Open PS2 Loader (OPL) is a 100% Open source game and application loader for the PS2 and PS3 units.

TAR Support Overview (ART / CFG / CHT)
sOPL now supports loading artwork, per‑game config, and cheat files directly from TAR archives.This eliminates thousands of filesystem lookups and provides a massive speed boost on HDD, MMCE.
Supported TAR files
- ART/art.tar — Covers, backgrounds, icons, titles, etc.
- CFG/cfg.tar — Per‑game configuration files
- CHT/cht.tar — Cheat files (.cht)
How it works
- TARs are lazy‑loaded only when needed.
- A binary cache (*_cache.bin) is generated on first load.
- Cache is reused on every boot.
- Cache auto‑invalidates only if the TAR file size changes.
- Only one device can be used for each TAR file. (e.g. art.tar on MMCE, cht.tar on MMCE, cfg.tar on HDD)
