block unpack system.mrs

[devilcurse]

How can i block the unpack from the system.mrs??
Please help!!

Well, there's a number of methods you can follow to approach this problem.

Personally, I recommend the FU method, involving a very simplistic approach. By deleting the system.mrs file, all such data can not be retrieved, or further unpacked; as you cannot unpack what you do not see.

Delete it. Delete the whole damn thing.

Delete it, and then they can't unpack it.

Now for serious time. Impossible. Everytime gunz runs it nees to unpack the files to read them. It unpacks it to memory, which can then be read. If you block it from opening then you block gunz from opening it. Sooooo. Fail? It is theoretically possible for gunz to be forced to read only certain parts and when done automatically unload them. 1. It would be next to fucking impossible without the source. 2. HOLY **** MOTHERFUCKING LAGG OF GODS.

You're right on one part, the files always need to be read. They don't, however, need to be stored in plain text. Hooking the MZip functions would be all you would need, no source is needed here. And no, decompression of files isn't always slow, you'd probably not even notice it.

Yeah its not impossible to make your .MRS where people cant download your client, and unpack your ****, and take it. You can turn your .MRS files into XFC files, but im not sure how, ive just seen it on some Private Servers

(When I say steal your ****, im talking Models mainly ^^ )

<name>.XFC is just changing the extension name, its the same thing as a .mrs. Its useless.

The way I like, is the way Someplayer codes the Epic gamers launcher. It dl'd the .mrs files from a source, unpacked them to read, then launched. The .mrs files aren't actually on your computerl

 

[mwill14]

Oh lmao, wasnt aware the MRS unpacker/Packer would work on XFC, which is why I thought that would work T_T

I don't think it does, but its just as simple as changing the extension back to .mrs

 

[mwill14]

Oh really? ahhhh dam lol Thought you would have to actually get a converter for it or something.

Didnt think it was as simple as a Name change, rofl

/Fail on my part

Not to mention, once the files are interpreted, some files, such as zitem, can be removed from memory.

Yeah, except you're wasting hundreds of megabytes of bandwidth per load.

I know it takes more space. I just like that idea. IF you can afford to use that space and make it load quickly, id say do that.

 

[Wucas]

couldnt you just have gunz load the files located in system.mrs on load? i mean really, its less then 2 mb. Keep the graphics files located on the clients computer, but keep the system information on the server

Bandwidth not disk space; and, having only the system.mrs file sent over a stream and interpreted works just as well.

True, I was thinking moreover of making model and stuff safer.

And by space, I meant Band with.

Yea, or the file could just basicly be encrypted and can only be opened with a decrypting system or just a good mrs unpacker.

it it is a md5 hash check then i'll suggest your way, but keep it easy for these kids around the net they don't even know what "approach" is.

"Bandwidth" - one word.

That's what's currently done, except the encryption scheme is well-known.

An MD5 hash "check" of what? The files? Currently, CRC32 is used, but a truly secure scheme would involve a SHA1/salt checked on loaded files concurrently during gameplay.
