NSwitchDebugger tutorial
original post
The goal is to check addresses until we find the correct one with the value we want to change. we do this by starting game multiple time and with process of deduction we can find it

prerequisites

• SDfiles V521
• NSwitchDebugger_v0.5.8.zip
  
• CTCaer Mod V3.2) - Hekate (payload)

Download above file

1. extract SDfiles to your sd card (if you already have latest hekate skip this step)
2. extract NSwitchDebuger to sd card overwriting files
3. enter RCM mode and select "NSDebugger"

Once in game note what items you wish to edit (coin count) then hit home

• Start homebrew menu and run NSwitchDebugger

Spoiler: image

• Now use UP and Down to select the game by title id
  • flip threw until you see Application name where it says Apllication in image

keep in mind a game may have multiple processes running you may have to try bellow a few times until you find results​

• Hit A, should show Success

Spoiler: image

The next screen will appear

Spoiler: image

• If you know the address this is where you would enter it...
  • Also if you see below We are our of range

Spoiler: CODE

• We dont know the address for this guide so we will need to search for our value
  • note: we now need to know how wide are the offset is lets say we are editing coins we note that coin count can go up to 9999999 so we use 8 bytes, lets say we are editing a item that can go up to 9999 so 4 bytes, 99 would be 2. we would change between them by hitting L and R

• Hit X to search for value so lets say we are editing 1234 coins in SMO

• use L and R to change byte size 2,4,8) use d-pad LEFT and RIGHT to move between digits and UP and DOWN to match 1234
  • it is easier to hit d-pad left a few places to change numbers to higher values instead of going from 1 to 1234

Spoiler: image

• Now hit A to do the search

you will see below as searches through addresses

Spoiler: image

If you only found one or two offsets you do not need to exit and restart​

• After the search hit home
  • we will now spend coins and re-search the stored offsets from prior search

If you find more than one addresses you will want to open game again and spend a couple coins re-search with Y.

• Restart nswitchdebugger repeat above but hit Y instead of X to repeat search
  • this should narrow search down to a couple or one hit
• If you still getting many hits open game up again and spend more coins and re-search again with Y

When your search is done and narrowed down it will take you to first found address hit (hit L and R to change addresses if multiple hits). Now we can do our edit
(I was only looking for number 1 for this screenshot to write this guide, assume I spent 1233 coins)

Spoiler: image

• The following is now where we do our value changing
  • note: write down the address listed as you will use it in future to do this mod without doing the whole searching method
• We will now press A to change 4D2 to 5F5E0FF (again for guide i did 1 to 2)

we will now see bellow​

​

Spoiler: image

• press up or down to change number left or right to change column
  • note: we can also change byte size here but keep in mind this could break game if writing back a too large value

Spoiler: finished

rinse and repeat until you see your coins in-game change, continue the same for other values to get the result's desired

Here is a Video Tutorial



Congratulations you have now patched memory, Enjoy!

A whole heart has four parts, therefore the value 4 for a heart. 51 = 12 3/4 hearts

 

[dsrules]

I honestly dont think so as the app doesn't stay running after exit it basically just patches memory with new value

--------------------- MERGED ---------------------------


BTW what was the offset for hearts in zelda and if you dont mind can you report any others you find so I can update OP with them.

there are few .txt cheat files in the cheat folder, maybe that's for auto enable cheats???
I couldn't read the v0.5x.txt in the zip

good eye, I'm looking into it. The only way i would be able to figure it out would be to load one of the titles and see what it modifies. i can only make sence of a couple items

_title ƒXƒ^[
_enable
_s0
_size:3229000
_type:5
_perm:3
_offset:24D5DD0
_val:63
_vals:2
_end

ill have a look to see how to set up, ive only booted sx cfw using pro dongle to boot games and thats it.

it works fine with external payload from sx menu for nsp games you have installed, the the app always tends to freeze for me (5/5 times) during searching, but I only tested with one game

 

[Diavol0]

Someone can try this on Disgaea 5 ?
(i'm not a nps fan)

How did you make it work with Sx os file on SD? (kip,ecc..)

it's nsp, no idea what are kip,ecc
just follow the tutorial but boot external payload instead of sx default

yes, but you dont cheat in online games you will get banned and ruin others experience

Right

I couldn't get it installed, I followed the tutorial as well as I could but some of that hexy talk lost me​

Edit:
Problem: Freezing game, black screen in nswitchdebugger.

This was fixed by completely wiping everything off the SD card including downloads, putting just the sd files 5.2.1 and nswitchdebugger and checkpoint back on the system. Then I downloaded my games overnight. I don't think it's a bad SD card (Samsung EVO 256G), or rather, I hope not. Just a clean install of _everything_, and it all works again.

 

[aos10]

hmmm, everytime i enter homebrew after the game, the switch freeze.

 

[aos10]

i am trying using this on rajNX, and managed to narrow the search to 2 address in dead cells, managed to edit the first address but i can't choose the second address.

 

[aos10]

ok, i've edited the two address, when i return to the game, the value is still not changed, i've bought spend some cells, but still decreasing.
the way that i am using this app is open the game, then look at the value, press home and open the homebrew app, search until there is 1-2 address.
i've changed both, back to the game, but there is no change. maybe after the change it didn't save?

the final photo looks like this

 

[dsrules]

I think push A is for Write?

 

[wiitendo84]

I'm kind of having a problem as to it freezing when I select my game. Botw cartridge. Like it starts to load the game but freezes on the switch symbol at the bottom right. I am on 5.1.0 so will that be the cause?
