(PS2) Sakura Wars

Post by simon »

Seeking text files for Sakura Wars: in Hot Blood.

The main file is 00_BLANK.DAT, but it's a gigabyte in size, so I used filecutter bms

That gave me 2 files, 00_BLANK.DAT_0_1182793728
and a second file that has 1180696576_ before the 118

However, when I read them in a hex editor, they seem to be partially encrypted or compressed.
I can read some of the Japanese characters, but not all of them.
I have the ability to read the Japanese language.

Under the name Sakura Wars: in Hot Blood. you most likely mean the game Sakura Taisen Atsuki Chishio Ni

00_BLANK.DAT This is not an archive and there is no encryption, every 8388608 bytes are repeated many times, it's just random bytes.

The text is in the files. SMX it is encrypted with XOR 1 byte FF, the data is compressed by the SEGA PRS algorithm
Here are the unpacked .SMX files and my script for unpacking files written in Python 3.4 https://yadi.sk/d/VepMeDOq3WLURh
