Major improvements to VPP, PEG, and ASM parsers: vpp.xscript: - Support all VPP versions (4-10) for Saints Row 1-4 and Red Faction - Add container type detection (str2, packfile, etc.) - Improved compression handling (zlib, LZO, auto-detection) - Better recursive parsing of nested archives peg.xscript: - Full PEG texture container parsing - Support for multiple texture formats (DXT1, DXT3, DXT5, etc.) - Xbox 360 and PC format variants asm.xscript: - Animation state machine container parsing New format definitions: - anim.xscript: Animation data - audio.xscript: Audio containers (bank files) - mesh.xscript: 3D mesh geometry - morph.xscript: Morph targets - rig.xscript: Skeletal rigs - sim.xscript: Simulation data - zone.xscript: Level zone data Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
