I'm deleting it. I'm sorry I didn't know

Sorry, sorry. I didn't know. Well gbatemp was fun while it lasted.

You can probably find what you're looking for on that iso site

well thank you. I would delete my message, but I don't exactly know how to do that

Don't worry, you won't get banned after one error just like that.

Nice I want to try this

TBH, there isn't much you can do with this. It's just colors, and text.

And texture if you know how. I could never find an explanation on how to do that.
I did it once, should probably go back and do it again with updated colors and text.

Well having email/phone number in the power off screen is a very neat idea

You can do textures as said above. I saw a texture for DS carts that made it have the R4 logo on the back of the cart.

IT WORKED! The order in which error messages appear isn't consistent on my systems but eventually I got it to work after trying several variations of your method. Thanks again.

That’s awesome! I don’t have a dev unit, but I might make mine say something similar just in case. I had a 3DS stolen from me once before... Something like this would make it worthless to pawn off.

Just some advice for people having trouble with it only extracting SystemApp and nothing else:
Right click Part1.bat and edit it. You should see SystemApp.0000.00000082. Change 82 to 83 and then run the batch file.
If that still doesn't work, try changing the number to 80, 81, 84, etc.
You also need to do the same for Part2.bat
Just something I thought to say because I was having trouble with it for a few seconds.

It may be something else for others though. Just attempt part1.bat, wait for it to error, look for the SystemApp.000.0000008x in the directory, then change the bat files to match that file

Ah, yes. I forgot to add that. I'll edit it just in case.

I could modify the batch file to pause and grab user input for the correct file

Speaking of "having trouble", I just bricked my 3DS. I accidentally installed the edited home menu twice. Thankfully, I had my NAND backup ready so I got back in.

Just think there was a time when we didn't have brick protection on sysNAND and people would accidentally (or just stupidly) do it on sysNAND and brick their sysNAND.

I wasn't around in those times lol. I hacked my 3DS, accidentally updated and got rid of my homebrew, and just left it alone until I found out about seedminer recently.

Currently tested and working on my end, but your mileage may vary.
Decided to fix up the batch files in OP to prevent the unecessary editing of the batch file
But I've made changes to the Part1.bat to search for the correct file to use rather than just assuming which one it is, and then handing that off to part2.bat as well.
Should fix any problems with those files.
Also did some commenting on everything I've done inside it.

Also Posting the source here in case someone thinks it's dubious:

If you encounter any errors let me know!

May want to add this to OP @Asia81

Edit: Fixed up a few things, namely comments that mentioned previously-used test variables instead of what the actual variables were.

 

[bungboi]

One more thing, has anyone else noticed that the eShop is prompting an update after doing this? Is it trying to restore my home menu?

If you follow directions in OP at this point, you end up downloading an old version of home menu because I don't believe OP has the most recent versions.
I would use godmode9 to dump the title .app to cia straight from your 3ds.

Updated the batch files a bit more to fix a few more problems, and to now support drag and drop with any CIA file name onto Part1.bin
Just running Part1 normally will use the HomeMenu.cia as done before.
