ROM Hack 3DS .CWAV Dumper

I think the whole dump has to fit into your memory.

Yes, this. The file itself is loaded into a temporary buffer array while it is scanned. In essence, you have to have enough memory to hold the entire file in the ram for a few minutes, or as long as the scan can proceed. Once it's done, it unloads the buffer and uses a streamreader to access the file via offsets.

You could use a filestream aswell. That way it is not fully in memory.

It doesn't matter since there is swap.

I was thinking about that, so I'm thinking that I'll see if that's feasible in the scope of the application.

You don't really need to, since the unused stuff is kept in swap, filesystem access is more efficient tho.

So I need enough RAM to hold the entire rom?

Not right now, as roms can't be checked (There's no public decryption method), but for now, you have to have enough memory to hold the file you're scanning. I hope to improve upon this in the future though.

There are many ways to make this not so cpu-ram intensive btw...

What is actually the problem. Everyone with windows 7 got at least 1 gb of ram. It should just work.

 

[uyjulian]

Lol people are ignoring me olol

 

[MrCobblestone23]

Could someone make some more dumps from mk7? That would help me a lot with my cgfx viewer.
I got piranha plant pipeway already, and I would like to have shyguy bazar and daisy hills.

Would you be so kind to upload that specific track somewhere? It would be really nice if you could do that .

The dump of Piranha Plant he's talking about is mine.

Oh sorry, I didn't know that. So did you upload your dump already somewhere? Since im not able to dump for myself, I would really appreciate that.

Because in the future, when ROMs can be scanned, good luck trying to fit a 2GB rom into 1GB of RAM.

 

[soneek]

We'll probably be able to browse the file tree at that point. And buffer sizes can be used when scanning large blocks of data anyway.

page files!

I know this wouldn't be an ideal fix, but it'd make the program function as needed, or just throw a disclaimer that openly states you need at least as much ram as the size of the rom that's being loaded...i know 1gb was stated here, but vast majority of people should have at least 4gb by now....

Yeah even shitty laptops bought at wal-mart have at least 4gb of ram.

Team Fail, into RAM dumps there are other informations: for example pattern lock code (1234 ) or nickname. It´s possible you to extract this data from a ram dump ?

I'm interested in this as well, mind sharing?

So I have some really good news, guys. I might have access to a 3DS with firmware 1.1 installed on it, however I am $50 short. I'm currently attempting to collect funds (Selling stuff), but if I get anywhere on this, I'll be sure to let you all know so I can start working on researching other audio formats.

Edit: I have gotten the funds from selling things, I'm trying to get back in contact with the seller so I can get the 3DS. I plan to have it by next week, and I plan to be dumping and researching audio by the end of next week.
