Does anybody know the location of the files for the falling snow effect for the World 5 Map? Also, in the world 5 map, there are some patches of snow on the ground that only become noticeable when the texture for the ground is changed, and I would also like to know where the file for those are.

The falling snow effect is the 40th particle in root/particle/spl_coursesel.spa. Spa files can't be edited by any editor that I know of but can be viewed in MKDSCM. If all you want is to get rid of the particle, you'll have to find it in a hex editor (no need to lz decompress the file beforehand) and replace it with 0s.
As for the second question, well, I don't know.

Ok, thanks.

EDIT: Would you happen to know the offset at which the effect is located?

Not exactly. It seems to be somewhere at the end of the file. I have succesfully removed the particle but it seems I have accidentally affected other particles while doing so. You'll have to go with trial and error.

Ok, then. Thanks for the help.

You don't need to change the palette, just replace the image with 00 bytes.

Thanks! I finally removed the effect!

Hello, I'm a non-native english speaker who has recently started hack NSMB, frustrated by the lack of slopes from Super Mario Maker (before the announcement of SMM2 x) ).

Thanks to the many tutorials that I translated for days, I know how to hack the game on the main lines (create a tileset, change backgrounds, camera...). My problems seem derisory in comparison, sorry if the answer is obvious.

• How to remove aquatic properties from an aquatic area? (like Level 1-A Area 2) And the opposite, transform an area to an aquatic area?
• Is it possible to prevent a background from being animated? (Like torches in Castle)

Thank you in advance!

to prevent background animations, find the animations file (https://nsmbhd.net/thread/3276-tilesets-and-backgrounds-name-table-guide/) and delete the graphics. to remove aquatic properties from water levels, remove the water sprite.

I don't see water sprite in full-aquatic area, even with "search" function (if it's about sprite 231).

You're right. I didn't even know that was a thing. In that case, export another level as nml an import it over the aquatic level you're trying to edit.

Oh, I didn't think about it. Indeed, it is the best solution. Thank you!

Is there a discord server for this website?

No, and don't go setting one up.

We do have an IRC channel, otherwise everything is on this website.

How do I change the track that plays on the title screen? I'm not looking to edit the music entirely, just to change what plays on the title screen.

you have to replace the files for the title screen music in the sdat with the files for the music you want to play.

If you just want to change the music ID you can do this

1 Decompress overlay9_9.bin using NSMBe b356

2 Click on Hex Edit

3 Type 74A4 in the offset box and click Go

4 Replace the selected 1B with the ID of the music you want

5 Now go to offset 74B0 and change 1B with the same ID of your music

6 Save


You can find all the music IDs in the Tools/Options tab of NSMBe

Where are the graphic files containing the "World X-X" thing located?

There are multiple files you need to edit. All of the files are in the folder uiStudio.

Hello again community, I just download the nsmbds save editor onto my computer so I can unlock all the exits/worlds. I followed all the procedures and loaded the .sav file into the editor. I unlocked all the exits/worlds on the editor and put the file back into the micro sd(I'm using an r4). Whenever I load the file on the game that I'm playing, I get a black screen and the game freezes. I don't think I'm doing anything wrong but if I am, can someone plz help. Thx.
