WipEout PSP VEX Texture Tool

Unpack and repack textures from VEX files (unofficial / fan-made)

A script for unpacking and repacking textures in VEX files as found in the PSP WipEout games (Pulse and Pure) and their respective DLCs.

This is (obviously) not an official utility, and is not related to or associated in any way with the mentioned PSP games.

Requirements

This script is written in Python 3. You need a recent version. Windows users can install from www.python.org and macOS and Linux users most likely have it already installed.

macOS and Linux: Run python3 vextextool.py --help in a Terminal
Windows: Run py vextextool.py --help in cmd.exe or Windows Terminal

Additionally, PyPNG needs to be installed. On Debian/Ubuntu the package python3-png can be installed, for others it can be installed via PIP: python3 -m pip install PyPNG (on Windows, use py instead of python3).
