ROM Hack I don't understand how to make proper use of HANS, aside from region, spoofing, etc.

How do I make custom code to load my games with? I've never seen any sort of 'code'. I also couldn't find anything on Google. Romfs also confuses me in general, but that's because I lack knowledge on hex editing. Speaking of which, where do I start, and what do I learn to be able to use hex editing on 3DS titles? I want to contribute to the community and this is my perfect opportunity. Sorry if I'm somehow being dumb one way or another in this post, but I really want to make some interesting stuff for people to try out with this new application.

romfs = romfs.bin
code = file within exefs.bin

you have to dump them or obtain those files before you can even do any edits

romfs is basically the filesystem of the game
code is the main game code that is run

to make edits to your game you can edit either of these two files.

romfs has to be unpackaged to the individual romfs files (via ctrtool or etc), then you can edit individual files. Dunno if HANS wants a single romfs binary or would want the unpacked files.

Thank you! However, I'd like to know how I can edit the romfs. Is there a limit to what I can do with them? For example, could I edit the Smash 4 engine or something along the lines? There's a lot of stuff I'm interested in...

I'm studying hex editing right now, it's very simple. I just edit the code, correct? Is there a good program for editing code and/or romfs?

where do you place those two files again? Have one with custom Smash music and wanna test it out.

romfs/code is essentially the whole game; you can do whatever you want.

'I just edit the code' is vague, you'd need documentation on certain game structures before you make edits, or else you'd crash the game. If there is no documentation, have fun figuring out those things

HANS tells you where to put them.

How can I run Neo X and Neo Y on HANS?
The RomFS supplied is split into parts..?

I need a ton of help. I don't even know where to start.

If you can't dump your ROM on your own, just wait for a while for more information to be posted by other users.

Is there anything I can do productive right now? Like...what will I need to know when I begin making ROM hacks?

Where can i even get hans?!, i've been searching for hours

i got it smealums the homebrew starter pack

 

[hacksn5s4]

smea should add a rom dumper to hans to people can make hacks easeir

Yeah the problem there is all rom dumpers (only one homebrew one that i know of, Uncart and then of course gateway menu and clones) seem to run on arm9 which obviously isn't (publicly, who knows what's possible behind the scenes) possible on 9.3 and up (yet).

So it isn't as simple as just "adding a rom dumper"....

If I'm understanding this properly, HANS has nothing to do with the RAM of the game? So it's nothing like NTR? Any "codes" would be directly modifying the game you're playing, not changing what's being read by the game?
