Dungeon Defenders Compression Toolkit

[fairchild]

I'm using tellg(); to get the file size so that should not be the problem.

It works perfectly for me, this is what i did:

c:\test>dd.exe -d c:\test\DunDefHeroes.dun c:\test\save.decompressed

What's the output from the compress preceedure when you compress the file? Also if you have "gnuwin32" or similar installed, make sure you don't use the (linux)dd program as that is for copying data. In that case try rename my tool "dd.exe" to "dungeons.exe" and run that instead.

mine hangs here....



and it loops through the file creating infinite null bytes...i let it got to well over 100MB

That's what the problem was, I was adding the 1 at the end of save.decompressed lol It compressed it fine now :P

EDIT: Save freezes my xbox, even if I just change the exp...

EDIT 2: Even if I decompress the save and the compress it, it still freezes, even tho I didn't edit it... I don't think the decompression/compression is right???

Here's a debug build, it has more output when compressing and decompressing, might give me more info on where it fails and starts to fill the file.

Filename: dd_debug.exe
dd_debug.rar

Compression:

[Buddah]

lots of padding

lots of padding

Remove the "1" from the input file.

@Idlehands88: I'll look into the compression then, might be something in the header that needs patching or something aswell.
