Open PS2 Loader (OPL) is a 100% Open source game and application loader for the PS2 and PS3 units. It supports three categories of devices : USB mass storage devices, SMB shares and the PlayStation 2 HDD unit. USB devices and SMB shares support USBExtreme and *.ISO formats while PS2 HDD supports HDLoader format. It's now the most compatible homebrew loader.

OPL is also developed continuously - anyone can contribute improvements to the project due to its open source nature.

Open PS2 Loader bundle included several types of the same OPL version. These types come with more or less features included.

OPL uses the following directory tree structure across HDD, SMB, and USB modes:

OPL will automatically create the above directory structure the first time you launch it and enable your favourite device. For HDD users, a 128Mb +OPL partition will be created (you can enlarge it using uLaunchELF if you need to).

Game files on USB must be perfectly defragmented either file by file or by whole drive, and Dual Layer DVD9 images must be split to avoid the 4GB limitations of the FAT32 file system. We recommend Auslogics Disk Defrag for best defragging results.

You also need a PC program to convert or split games into USB Advance/Extreme format, such as USBUtil 2.0.

For loading games by SMB protocol you need to share a folder (ex: PS2SMB) on the host machine or NAS device and make sure that it has full read and write permissions. USB Advance/Extreme format is optional - *.ISO images are supported using the folder structure above with the added bonus that DVD9 images don't have to be split if your SMB device uses the NTFS or EXT3/4 file system.

For PS2, 48-bit LBA internal HDDs up to 2TB are supported. They have to be formatted with either HDLoader or uLaunchELF (uLaunchELF is recommended).

To launch OPL, you can use any of the existing methods for loading an executable elf.

On PS3, you need an original SwapMagic 3.6+ or 3.8 disc (at the moment there aren't any other options). The steps for loading OPL on a PS3 are:

1. Rename OPNPS2LD.ELF to SMBOOT0.ELF
2. Make a folder in root of USB device called SWAPMAGIC and copy SMBOOT0.ELF to it.
3. Launch SwapMagic in PS3 and press UP+L1 then Open PS2 Loader should start.

There are 4 forms for launching elfs in SwapMagic.

SMBOOT0.ELF = UP + L1
SMBOOT1.ELF = UP + L2
SMBOOT2.ELF = UP + R1
SMBOOT3.ELF = UP + R2

Note: on PS3, only USB and SMB modes are supported.

Open PS2 Loader needs the latest PS2SDK:
