I'm surprised that NOBODY over the years has ever made a save editor for this game. Well, now there is! NSMBDS SE can edit all 3 files in the game with the following options:

Life Count
Coin Count
Star Coins
Score
Mario/Luigi's current powerup
Inventory item
Bottom Screen BG

It can also unlock all the worlds in the game, as well as all the levels. (Be warned, as unlocking all the levels without unlocking the worlds first results in some small weird things that occur on the worldmap!)

How to use? Dump a .SAV file. (currently no support for other save types) To get your .SAV savefile, you can choose 'Export Backup Memory' in DeSmuME, use TWLTool on your 3DS with homebrew, or however else you wish/know how to retrieve a .SAV save from NSMBDS.

You can download v1.0 right here:
https://github.com/newluigidev/New-...tor/releases/download/v1.0/NSMBDS-SE-V1.0.zip

Oh and, thanks to these awesome people for their help!

Holy crap we can get custom bottom screen images?

You rock dude

Edit: Read this wrong, seems this might not be the case. NSMB is still among my top 3 favorite games, so I will be using this a lot. Thanks for making this!

Hi, I'm not sure how to open the .SAV file on the save editor. Is there a certain place i have to put the file in order for it to work? I'm probably missing something really simple here like a big ''Open File'' button :P

I've cleaned up the code and fixed a bug, and plan to add some features.
I don't have a pre-built release yet, but the code is at my github repo, SuuperW/NSMB_RNG/NSMB-Save-Editor. (I can't post the link since I'm a new user, apparently.)
