Hello!
Despite the title of the game, I'd like to add it to my VGM collection. It uses the insomnia engine and I extracted the files nicely with Luigi's script. However, the audio files use a custom audio header. While I can write a script for PCM 8/16bit, I get a problem with WMA. I've uploaded a sample for each variant and I'd be happy if somebody could provide me with a solution for the WMA streams.
Here are the samples: http://*USE_ANOTHER_FILEHOSTING*/d00baaf ... tts2015.7z
Thanks for your help!

I don't have idea of what should be the format for wma2 in this case.
But I used the same script of pcm with the wma file and probably with some modifications it's possible to open it with mplayer/ffmpeg because it understands that it's wma2 (so the codec field is correct).

Yeah not much useful, anyway this is the simple script I used:

Code:

get CODEC short
get CHANNELS short
get FREQUENCY long
get SAMPLES long
get DUMMY short
get BITS short

savepos OFFSET
get SIZE asize
math SIZE -= OFFSET

get NAME basename
string NAME  = ".wav"
callfunction TOWAV 1

startfunction TOWAV
    set MEMORY_FILE binary "\x52\x49\x46\x46\x00\x00\x00\x00\x57\x41\x56\x45\x66\x6d\x74\x20\x10\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x64\x61\x74\x61\x00\x00\x00\x00"

    set RIFFSIZE long SIZE
    math RIFFSIZE  = 36
    set BLOCKALIGN long BITS
    set AVGBYTES long FREQUENCY
    math BLOCKALIGN /= 8
    math BLOCKALIGN *= CHANNELS
    math AVGBYTES *= BLOCKALIGN

    putvarchr MEMORY_FILE 4 RIFFSIZE long
    putvarchr MEMORY_FILE 20 CODEC short      # wFormatTag: Microsoft PCM Format (0x0001)
    putvarchr MEMORY_FILE 22 CHANNELS short   # wChannels
    putvarchr MEMORY_FILE 24 FREQUENCY long   # dwSamplesPerSec
    putvarchr MEMORY_FILE 28 AVGBYTES long    # dwAvgBytesPerSec
    putvarchr MEMORY_FILE 32 BLOCKALIGN short # wBlockAlign
    putvarchr MEMORY_FILE 34 BITS short       # wBitsPerSample
    putvarchr MEMORY_FILE 40 SIZE long

    log MEMORY_FILE2 0 44 MEMORY_FILE
    append
    log MEMORY_FILE2 OFFSET SIZE
    append
    get RIFF_SIZE asize MEMORY_FILE2
    log NAME 0 RIFF_SIZE MEMORY_FILE2
endfunction

Ok, as far as I got.
Can anyone help me with the needed ffmpeg options to decode the file? Any possibility to modify the header to wma so it's playable?
