Well sadly it isn't signed with the 78 thing. But that's probably because they used a default quality of compression and just removed the signature. The data is definitely compressed though, looking at it there are no 0s or anything. Now just to look up how zlib compresses. Thanks for that though, i...

Thanks, I'll look into that. But when I say I know nothing about compressions I mean nothing <_<. lol, I guess it's never too late to learn.

I've been looking at the RE5 arc files and managed to figure out the container but not the compression. I've been told it's zlib, but I don't understand compression. If anyone could look at it, it'd be greatly appreciated. http://i233.photobucket.com/albums/ee309/jamesuminator/arc.png Main Header: P...

lol, cool. I personally think C64s should be used more often in University CS courses. It would help new programmers to limit their memory usage and what not. It would be great for game programming ^_^. This is really cool. Wish I had a C64 :(.

Java programmers, never trust 'em.

But yeah, this format is really simple. I just came in to say that, lol.

oh lol, fatduck. I was just joking about it being a zip file. I didnt' even look at the files lol.

lol, yes like a big zip file. But it is not zipped using a zlib compression most likely. I just came here to say, when you want to split a file use a hex editor. Get "Hexworkshop" as it is the best one (in my limited experience) there are many magical ways to get it ^_^. Using a hex editor...

hey ;D

I do believe we've met on darkmatter ^_^.

Sounds like it's compressed almost. It seems to be by the way you're describing these "Batch" instructions. The indexing method (palette) is very common, used in TGA & TIM2 to name a few. I would say it seems odd, but as you say, a decent way of rendering for the engine. It doesn't sou...

lol, that progress is me too ^_^.

I assumed the archives were just DRs. Theoretically they are, just compressed differently.

Odd, it should let you register :\
I'll talk to mario about it.

Interesting job there, I hope the compression isn't too hard. I've never had any experience with compression, so I'm clueless. I hope someone figures it out :)

Really? I only assumed it was Zlib because the arc container seemed exact to Dead Risings (both made by Capcom too). I don't know anything about compressions though, so I'll take your word for it :P

yes, same was happening to me. I couldn't properly compile zpipe.c :(. It's really odd actually O_o, I've gotten all the official header files. Maybe someone can rewrite the decompressor :\. The extractor still works as it's the archive contents that are encrypted and not the archive itself. :\, It'...

/dev/ cracked this down at http://darkmatter.de-coder.net (mario's website)
It's meant for DR, but it works on all X360 arc files.

it's just a zlib compression container. nothing complicated.

I think I mean fixed point. I wasn't aware of 1EEE bit O_o. I just mean: x = (ptr[1]<<8)|ptr[0]; return((double)x/65536); //double for extra precision. Yes I do mean that for the vertices. Perhaps it is triangle strips. I don't really know much about 3-d either. But I'll go look up what that is ^_^.
