ROM Hack [Release]3DS Lazy

[loco365]

Rather curious, does your application have support for 0-Key signed roms?

 

[hackotedelaplaqu]

You mean roms xored with 00 ? I don't se why it wouldn't work.

Great stuff, but i have 1 problem, when i say yes to include the manual, it created no cia, when doing it again and say no, it creates a perfectly working cia
Also, I just need to wipe all folders created for creating the cia before starting a new one, but that's a minor thing

Converted all my own dumps to cia (over 20 games) all work flawless till now, converted a bunch of other roms to cia with 3ds lazy, never been so easy, just click and wait and click, click and done

I used to follow this lenghty guide, but i'll keep it for now as a backup, but since i use 3DS Lazy i didn't need to check on this.

Thanks for feedbacks.
Folders are not wiped after conversion because you may want to rebuild the same rom many times (eg : translations).

About manual, before the rebuilding process (but after decryption), do you have this file in xorpad folder ?
"manual.romfs.xorpad"

And those files in 3DSLazy main folder
manual.cfa
dlp.cfa

I get the "Could not read rom file". Any solution?

 

[Carnivean]

I'm not talking about FAT32.

Neither was I. You can't read more than 4GB into memory with a 32 bit exe and makerom loads the entire rom into memory while working with it.

Thanks for the answer,
manual.cfa, yes, dlp.cfa, no
manaul.romfs.xorpad, have to check next time and when i'm home.

[EDIT]
The Legend of Zelda Majoras Mask 3D

Perfect conversion (including manual), installing the created cia was without a problem!
Thanks again for this great, very easy to use tool for 3ds to cia

(I will not play it yet until friday )

You don't have a x64 processor right ? And your rom is bigger than 4GB ?

This happens on 64 bit processors and systems with >4gb too.

This was solved by another user :

on W7 x64 Solved, Virtual memory size UP

Cool, not a big fan of the fix as it requires a system reboot (I'm one of those people that keeps their machine running 24/7 for a few different reasons), but glad that there's a workaround.

EDIT: on an entirely different and unrelated note, might I suggest adding support for card2 based games, such as pokemon x and y (even if it's just tacking it in as a checkbox)? As of right now, this will generate a .cia file that will load, but promptly crash upon attempting to save. I know this can be worked around with other tools, and I'll probably go that route for the short term, but figured I'd throw it out there as an idea for future improvement.

I can build cia file with modified romfs content with this tool?

You could, but I use Auto_CIA for it

 

[Anton299]

but I use Auto_CIA for it

It doesn't work for me. AutoCIA didn't extract RomFS for me. It prints what it does at the bottom, but there are no -romfs romfs.bin, ever...
It builds cia with size about 3+ Mb (it's just ExeFS).

3DSLazy also doesn't work for me... I have "can't read exheader" (or something like this) message every time.

 

[dubbz82]

Two known working programs failing...I get the feeling some things wrong with the ROM/cart you're trying to dump.

You can try the following method:

01. - Download the package in the attachments
02. - Decrypt your Rom with 3DS Lazy
03. - copy the decrypted "romfs" folder into the "RomFS Encrypt"-Folder from the attachments
04. - modify your "romfs"
05. - Run "Use this to build a new RomFS.bat"
06. - you created a new romfs.bin
07. - Download and run Auto_CIA and decrypt your 3DS Rom
08. - copy your fresh-builded romfs.bin into the tmp-folder of Auto_CIA (after decrypting rom)
09. - rebuild your 3DS Rom with Auto_CIA
10. - You created a new .cia file (or 3ds) with your modified and rebuilded romfs.bin!

This worked well for me ,you can check my modified "Harvest Moon - A New Beginning" here:

I have all stuff decrypted already... Folders "romfx", "exefx" and exh[eader].bin file, rsf.file as well. I want to just build working cia from that stuff...
I've tried makerom GUI with makerom file which is 627 Kb (641 323 bytes) or so - it works for LoZ-OoT. But it doesn't work for LoZ-ALBW (for that game 526Kb-sized (574 478 bytes) makerom works, but after cia install no icon appears (no gift icon in CFW, and no game icon as a result), but ALBW still loads from DevMemu itself. Pressing "Home" button just hangs the game - only power off the console works to exit from the game.

Realy need a tutorial, what each parameter means, what's difference between tons of "makerom" files, etc...

Possibly wrong region / not regionfree?
This happened to me when I tried to install a game from another region

Both Zeldas are PAL.
My 3DS is PAL, too.

hmmm :/ don`t understand why it won't work
Where did you get ALBW?
