Title: Super Mario Land 2 lost bytes
Post by: Raccoon Sam on April 13, 2008, 07:54:15 AM

The graphics of the upper left corner of a Mushroom house can be found in the ROM.
There probably was a mushroom house in one point, but got removed at the last moment or something. There's still a Mushroom House in the World Map.

Interesting. How do you hack graphics out of an NES game?

Maybe they just changed the design.

My bad.

But still, how do you rip out graphics out of a Game Boy game?

Shameless 120 day bump, but hey; a contribution!
There's an unused cloud sprite in the overworld. Normally you wouldn't see anything above the Pumpkin Zone, but if you go to 0x3CC04 and change FF to 09, you will have a fully functional cloud above the area. The sprite works like any cloud would, but for some reason its sprite number had been set to FF (nothing) by Nintendo.

Mr. Cloud looks so lonely.

I'll make a rom patch.

edit: The cloud is not present in the 1.0 version of the rom. I'll try 1.1

There is no cloud still and I know how to use a hex editor.

I used 1.0 US version, and I'm fairly sure I gave the right offset...
Let me re-check.
EDIT: Yes, it is 0x3CC04. Are you sure your ROMs are clean dumps? Here' the string you should look for (with the FF to be changed bolded):
FA CD C8 4F C9 00 4C 4F 01 10 78 36 FF 10 A8 F0 09 01 C0 28

I wasn't using a clean dump until after I downloaded (1.0) "(!)". The bad dump had a completely different set of bytes than the one you posted even at the same offset. This works with all versions of the game.

Here's the .IPS file. I used 1.0.
