[PS2 Scene] Open PS2 Loader v1.2.0.3 Beta released

Two quick fixes for the fork of Open PS2 Loader , the homebrew application and game loader for PS2 and PS3 drives includes some interesting features not present in the official release such as support for exFAT drives and HDDs larger than 2TB.



Open PS2 Loader (or more commonly abbreviated OPL) supports three categories of devices: USB Mass Storage Devices, SMB Shares, and PlayStation 2 HDD Drives.

USB devices and SMB shares support USBExtreme formats and *.ISOwhile PS2 HDD supports HDLoader format, all devices also support ZSO (compressed ISO) format.

The application allows you to set the resolution for the game, create virtual memory cards (on USB devices or HDDs), includes compatibility with the Dual Shock 3/Dual Shock 4 controller (via USB connection) and Cheat support.


  • OPL-Launcher support.
  • HDL and NBD server support.
  • iLink support.
  • MX4SIO support.
  • Controller settings menu.
  • Gamepad macro (editing gamepads – requires PADEMU).
  • OSD language setup menu.
  • Application menu.
  • Expanded SMB ports.
  • Allows the use of partitions other than +OPL.
  • Various fixes + updates from stable version v1.1.0 + v1.2.0 Beta.

Types of release

The package containing Open PS2 Loader included several types of the same OPL version . These types are equipped with more or less the same functionality.

Type (may be a combination) Description
“Release” Regular OPL release with GSM, IGS, PADEMU, VMC, PS2RD Cheat Engine and Parental Control.
“DTL_T10000” OPL for TOOLs (PS2 DevKit).
“IGS” OPL with InGame Screenshot feature.
“PADEMU” OPL with pad emulation for DS3 and DS4.
“RTL” OPL with right-to-left language support.

How to use

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

Folder Description Mode
“CD” For games on CD media, such as blue-backed discs. USB and SMB
“DVD” For DVD5 and DVD9 images if using NTFS file system over USB or SMB; DVD9 images must be split and placed in the root of the device if using the FAT32 file system on USB or SMB. USB and SMB
“VMC” For virtual memory card images – from 8MB up to 64MB. Everyone
“cfg” To save configuration files for game. Everyone
“ART” For game art images. Everyone
“THM” For theme support. Everyone
“LNG” For translation support. Everyone
“CHT” For cheat files. Everyone
“CFG-DEV” To save configuration files per game, when used by an OPL development build, also known as a beta build. Everyone

OPL will automatically create the directory structure the first time it is run and enable the preferred device. For HDD users, a 128MB+ OPL partition will be created (you can enlarge it using uLaunchELF if needed).


Game files on USB need to be perfectly defragmented file by file or whole disc and Dual Layer DVD9 images need to be split to avoid the 4GB limitation of the FAT32 file system. We recommend using the Auslogics Disk Defrag program for best results.


You also need to make use of another program on PC to convert or split games in USB Advance/Extreme format, such as USBUtil 2.0.

SMB extension

To upload games via SMB protocol you need to share a folder (for example: PS2SMB) on the host machine or NAS device and make sure it has full read and write permissions.

USB Advance/Extreme format is optional: images *.ISOare supported using the above folder structure with the added benefit that DVD9 images do not need to be split if the SMB device uses the NTFS or EXT3/4 file system.


For PS2, internal 48-bit LBA HDDs up to 2TB are supported. They must be formatted with HDLoader or uLaunchELF (uLaunchELF is recommended). To start OPL, you can use any of the existing methods to load an executable elf file.


On PS3, you need an original SwapMagic 3.6+ or 3.8 disc (there are currently no other options). The steps to load OPL on a PS3 are:

  2. Create a folder in the root of the USB device called SWAPMAGICand copy the file SMBOOT0.ELFinto it.
  3. Launch SwapMagic on PS3 and press the  +  combo to launch Open PS2 Loader.

There are 4 forms of throwing files .elfin SwapMagic.

  • SMBOOT0.ELF + 
  • SMBOOT1.ELF + 
  • SMBOOT2.ELF + 
  • SMBOOT3.ELF + 


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


Changelog v1.2.0.3

  • Fixed issues with manual boot mode for devices.
  • Fixed problems with hang on startup.
  • Fixed issues with IGR/lock not working.
  • Fixed renaming/deleting games not updating the game list.

Changelog v1.2.0.2

  • [Fix] OPL displays error 221 no hard drive connected when no hard drive is connected.
  • [Fix] OPL damages GPT formatted hard drives. The APA driver ends up writing a bunch of data to the drive which corrupts the GPT partition table.
  • [Fix] Need to enable HDD support in addition to BDM devices. “HDD” has been added to the BDM device list in the settings menu.
  • [Fix] There is a “ghosted” HDD game menu showing nothing.
  • [Fix] Support BDM device hot plugging. BDM devices that can be removed (USB, iLink, MX4SIO) can now be “hot plugged” while in OPL and their in-game menus will appear and disappear accordingly.
  • [Fix] Unable to set UDMA mode for games on exFAT HDD.
  • [Fix] Problems with games with online support. See the list of games below for more details.

Since the previous builds I’ve released have the potential to corrupt the data on the HDD, I’d recommend doing a fresh format of the HDD if you run into problems. I removed the other two versions from my github to prevent anyone else from using them and potentially corrupting their disk .


Important: There are a number of people who have confused “sector size” with “cluster size” or “allocation unit size” while formatting their HDDs. Sector size is nothing configurable in Windows or MacOS without third party tools. When formatting the HDD in Windows/MacOS what is shown is the cluster size (labelled as “Allocation Unit Size”), this is NOT the sector size. The sector size must be 512 and cannot be configured in Windows/MacOS. The cluster size (or “Allocation unit size”) should be set to “default”.
