[FF4 PC/Steam] - Is there a resource unpacker and repacker available?

(1/5) > >>

Fraggoso:
I also asked in the modding subforum for FFIV:

Is there a tool that can unpack the resource file and repack them back?
I want to mess with my graphics pipeline to get rid of the big pixel/3DS look of the textures.

I couldn't find anything so far. :/

Maki:
Are you sure we are talking about the same game?
Mine Final Fantasy IV for Steam has ALL the files unpacked to bare formats
There's nothing to unpack and repack



Sound/.*AKB files are normal OGG, just play at 0x204
*.NCGR - are normal .PNG files

EFFECT.dat, STAGEMNG_f00.dat and event2d_pack.dat are indeed casual containers, but everything else has .lz extension. I bet it's LZS


EDIT:
Okay, .DAT reversed:


Main:


OffsetSizeDescription0char[4]MAGIC- "SSAM"4uintEntries count8 + (EntryID*40)40 bytesEntry8 + (EntriesCount*40)VariesFILE_data
Entry:

OffsetSizeDescription0uintFile Pointer + (EntryCount*40+8)4uintFile size8char[32]File name

About LZ:

-Not LZSS algorithm [Tested/ creates rubbish]
-Not LZMA algorithm [Tested/ unknown compression error]
-Not Zlib [Tested/ unknown compression error]

For sure some LZ compression, LZ77?

Okay, I unpacked it succesfully using LZ77 algorithm grabbed from here: https://gist.github.com/Prof9/872e67a08e17081ca00e

Fraggoso:
Sorry I didn't bought the game yet but I thought it had a container file!
Sorry for the hassle I will take a look into the png files of sort. :)

Lein:
I played this some time back, it would be nice to see a mod that improves upon the chibi models. The chibi look is really off putting as are the animations. Is it possible to export/import models and animations?

Fraggoso:
I looked at the ncgr files and it seems there's only map files stored as normal png.
I also found the tutorial pictures and basically everything that's written with graphics but I can't find any character textures.

Do you know where the character textures are stored?
Are they stored in the dat file you mentioned above?

@Lein without a tool that's not possible at all at this time.
