Senko no Rondo 2 arc format

Post by Someone12 »

Hi.

I want to get into this game's gallery art and extract them but the problem is its in a Arc format. I tried some other methods and tools out there but nothing worked. Could I have some help with this?

It's just a pack of zlib compressed files. This BMS script should be sufficient to extract your files:

Code: Select all

comtype zlib_noerror

get FILES long

for i = 0 < FILES
   get OFFSET long
   putarray 0 i OFFSET
next i

for i = 0 < FILES
   get ZSIZE long
   putarray 1 i ZSIZE
next i

for i = 0 < FILES
   getarray OFFSET 0 i
   getarray ZSIZE  1 i
   goto OFFSET
   get SIZE long
   reverselong SIZE
   savepos OFFSET
   math ZSIZE - 4
   string NAME p "%05d." i
   clog NAME OFFSET ZSIZE SIZE
next i


The extracted files is a DDS image which you can convert it with tools like XnViewMP.
