I'm Luigi Auriemma, I guess you know me as aluigi
and for my QuickBMS tool used to extract files from the archives of various games.
This is a "game research community" just like Xentax
but it's all free and with more freedom for both users and non-users.
Currently you can consider it a "complement" of Xentax but, who knows, maybe in future it will become even a real alternative
I work personally on various research topics and I can provide direct help on them, like archives extraction, compression and encryption, help to locate the correct script for a file format, QuickBMS scripting, tools written by me, some game internals, examples, some programming tips and so on.
Remember that this is a community and NOT a personal forum (like was the good old forum.aluigi.org
) so it's not about me or my help moreover because I can't dedicate much time to it.
In short: I pay hosting and domain BUT providing content is your work and your mission
If you like the forum and/or the idea, spread the word!FAQ and rulesWhat name is ZenHAX?
It's very simple:
- xentax -> xenhax = Xentax without "tax" and more "hacks"
- xenhax -> zenhax = the X was difficult to pronounce and "zen" is a relaxing word
Honestly I think that zenhax is a very nice name, short and can be pronunced easily What is ZenHAX?
A community forum regarding game file formats, protocols, security, information and other "under the hood" stuff.What is allowed to post on this forum?
The forum is about game research, so it's for things like the following:
What is not allowed?
- understanding the format of a game file
- extracting game archives
- everything about compression, encryption, obfuscation, encoding/decoding, conversion, extraction/reimporting and other algorithms used in games
- any other low-level information related to games like protocols and internals
- game security vulnerabilities and news related to game security in general
Anything which is:
Is it limited only to games?
- completely (directly and indirectly) unrelated to the topics of the forum (e.g. cooking)
- covered by other dedicated external forums (e.g. cheating)
- illegal (e.g. warez, botnets)
- advertising (e.g. "best SEO services")
No, any format of any software is accepted but games are the main software category to use custom file formats and "exotic" algorithms.
For example formats of some software and dumped firmwares.Is it free?
100% free and will remain free forever: no donations, no advertising, no banners, no strict rules, no private sections.What are the best ways/guidelines to post?
Be clear and synthetic, aka "go to the point".
A long post will be read by few people, others will give up because annoyed to read lot of useless text.
If you want to post information about a news or a tool, maybe add:
What's the policy about external links for tools and information?
- the subject of the information (name of the tool and target game)
- an abstract (files extractor or Steam voip vulnerabilities)
- the verbose or less verbose information with details
If available, post ever links to the official source of information or the homepage of the tool.
For example if you want to post a link to QuickBMS you will link http://quickbms.aluigi.org
and not an executable file on dropbox.Can I attach files?
Yes, there is plenty of space available. Currently the limit for each file is 5 mb but it may change in future.
When we review an unknown game archive we need to have a sample to review and so you can provide a splitted version of such archive.
There is a quickbms script to split files here
and one to rebuild them here
For big files you can use any file hoster like mediafire, sendspace, zippyshare, dropbox and so on.What are QuickBMS and those text scripts that I see in the forum?QuickBMS
is an extraction tool that works with some text files that contain the necessary actions for reading the format.
It's very useful because it already embeds many compression and encryption algorithms and all you need is just the quickbms executable and the script: no installation, no .NET framework, no Python/Ruby/Perl, no external dependencies, no compatibility issues, no bloatware.
And yes, it's open source, multi platform and actively supported by me.What's the best way to request help for a format?
Usually it's necessary the following:
- name of the game
- if you know also the platform it may be useful
- a small sample of the file in attachment or a link to file hosters
- if the file is smaller than 10mb you can just upload it entirely, otherwise it's better to split it with the filecutter.bms script seen previously
- an alternative to the sample is the image of the hex edited file or the textual dump of the hex editor
- sometimes it's just enough to post the signature available in the first bytes of the file, maybe it's a known format
The sample is necessary because often we don't have that game and so we need it only for research purposes.I have extracted the files from the archive and now how to read them?
Reverse engineering a game to mod it is a process composed by many steps.
First it's necessary to extract the files from the archives (my field).
Some of these files may have common formats like mp3, ogg, png, tga and dds, so there are no problems to open them.
Other files instead may have custom formats like images without headers, codecs that are rarely used or are customized, but the main problems are the 3d models because usually they require a big work of "tuning".
If you want to mod the game probably you need also the last step: allowing the game to read your content.
Sometimes the game accepts the new content outside the archives (maybe with a command-line option) while other times it's necessary to "repack" the content in a new archive.
My preferred method is the reinjection because it means zero additional work since QuickBMS already implements all the code that works with most of the game archives.
Anyway, as you can see, it's a long process requiring multiple skills and often the researchers are good only in some of them, basically it's a team work.
That's why it's necessary to have patience sometimes.Why nobody replies to my posts/requests?!?
Usually: people are busy and have no time to review or work on your requests.
Often: people have skills in specific fields and so they can help only on their fields.
Ever: people are not directly interested in that game/topic, the task requires too much time and effort, the information you provided are not enough.
I give you an example to explain the situation: let's say that you want to extract the files of game X and its archives are big, complex, encrypted, the game is not available for free/demo, it's an online-only game updated frequently and so on... honestly I would spend not even one minute on it if it's not a game that I own and like personally.I don't have a website and I would like to maintain a thread in which I provide my scripts, tools and research!
That's great! Open a thread in the Researchers threads
section.I have no programming/research/reversing skills!
It's not a problem, the community is made by people who:
- request help
- help others by making the research or finding an already public solution
- share their information and findings
- share useful information and links found on other websites to create a sort of collection
- write tutorials, videos, howto and step-by-steps or translate existing material in their language
- provide new ideas to improve the community: a wiki? a new section? a new phpbb mod? a new project? new features for a tool?
- spread the word about the forum
There is FOR SURE something to which you can contribute to, even asking help to extract the files of an unknown game archive is a contribution!Why there is a market?
Because on Xentax it's full of people willing to pay researchers for having some works.
After having evaluated that it's impossible to go against what people desire, I decided to provide a place where it's possible to ask help for tasks on which nobody was able to help for free.
Threads for selling stuff are NOT allowed.
Please note that any possible work and transaction between the users is just their business so the forum is not responsible (like people who don't pay or don't give the work or the work is horrible and doesn't work), consider that section only a space for announcements and nothing else.Why there are few people and posts?
What do you expect from a forum that has been just opened??? (August 2014)
But this is a community so there are lot of things you can do to contribute and first and most important one is: spread the word about this forum!
If more people are aware of this place then more people will join.
After all it's free and there are good chances that you will learn or teach something.Is it like Xentax? I LOVE/HATE Xentax!!1!
The forum is just like Xentax but hopefully here you will find what you love of Xentax and not what you hate.
Remember that this forum is NOT a competitor of Xentax or against them, I'm their friend and I'm there from years!.
It's just a way to cover all the things that are not covered there and those that are even unique (like game security).I would like to remain update about the forum on Twitterhttp://twitter.com/zenhaxWhy I get a white page when I follow your links on aluigi.org / aluigi.altervista.org?
It's a sort of leech protection of the Altervista hosting, it's enough that you click on the orange "qui" word that is displayed and you will access or download the file.
For your curiosity: what you see is "La risorsa richiesta è accessibile qui" which in italian means "The requested resource is available here".Regarding the Game security section: how to uze da *boom* tool??/? how can I patch my game server X against the *boom* attack?
That section is only for news and real new research.
I don't like the section X! I would like to see the section Y on the forum to discuss about Z
- no old stuff, except if it's still unpatched on new games or is quite recent (3 or 6 months max?)
- no help on using tools, proof-of-concepts and so on
- no help on patching servers and games against security issues
- no cheating: cheats and security bugs are usually called "hacks" in the game community but are completely different - cheats give a gameplay advantage while security vulnerabilities give an advantage against systems and users
Ok, send me your suggestions and we will evaluate them, maybe with a poll if they are interesting.Can I contact you via PM for the game X?
No, use the forum, there are more chances to receive support.Is the forum available also on HTTPS/SSL?
No, the old link http://ssl.zenhax.com
is no longer available on SSL.I registered but I didn't receive the registration email!
Wait 5 minutes and check the spam
It may even happen to wait a couple of hours to receive the registration email in some rare cases.
If you still see no email contact me at email@example.com
or with a message on twitter @luigi_auriemma
I periodically check the status of the inactive users so, in any case, you should not wait longer than one week.The website is down or very slow!
has some problems, then try http://backup.zenhax.comI have a question not covered by this FAQ
Send me a PM (user aluigi) or email or twitter.
