Has anyone managed to figure out klonoa 2's files?

[Shinigami_Guntz]

after nearly a month of digging into the files i can't seem to get into the iso without some sort of trouble, would it better if i just tried to rip of the files from a physical copy of the game or just try to understand the insanely garbled up text in the kldata.bin file? Also, if i try to open it in winrar it tells me the bin file is either unsupported or damaged, it literally wont open in any program i use and its getting on my nerves....i honestly feel like its going to be some super obvious format or something, maybe looking through the files of other games namco released around the same time and seeing if they have similar layouts may help. Like tekken 4 maybe?
