Omega Five (XBLA) .paz files

Post by ChillyBilly »

Hey, guys. So, as the thread title indicates, I'm trying to rip the music for Omega Five for the Xbox 360, but I'm having trouble extracting the .paz files the data is contained in. Here are the files in question:

I inquired about this at another forum, and was told that the .paz files could be extracted with a variant of this bms, as well as this one, though the finer details need to be figured out first. So I was wondering if anyone could lend their assistance with this? Thanks in advance to anyone who can!

The suggested lzs.bms + add_pac.bms steps are correct but in this specific game it looks like there is something wrong with the decompression of lzs.bms because the obtained file.pac is wrong.
I have no idea why the lzs_unzip decompression doesn't work with it.

Even playing with the two settings of lzs_unzip (THREESHOLD and 0x1f/5) doesn't give good results.

Thanks for the response, aluigi! Hm, from what you say, it looks like extracting these files is a trickier job than I thought. I'll try finding my own solution if I can, but thanks in advance again if you or anyone else can figure out something in the meantime!

Hi. I wrote decompressors for both Omega Five and Gundam Battle Assault 2, which, like Nanoha were also developed by Natsume.

Feel free to adopt these two variations into QuickBMS.
