This system uses a variety of convoluted data structures and serialization methods. I'm not sure why, since the basic data access and layers of function calls surely make this much less efficient than simpler formats...

I have to admit, though, I've never seen anybody encode blocks within an image in different pixel formats.

I couldn't find the fragment offsets at first, so I actually converted the SLDT to something I could visualize and see if it described the offsets... That turned out to be a waste of time and I eventually found the offsets somewhere much more obvious. :P

Anyway, you can use merge_yatevt.pl to parse the scripts (*.evt) and generate various combinations. Where the scripts contains variables, it generates all possible combinations; pick the ones you like and delete the rest. And don't ask me about this, I didn't really care enough to waste as much time as I already have.

2010/06/03 / Visual Memory Add-In for Visual Studio

This is an Add-In for Visual Studio. It adds dockable windows which allow the user to visually inspect memory of the process being debugged.

Testing has been done only with Visual Studio 2008 on English Windows 7 and is at an early stage of development. Do not be surprised by bugs or other rough edges. Feel free to report any problems via email or my message board.

After loading this Add-In the Visual Memory windows can be accessed via a new menu added under Debug->Windows->Visual Memory. Up to four windows are supported.



See the included readme.txt for more information.

This tool decompresses most image data but I couldn't get the LZX data decoded properly. I think the XDK guys tweak this algorithm occasionally and it becomes incompatible. Anyway, it seems most of the interesting graphics data is ok. Maybe I'll take another look at the LZX data some day, but for now my eyes are tired from the nasty PowerPC assembly. So many registers and obscure instructions to keep track of...

This was irritating dealing with the block/delta image format, especially having to do so three different ways. Still, it's something I haven't seen before and was a bit interesting. The floating-point version I suspect is reassembled on the GPU, maybe in a pixel shader?

Usage of the merge tools is unusually complicated. The first parameter is the bitmap and the next is the delta data file (no extension). Passing auto where supported will guess paired filenames; it's usually right.

- merge_5bpfrag works with STEINS;GATE.

- merge_11ecfrag works with deltas in 11eyes CrossOver's chara.dat. Extracting everything will consume a *lot* of space.

- merge_11ecfrag2 works with deltas in 11eyes CrossOver's bg.dat. Note there are two bitmaps each for this one.

Apparently somebody is a fan of exotic algorithms. This format uses multiple block ciphers (AES, RC6, etc) and a tweaked implementation of SHA-256 for encryption. For data compression, it's using fancy Move-To-Front and Burrows-Wheeler transformations followed by custom RLE/LZ77 or Range Encoding. Finally, some images are compressed with a custom block algorithm that seems similar to JPEG without the DCTs.

2009/06/07 / d3dslide

I've been looking for a simple program to idle displaying images on my HTPC but nothing really did what I wanted. At least it was kindof fun learning Direct3D to write one myself.

This application displays an animated slideshow using a handful of effects smoothly animated using 3D hardware. The methods are optimized to always fill the screen (no black bars) and it tries to select methods appropriate to the aspect ratio of each image. In particular this does well against very tall images like magazine and stickposter scans.

A modern GPU with vertex shader 1.1 and pixel shader 2.0 is needed. More video RAM may allow you to use higher resolution textures. If you notice slight animation stutters sometimes during image transitions, try tweaking the MAX_TEXTURE_PIXELS values in d3dslide.ini. That can also be used to improve quality if you're feeling adventurous. :)

I haven't tested this on very much different hardware, so let me know how it goes. I am particularly interested in performance with very high resolution images (7000x3400 etc).

Updated 1.02
- Fixed a bug configuring the presentation method weights.
- Added a few new configuration options.
- Improved performance with large textures a little bit.
- Changed animation timing to be based on frames instead of real time; this makes it smoother particularly when dropping occasional frames.

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.

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.

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.

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.
