I wonder what is the comtype of this game.
PPHD, PPTN, PPVAH, KSEF0130,... - maybe uncompressed
TK5P, CMPS - some TK5P may uncompressed, but most of this type seems compressed

Data file https://drive.google.com/file/d/0B8iw-j0BGWKIRHU4RGN3YnFNVzQ/view?usp=sharing

Code:

#Extract tk5 from Taikou_Risshiden_V DATA.BIN

endian little
math files  = 6688

FindLoc OFFSET string "TK5P"

for i = 0 < files
goto OFFSET
getdstring SIGN 4
get UNK1 long
get UNK2 long
get UNK3 long - SIZE..?
get UNK4 long - SIZE..?

if UNK3 != UNK4
math SIZE = UNK3

log "" OFFSET SIZE
FindLoc NEXT_OFF binary "\x00\x00\x00\x00\x00\x00\x00\x00" 0 ""

else
FindLoc NEXT_OFF binary "\x00\x00\x00\x00\x00\x00\x00\x00" 0 ""
xmath ZSIZE "NEXT_OFF - OFFSET"
log "" OFFSET ZSIZE
endif

FindLoc OFFSET string "TK5P" 0 ""

next i

I suggest you to find the index file because it will make the whole work easier.
A scanner must be just the last hope.

The compression scanner works at 100% when you know the exact compressed size of the input file.
I tried it with a CMPS file but I had no good results.

Unfortunately, in the USRDIR folder, there is only one file, Data.bin.

Are there any cases, eboot files hold index information?
Here is decrypted eboot file. https://www.sendspace.com/file/fcipw3

Code:

open FDSE "data.bin"
open FDSE "boot.bin" 1
goto 0x3cb0b4 1
for OFFSET = 0
    get SIZE long 1
    if SIZE == 0
        break
    endif
    log "" OFFSET SIZE
    math OFFSET   SIZE
    math OFFSET x 0x800
next

Regarding the compression used by the CMPS files, I don't know what should be their content.
There is a certain huffman encoding (bcl_sf) that gives something like a bitmap, I mean just the output data in the hex editor and not a real image.

Thanks a lot.
