Klonoa 2 Texture hacks?

[ArcadeNblog]

I'm currently trying to rip textures from Klonoa 2: lunatea's veil for the PS2. I was able to find a program that decompiles the ISO. Inside, there are a bunch of .IRX files and disc images 7-zip can't open (.IMGs)

Could I please have some info on how to do texture hacks for the game properly? (If someone else could relay information on music and text edits, that would also be appreciated.)
