Nekopara xp3

Post by huehuehue »

can someone extract .xp3 from the game Nekopara
this is the sample file http://www.mediafire.com/download/pvuxz ... vimage.xp3

unfortunately mostly the xp3 extractor i know doesn't work on this one because they are using KiriKiri Z https://github.com/krkrz/krkrz :)

Bumping this because I'm also interested. Here are two more samples: http://*USE_ANOTHER_FILEHOSTING*/c79e9a3 ... ara_xp3.7z

Basically it extracts just the PNG files because the SCN and KS have the first byte invalid (if you know this byte, let me know):

Hm, there's a problem with the XOR. Here's a sample to check it with the ogg files: http://*USE_ANOTHER_FILEHOSTING*/f1888ec ... ata.xp3.7z
Thanks for helping out.
