Me & My Katamari(PSP) - sample files

Post by AnonBaiter »

Here are the samples.
The strbody.bin file has stored filenames before the actual data so when extracted they should be set to .npsf extension instead of .nps. I suggest this solution because it might be possible to detect the offsets based on the "NPSF" sign, but I don't know.

And here's one NPSF archive file from Ridge Racers. I couldn't upload the other one(RRP.DAT) because the archive has zero references to the offsets.

Ahem...

Code: Select all

- open input file E:\No-Intro\Sony - PlayStation Portable\0001_RIDGERACERS\PSP_GAME\USRDIR\Data\Sound\bgm_nps_pack.bin
- open script E:\quickbms_scripts\npsf_ps2.bms
- set output folder E:\No-Intro\Sony - PlayStation Portable\0001_RIDGERACERS\PSP_GAME\USRDIR\Data\Sound\bgm_nps_pack
- the folder doesn't exist, do you want to create it (y/N)?:
  y

  offset   filesize   filename
--------------------------------------
  00000000 373000232  0101_mega_high.ss2

- 1 files found in 30 seconds
  coverage file 0    99%   373000223  373002240
  coverage file -1  100%   373000232  373000232

It just dumps the whole archive, and although the result file is audible, it's not the result I was aiming for.

NPSF not archive, audio file. Script convert it to ss2 > output file can be playable with Winamp and vgmstream or MFAudio

Ahh... but first I have to split the NPSF files from the .bin archive file(do I need to upload the full .bin archive?). I'll have to test another script of his(generic splitter) first so that I can test that script with the resulting files later, but the .npsf files are supported on-the-fly by vgmstream so...

EDIT: Nevermind, problem is solved by trying the "Advanced Cutter/Offset Finder" on vgmtoolbox and adjusting a few parameters. Thanks.
