After several days of headache I'm happy to present you new AE VN Tools build, now with full YU-RIS v4.90 archives and read-only YCG images support (they're named as .png, although the structure has nothing in common with normal PNGs, apart data compression (zlib)).
 
I'll add creation of YCG images only if there will be a need for this. Although it's not that hard (split image in half, compress each part separately), but I don't want to do extra work without a purpose.
 
P.S. The tool is only able to generate YU-RIS archives of certain versions, yet can open any version from v1.00 to v4.00 with no code changes thanks to my heuristics algorithm. If you need support for a particular version, please let me know (supplying the version number and encryption flag (0xFF or alike, see "Format" line in the GUI) will be enough).

Added support for YU-RIS v4.90 in AE. Details are here.

you can extract ypf files with other tools. then it is only a question if this one can read every text line. If not drop a name of a game.

I just want to get the word out there and drop this tool in here: http://progvian.wordpress.com/
currently only supports ypf 0.473

which are different games

Well, I can extract strings from them if its relatively new version of engine (my tools confirmed to work with versions since 400, and confirmed to NOT work with 2xx versions). Version is in header of each ybn file, next 4 bytes after "YSTB".
