OPL APPS Menu: Loading PS2 Homebrew

The APPS section in OPL is where PS2 homebrew ELF files live, separate from your Games list. Here's what it's for and exactly how to add your own apps to it.

Inside OPL, the APPS menu is a dedicated section for launching PS2 homebrew — standalone .ELF programs like utilities, media players, and emulators — separate from the Games list, which is reserved for ISO-based PS2 titles.

If you've ever wondered why OPL has both a "Games" list and an "APPS" list, this is the reason: Games expects ISO/ZSO disc images, while APPS expects standalone executables (.ELF files) that don't need a disc image at all.

What Belongs in APPS?

  • Homebrew utilities — tools like OPL Util for splitting large files, or PS2RD as a standalone cheat engine.
  • Media players and browsers built for the PS2 homebrew scene.
  • Other loaders or emulators designed to run as PS2 ELF applications.

Regular PS2 game ISOs do not go in APPS — those belong in the DVD/CD folders covered in our PS2 ISO games guide.

How to Add a Homebrew App to OPL's APPS List

  1. On your USB drive, memory card, or HDD partition, create a folder named exactly APPS at the root level (same level as your DVD/CD folders, if present).
  2. Copy the homebrew program's .ELF file into that folder — and any companion files the app needs (configs, libraries), since some homebrew won't launch without them.
  3. Boot OPL and switch to the APPS tab in the menu — the app should appear automatically, using its ELF filename or embedded title if available.
  4. Select it to launch, exactly like launching a game from the Games tab.

APPS vs. FreeMCBoot's Own APPS Folder

FreeMCBoot (the memory card unlock that lets you run OPL in the first place) has its own APPS folder on the memory card, used to launch OPL itself alongside other startup homebrew. OPL's internal APPS menu is a separate, second layer — once you're inside OPL, its APPS list reads from whichever storage device (USB/HDD) OPL is currently browsing, not the memory card.

Frequently Asked Questions

APPS is a separate section inside OPL (and FreeMCBoot) dedicated to launching PS2 homebrew ELF files — utilities, emulators, and other non-game software — as opposed to the Games list, which is for ISO-based game titles.
Create a folder named APPS at the root of your USB drive, memory card, or HDD partition, and place the homebrew .ELF file (and any files it needs) inside it. OPL scans that folder and lists each ELF automatically.
Double-check the ELF sits directly inside a folder named exactly APPS at the root of the storage device OPL is browsing, and that the file isn't corrupted. Some homebrew apps also require companion files (configs, libraries) to sit alongside the ELF in the same folder.
