Taiko no Tatsujin V Demo (VITA) - .l7c

[DarkSynopsis]

Trying to look at the TnT V files and since the Demo is free its easier to get a hold of, looks like all the files are packed into "data_release.l7c" with the following header "4C 37 43 41" only other game I can find talking about L7CA is Tales of Hearts but it didn't look like it was successful? either way the QuickBMS script for that game gave me.

Code: Select all

  offset   filesize   filename
--------------------------------------
  02f83a00 3987       unknown_compression/_data/enso/renda/renda_effect_c_00.txp

Error: the script uses more array indexes (2917) than supported (651)

Last script line before the error or that produced the error:
  60  getarray ZSIZE      0 ID

Here is the file : https://www.dropbox.com/s/6x8utlgdzznzd ... .zip?dl=1#

Folder Structure/Files seems to be listed at the bottom of this file.

Edit: Ok checked the directory and I seem to have the renda_effect_c_00.txp, no clue if that is the complete file but its a start? leaves me hopeful can get all the files out.

It's one of "those" formats that is not clear and a solution working on one game doesn't work with other games or even other archives.
I used a workaround and now it seems to work with both games, script 0.1.1

P.S.: note that the names may not match at 100%, probably everything is ok but this is just an advise.

Thanks, works a treat at least for the files I was after though some have ended up in "unknown_compression" folder where as others that would have the same compression are not in there?

Now to work out what sort of compression is being used on .bin files found in the fumen folder, not LZ11 like the 3DS titles

https://www.dropbox.com/s/chvc2gq2w6k9a ... n.zip?dl=1

The above file contains

daybyd_e.bin = a .bin file from Taiko V (this game) that I want to decompress.
poly_e.bin = a .bin file from a 3DS Taiko title.
poly_e_decompressed.bin = same as above but decompressed, compression is LZ11.

I pretty much need to get the daybyd_e.bin looking like poly_e_decompressed.bin

Unfortunately I have nothing else to add about the compression of these files.
If someone wants to contribute, everything is welcome.

Managed to get a hold of the full game and even though its still a data_release.l7c file it appears to be missing any indication its a L7CA file and not seeing any file list at the bottom like the demo had.

I get the feeling this won't be possible but thought I'd throw it out there anyway, I don't know much about the VITA maybe this got dumped differently to the Demo version I got a hold of.

Edit: Turned out to be a bad dump.
