Unhappy TVP KIRIKIRI 2 core game hacking help

I'm trying to extract data (images, scripts, etc.) from a chinese doujin game (kirikiri2), but it isn't going very well.

This free fangame, when downloaded, is a 95.6 MB executable that comes with no other files. Obviously, the xp3/archives data I'm looking for is embedded in it.

I have no experience dealing with games that have their xp3 embedded in the exe, but I tried to use my trusty xp3viewer anyways. All I get is a "savedata" folder with .ksd files in it (specifically: "datasc.ksd", "datasu.ksd", and "data999.ksd"), and nothing else. The usual xp3viewer window that pops up doesn't appear, either. The game runs well, though.

I'm not really sure where to go from here. Could anybody please point me in the right direction, and tell me which tools to use instead? And if you think I have to resort to using a hex editor to get at the xp3 embedded in the exe, would you please tell me how to do it?

If you must flame me for being a greenhorn then I wouldn't blame you :(
But after burning me alive would you consider helping me anyways? I've got a bad track record of getting insulted with no real helpful comments.

Thanks for your time!


ADDITIONAL DETAILS:


- English is not my first language, so I'm kind of rusty. I'm terribly sorry for any weirdly phrased sentences in this post and I'll be happy to clarify anything.

- The chinese doujin game I'm trying to extract data from is an otome game (a prequel, to be exact), and was released in early 2013. There were several separate attempts to get at the data in the past (to make korean translation patch and an english patch, I believe) but I wasn't able to contact these people.

- I recently attempted to use the kirikiri splitter/merger tool on the game's executable. It tells me that it failed to locate the archive offset.

- I'm going to try extracting the data from the game with crass because I heard it was as good with excrypted archives like xp3viewer, but because I'm a noob hacker I would really appreciate it if somebody explained how I'd go about using crass (or any other tool) to tackle the game.

-The game in question is "月华", or "Yue Hua" an otome fangame based on the "Gintama" series.

- I've only extracted data archives from two other kirikiri2 games in the past, and both instances were relatively straightfoward so I managed it myself with a little
Google-fu. So if I sound like a hopeless noob, that's why.



Thanks again for reading!

have you tried kikiriki?

open command prompt,
"kikiriki.exe -i <thegame.exe> -o game " should do the trick

and if it doesn't work/youve tried it already, and all else fails you could try asking for help from better experienced peeps?. specially if your trying to translate the game, i think there was an irc or a website you could visit instead? --don't quote me, i'm just going off what i remembr, i'm most likely completely wrong, lol.

he never SAID what he was going to do once he manages to extract the data.


but just in case he DID mean to make a translation patch, I'll recommend to the op to check out insani's articles on hacking to read. it sounds to me that the game's archives were... uniquely encrypted from each other? especially if xp3viewer managed to extract a savedata folder but nothing ellse. maybe??

I'll be sure to check out the articles, thanks!



Here's a slight update on my situation:

- Yup, I'm planning on making a translation patch for Yue Hua. And I also plan on editing the chinese text in the images, too, so I need to get my hands on all of the material.

- TimScampi seemed to have a similar dillemma in his thead in the Technical Issues section. And like Tim, I have tried to use insani's xp3-extract tool, and got a result very similar to his.
But... he somehow managed to solve the problem with ExtractData 1.11. Unfortunately, ExtractData (v1.20) tells me that the game.exe is corrupted/damaged.

- I was wondering: could this be more of a compression problem than an encryption problem?
