ROM Hack [Release] 3DS_CTR_Decryptor-VOiD

[Deleted-346555]

Can't promise anything but since this tool is clearly half finished, I will surely launch a v2. Can't say for sure but the 1st main features will surely be the anti-freezes and speed improvements(man this shit is SO slow)

 

[ghjfdtg]

Right, this code is a pretty half assed job.

 

[ultimatetemper]

Looks like 4GB roms doesn't work with this tool, I got an almost 1GB of a xorpad file and now I'm trying to rip the game music.

 

[Kakkoii]

.

Could a database of xorpad files for various ROM's be enough? We could build one that would be used for decryption tools on the PC so not everyone need go through the 3DS process each time for a game if someone else already had?

I guess that's true in a way. But if you do not have a 4.5 3ds, how on earth can you test your project?

Not everyone wants to decrypt simply for homebrew. Others, like me, merely want to get at the 3D models from games like Pokemon.

The method used to produce the XOR key is buried inside the CPU. It would require decapping and analyzing the chip.

And yet, so many of the "pros" on here kept saying the decapping would be useless...

 

[gamesquest1]

well sharing of xorpad files have already been deemed not allowed on gba temp, so whilst it would be possible to use them you would have to find somewhere else to do so

 

[moosehunter]

How do you extract the RomFS and ExeFS? All 3DSExplorer gives me is a file filled with zeros.

 

[piratesephiroth]

Yeah, there's no reason for hosting the XOR pads when they're just as big as the ROMs (and just as illegal).
You'd better host the decrypted ROMs already and save everyone's time.

 

[NCDyson]

I had pretty good luck opening the rom in a hex editor, going to the position indicated by 3dsExplorer, and copying the raw data into a new file.

I am guessing .psb is some kind of archive format, not sure what .m means (when I see such things on the DS and the like I usually think compression of some form).

Any chance of opening a few up in a hex editor and posting screens?

Sure.

Is this OK? Feel free to ask if you’d like to see antything else.

 

[ultimatetemper]

Anyone succeded on decompiling a 4GB ROM?

 

[Celice]

Is it possible to inject ROM images into VC releases now? We have working VC emulators for GB &GBC, GG and NES. Being able to inject anything would be the best.

smealum had already shown it is possible to swap the ROMs, just as it was on the Wii VC service. We just have to be wary of their emulators support and don't support.

 

[chrrox]

I tried dumping a 4gb rom and it stops at about 1gb worth of data.

 

[Deleted User]

Could someone uploads some pics or info on MK7. Pics like hex editor and files. Info would be header and type of decrypted dump files. Thanks.

 

[Baoulettes]

Same* I am following this thread especially for MK7.
I honnestly brought the 3Ds right at release for zelda but also MK and I never updated it (beside forced update by game) in waiting of the day we could inject custom course on mario kart :3
so any info would be precious , like I seen Ninty keep their old file format like SZS and variant of bmd(?)

 

[Rizzorules]

We can decrypt and encrypt roms or just decrypt them?

What about porting MK7 to MKWii. The current way is to recreate it.

Just decrypt. But if you watch this topic you can follow that process if people are doing it.

 

[Abcdfv]

I think it's just decrypt currently. Though reencryption is justa stone's throw I imagine .

 

[Baoulettes]

Or porting some MK wii track to MK7, Like rainbow road, bowser castle etc etc
Cause MKwii is fun but in my case I do not own Wii anymore and/or Wii U so my only way is to seek in MK7 file but I have no idea where/how/if possible to get that decompiled files without modded 3ds (I don't have gateway or anything ^^)
