Sengoku Basara 2.zip 280.28 kB · 8 downloads I don't know exactly what the compression method is. but last week I made a tool to decompress it. but to compress it back is a bit difficult. The solution is to replace the compression method with a more frequently used one, like the lz family maybe, I use lz01x to compress back in my edited sb2h, it works well. SB2H_DEC.zip

It depends on what game you are editing, I edited Sengoku Basara 2 Heroes, SLPM_668.48, you need to change the decompression routines in that file (I took the LZ01X decompressor from the Havest Moon STH game), and change all the compressed files to LZ01X, if you like. If you're interested in modified this game continue this chat in PM. Edited May 6, 20242 yr by Gil_Unx

If you're interested, I can send you the application and the files I edited. Can you send it and how to change the decompression routine of SLPM_668.48? I'm really confused about this game compression issue. Thank you so much for helping me.

July 25Jul 25 Localization This looks like Capcom's YZ2 compressor. Kind of like LZ compression, but it uses Capcom's own dictionary and range coding system.I only downloaded the ISO (SLPM_66447) as I needed to figure out how the compressor worked. I have no idea if the recompressed file will actually work in the game. I will leave that for you to figure out.# Decompress python .\YZ2.py .\msg.pack .\msg.fpk # Compress python .\YZ2.py --compress .\msg.fpk .\msg.packThere also seems to be a #fpk archive in the decompressed output, but that is beyond the scope of this script. I could take a look at that, if needed. YZ2.py Edited July 25Jul 25 by Falkrian Spelling

Could I ask you to share a *.pack file from SLPM_66848 or at least some file that has the compression? I will try to get my hands on SLPM_66848 myself and see if there is any difference.UPDATE #1I have managed to get my hands on SLPM_66848 and can confirm that there was only one minor change to Capcom's YZ2 compressor. I have managed to extract msg.pack from LINKDATA.AFS and decompressed/recompressed the file with the slightly modified script. The original file and recompressed file are identical.

July 26Jul 26 Localization I have checked the files you've uploaded. Our files are pretty much identical. I also extracted the files after figuring out the FPK archive format. 👍I have completed what I set out to do here. The OP wanted to know the compression used and two years later he/she finally received the answer, heh.I have no idea what your goals are but I sincerely hope you will achieve them. Good luck!
