Complete Guide: PS2 File System (ART, VMC, CFG) for OPL with Matrix Modchip Target Audience: PS2 users with a Matrix Infinity (or clone) modchip, using OPL via SMB, USB, or Internal HDD. Goal: Structure your +OPL partition (on HDD) or root folders (on USB/SMB) correctly, verify integrity, and ensure Matrix boot compatibility.
1. Understanding the Required File System Structure OPL (version 0.9.3 to 1.2.0+) expects a specific folder hierarchy to store game art, Virtual Memory Cards (VMC), configuration files, and themes. For HDD (internal) , OPL uses a hidden partition named +OPL . For USB / SMB , it uses folders on the root of the device. Standard OPL Directory Tree OPL_Root/ (USB root or SMB shared folder) │ ├── ART/ (Game covers, art, backgrounds) │ ├── art/ (Front covers - usually JPG/PNG) │ ├── bg/ (Backgrounds per game) │ ├── icon.png │ └── dvd.png │ ├── CFG/ (Individual game settings .cfg files) │ └── SLUS_123.45.cfg │ ├── VMC/ (Virtual Memory Card files) │ └── SLUS_123.45.bin / .ps2 │ ├── THM/ (Themes for OPL interface) │ └── <theme_name>/ (folder with theme files) │ ├── APP/ (Homebrew ELF launchers) ├── DVD/ (DVD game ISOs - legacy, not needed if using HDD) ├── CD/ (CD game ISOs - legacy) ├── POPS/ (PS1 games via POPStarter) ├── LNG/ (Language packs) ├── CHEAT/ (Cheat files) │ ├── conf_opl.cfg (Master OPL config file) ├── conf_apps.cfg (App launcher config) ├── lastplayed.cfg └── opl_theme.cfg
