem BooChewbaca! Of course, if you had the cannon at the end of the castle, it'll just take you to world 8, and not the boss. Maybe you can use a Pipe Cannon or something

what do pipe cannons have to do with anything. I think there's a way to have the cannon only available after the boss without keys. put the key location sprite outside the view and use a zone to detect when the boss dies and unlock a room with the cannon. it's untested and might not work but it's worth trying.

It's just an idea I mean after you go through the door, you have a cannon that blasts you to the airship. AKA, the boss. Like in NSMBU
