[supwang]

I got these files from the biggest nac.

academy
adventure
arcade_select
bigbang
...
system
...
vib

no, not with a text editor.
you need to edit it with an hex editor like HxD

I can't seem to find the title ID in the main.npdm
How did you manage to change it?

 

[thequickbrownfox]

Save works.

Really? After restarting console? Did you do anything else other than tutorial? Absolutely no errors?

 

[Zumoly]

But does it overwrite the SMO save?

Backup your save with Checkpoint first before attempting this!

A fucking lot of errors. My switch shutdown after doing something else of playing the game.

you have to store the title id in that file in little endian mode.

i'll quote myself:

Sorry but i really don't get this one step.

I use HxD I want my switch to load Axiom Verge when clicking Stardew Valley.
I've got both title IDs of the game. Can't find the Axiom Verge Title ID in the main.npdrm trough the search field

 

[scionae]

what is your original title id?

of puyo puyo? 0100F3D001DEE000

 

[jimmyj]

not very good with hactool how can I gtet exefs and romfs?

 

[Thetoto]

I think the SMO save and Isaac save are both on this folder.

edit: i have misread your post, sorry.

i'll quote myself:

Thanks! But I guess I did some more mistake, my game stuck on the "nintendo Switch" logo. Mario Kingdom Rabbits. But it starting now. So I would say : Proof of Concept working

Convert to little endiam and use the last bits first.

TX crying now

Not when they have drag and drop and save states they arent

search for 00E0DE01D0F30001 with HxD

of course, the new title id you're going to patch has to be in little endian too.

Found!, now?

Found!, now?

overwrite that part with your new title id (again, in little endian )

 

[Darth Meteos]

I think the guy wants to know what little endian is
