I understand that Toad's Tool currently does not edit the sky's actual textures in the texture editor. But can a stage's sky texture be changed to another stage's sky texture?

For example, I want the slide areas of Tall, Tall, Mountain to have the same blue sky texture as Bob-omb Battlefield instead of pitch black.

I can't find a relevant topic this should belong in, so it's okay. Although if someone knows of a larger topic it could be put in that is relevant, feel free to note it.

(It has been a while since anyone has asked a relatively 'unique' question, heh)

Theres an older topic called background swapping. That may be a suitable place.

Not possible at the moment. However you can use this tool:

http://www.mediafire.com/?jdtdlmmjwoz

It changes all backgrounds into the boo's haunt one. You can somehow change that option though.
And one more thing: It doesn't change the slide backgrounds because the slides
doesn't have a background. I am unable to answer if this could be changed however.

Okay, looking through that old thread I found this.

The list might be useful to those wanting to change backgrounds before TT64 v6.0 is released someday.

One thing that messiaen left out in his original list is the fact that sub areas can have different background settings. Most of the time though, the sub-areas have no background (The exception is Tiny Huge Island, where area 2 has the same bg as area 1).

Areas that have no background still have a 0x19 command in the level geo layout script, but the last four bytes are set to "00000000" instead of "802763D4", and the one byte parameter before that is set to "01", except in the case of Tick Tock Clock, that has "FF" as a parameter for some reason. My list also include the ROM address of the related 0x19 command for each area, so you can find it easily if you want to change it.

Edit: fixed the 0x0A banks addresses.

Now, if I understand correctly, if I change this.

31 | Tall Tall Mountain | 01 | 00B35715-00B55855 | 004EBC80 : 190000 00 802763D4
31 | Tall Tall Mountain | 02 | 00B35715-00B55855 | 004EBD6C : 190000 01 00000000
31 | Tall Tall Mountain | 03 | 00B35715-00B55855 | 004EBDFC : 190000 01 00000000
31 | Tall Tall Mountain | 04 | 00B35715-00B55855 | 004EBE94 : 190000 01 00000000

to this

31 | Tall Tall Mountain | 01 | 00B35715-00B55855 | 004EBC80 : 190000 00 802763D4
31 | Tall Tall Mountain | 02 | 00B35715-00B55855 | 004EBD6C : 190000 00 802763D4
31 | Tall Tall Mountain | 03 | 00B35715-00B55855 | 004EBDFC : 190000 00 802763D4
31 | Tall Tall Mountain | 04 | 00B35715-00B55855 | 004EBE94 : 190000 00 802763D4

Then the game should load the blue sky instead?

If thats right, how would I go about changing those values? Would I use a hex editor or is it more complicated than that?

*Alot of code and tecnical stuff*

Now, if I understand correctly, if I change this.

*More code*

*Still more code*

I'm no pro, but that looks like hex to me, but to be safe, make a copy of your rom before modifying it in hex.

Guess this thread will supersede that old one then. I'll edit the title so people know to look in here.

Also for anyone who is wondering, to change a main levels sky texture you will have to edit the commands in the 0x0A Bank not just this byte 190000 [06] 802763D4 because if you just change the byte the textures are still pointing to the same background so it will stay the same
