The Shenmue IPAC Browser is great for repacking PKS files , but for some reason it only shows the CHARA.CHT file in PKF files (PKF files contain the PVR textures)
I want to change the textures on the Capsule Toy Machines in Sakuragaoka (Scene/01/JD00)
It contains HI_GACH and GACH (HI_GACH is the machine that loads when you are interacting with it)
If you extract the HI_GACH.PKF with WINRAR you get another file HI_GACH.PKFirs317418335.tmp
Then you can use the MT5Unpacker program to extract PVRs (It will also convert & flip PNGs)
My guess is that this original compression method is GZIP(msdos not updated since 1993)
I'm not sure its even neccessary to recompress the PKF, but I cant test that till I can get the PVRs & Chara.CHT back into a readable uncompressed PKF.tmp container .
TBH i cant be arsed faffing about spending time on this, if IPAC Browser just displayed PVRs and an Import option I wouldnt be asking, I'm kinda surprised there isnt a program that does it. If you know how let me know x
