2009/06/30 / exsteldat

I'm surprised the obfuscation here got so much simpler.

I kept looking at the scramble algorithm trying to figure out why it does several operations that result in constant values ... finally I concluded that whoever wrote the code is just an idiot.

2009/01/31 / decrbrads

I should have recognized more quickly that the encryption being used here is identical to decrkansa, but that seemed so unlikely that I ended up reversing it all over again. I guess some game makers have been cut&pasting crypto code.

This tool only decrypts the archives; use exbrdat to extract them.

2009/01/29 / ar2bugfix

This tool fixes a crash, which many people have been wailing about, encountered when fighting Raki in the USA version of Ar Tonelico 2. NIS really made a mess out of the localization of this game ... there are other less deadly bugs, like the IPD contact text, that I might also clean up later.

Note that this tool is implemented as a scanner-patcher so that it will work with any target; run it against the game executable or any uncompressed disc image of the game.

Updated 1.01: This is a command line tool but I added a small delay so that novice users can drag&drop an ISO to it and have enough time to read the confirmation message.

// ar2bugfix.cpp, v1.01 2009/01/30

2009/01/25 / exar2

This can extract/rebuild RPK.BIN from Ar Tonelico 2 and also extract/rebuild the scripts (*.evd).

Script editting isn't terribly useful because text data is stored in several other places (including the *.ERX which seem to be executable overlays or something). But since I wasted some time looking at this I may as well release the tools and let people pretend they're going to redo the pathetic translation. Note that the scripts are SJIS text using wide-ascii(?) characters.

I suggest uema's iftm2 Susie plugin for the TIM2 (*.tm2) graphics since XnView screws up the color. Use bmp8to32 -fixalpha for correct transparency.

Updated: Added unlzr to decompress the LZR compressed data.

Updated: Added exar2fp to extract the *.fp archives (no rebuilding since I feel lazy). Also fixed a bug in unlzr.

2009/01/02 / exald

I've been wondering what the AJP are so I wrote a tool to convert them... if I had realized they are mostly animation junk I would not have bothered. This only converts the AJP/masks, so use Kouji's susie plugin or something else for the QNT images.

2008/12/29 / message board online

I missed having an easy way for people to comment and report problems etc, so I put up an experimental message board; feel free to post so it seems worth while...

2008/12/28 / exnpa updated

2008/12/28 / exmespac

For some reason they changed the graphic formats drastically, using different compression and muliple filtering algorithms. The delta filter mode is reasonable but the type2 one is ... extremely obtuse. If anybody knows the name of the technique, please let me know.

Updated: Apparently the strange algorithm is converting a YUV colorspace to RGB. The weights aren't quite the same though.

2008/12/27 / exlac

It seems like I've seen extractors for these archives before but it was easier to rewrite than find an old tool.

DDS Converter has problems with most of the graphics, so I suggest using XnView to convert instead. I hope ugly 3D junk like this doesn't become common...

2008/09/12 / don't send flowers yet

Since people have been emailing me, yes, I am still alive.  It seems a lot of time has leaked away while I've been addicted to Soul Calibur 4; it's way too easy to spend all night playing online. :)  Now if only the Xbox360's d-pad worked correctly...

2008/07/27 / exbsa

An old tool for this format wasn't working very well, so I finally got around to writing something myself. For some reason I thought it was a lot more complicated than this ...

I'm not sure if this will work for older games.

2008/07/16 / temporary page online

Seems like asmodean's reverse engineering page at Rakuten has become unavailable. Their site had become annoyingly cluttered with ads and other junk, so it's nice to have some motivation to move ... but since I am lazy now and want to play Persona 4 instead, this ghetto temporary page will have to suffice for now. :)

No comments or BBS yet. Send email to asmodean [at] hush.com or find me on efnet IRC.
