Open PS2 Loader

Open PS2 Loader bundle included several types of the same OPL version. These types come with more or fewer features included. | Type (can be a combination) | Description | | --------------------------- | --------------------------------------------------------------------------------------- | | `Release` | Regular OPL release with GSM, IGS, PADEMU, VMC, PS2RD Cheat Engine & Parental Controls. | | `DTL_T10000` | OPL for TOOLs (DevKit PS2) | | `IGS` | OPL with InGame Screenshot feature. | | `PADEMU` | OPL with Pad Emulation for DS3 & DS4. | | `RTL` | OPL with the right to left language support. |

OPL uses the following directory tree structure across HDD, SMB, and USB modes: | Folder | Description | Modes | | ------ | ---------------------------------------------------- | ----------- | | `CD` | for games on CD media - i.e. blue-bottom discs | USB and SMB | | `DVD` | for DVD5 and DVD9 images if using the NTFS file system on USB or SMB; DVD9 images must be split and placed into the device root if using the FAT32 file system on USB or SMB | USB and SMB | | `VMC` | for Virtual Memory Card images - from 8MB up to 64MB | all | | `CFG` | for saving per-game configuration files | all | | `ART` | for game art images | all | | `THM` | for themes support | all | | `LNG` | for translation support | all | | `CHT` | for cheats files | all | OPL will automatically create the above directory structure the first time you launch it and enable your favorite device. For HDD users, OPL will read `hdd0:__common/OPL/conf_hdd.cfg` for the config entry "hdd_partition" to use as your OPL partition. If not found a config file, a 128Mb `+OPL` partition will be created. You can edit the config if you wish to use/create a different partition. All partitions created by OPL will be 128Mb (it is not recommended to enlarge partitions as it will break LBAs, instead remove and recreate manually with uLaunchELF at a larger size if needed).

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 do not recommend using any programs. The best way for defragmenting - copy all files to pc, format USB, copy all files back. Repeat it once you faced defragmenting problem again. 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 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. HDD should be formatted with the APA partition scheme. OPL will create the `+OPL` partition on the HDD. To avoid this, you can create a text file at the location `hdd0:__common:pfs:OPL/conf_hdd.txt` that contains the preferred partition name (for example `__common`).

OPL now uses an [NBD](https://en.wikipedia.org/wiki/Network_block_device) server to share the internal hard drive, instead of HDL server. NBD is [formally documented](https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md) and developed as a collaborative open standard. The current implementation of the server is based on [lwNBD](https://github.com/bignaux/lwNBD), go there to contribute on the NBD code itself. The main advantage of using NBD is that the client will expose the drive to your operating system in a similar way as a directly attached drive. This means that any utility that worked with the drive when it was directly attached should work the same way with NBD. OPL currently only supports exporting (sharing out) the PS2's drive. You can use `hdl-dump`, `pfs-shell`, or even directly edit the disk in a hex editor. For example, to use `hdl_dump` to install a game to the HDD: * Connect with your choosen client (OS specific) * Run `hdl_dump inject_dvd ps2/nbd "Test Game" ./TEST.ISO` * Disconnect the client. To use the NBD server in OPL: * Grab the latest beta version (OPL 1.1.0 (current stable) has some bugs in the NBD server) - go to the [Releases](https://github.com/ps2homebrew/Open-PS2-Loader/releases) section and grab the one at the top. * Ensure OPL is configured with an IP address (either static or DHCP). * Open the menu and select "Start NBD server". Once it's ready, it should update the screen to say "NBD Server running..." * Now you can connect with any of the following NBD clients. ### nbd-client Supported: Linux, [Windows with WSL and custom kernel](https://github.com/microsoft/WSL/issues/5968) nbd-client requires nbd kernel support. If it isn't loaded, `sudo modprobe nbd` will do. list available export: ```sh nbd-client -l 192.168.1.45 ``` connect: ```sh nbd-client 192.168.1.45 /dev/nbd1 ``` disconnect: ```sh nbd-client -d /dev/nbd1 ``` You'll generally need sudo to run this commands in root or add your user to the right group usually "disk". ### nbdfuse Supported: Linux, Windows with WSL2 list available export: ```sh nbdinfo --list nbd://192.168.1.45 ``` connect: ```sh mkdir ps2 nbdfuse ps2/ nbd://192.168.1.45 & ``` disconnect: ```sh umount ps2 ``` ### wnbd Supported: Windows [WNBD client](https://cloudbase.it/ceph-for-windows/). Install, reboot, open elevated (with Administrator rights) [PowerShell](https://docs.microsoft.com/en-us/powershell/scripting/windows-powershell/starting-windows-powershell?view=powershell-7.1#how-to-start-windows-powershell-on-earlier-versions-of-windows) connect: ```sh wnbd-client.exe map hdd0 192.168.1.22 ``` disconnect: ```sh wnbd-client.exe unmap hdd0 ``` ### Mac OS Not supported.

As of version 1.2.0, compressed ISO files in ZSO format is supported by OPL. To handle ZSO files, a python script (ziso.py) is included in the pc folder of this repository. It requires Python 3 and the LZ4 library: ```sh pip install lz4 ``` To compress an ISO file to ZSO: ```sh python ziso.py -c 2 "input.iso" "output.zso" ``` To decompress a ZSO back to the original ISO: ```sh python ziso.py -c 0 "input.zso" "output.iso" ``` You can copy ZSO files to the same folder as your ISOs and they will be detected by OPL. To install onto internal HDD, you can use the latest version of HDL-Dump.

Currently, supported only [PS3 Backward Compatible](https://www.psdevwiki.com/ps3/PS2_Compatibility#PS2-Compatibility) (BC) versions. So only [COK-001](https://www.psdevwiki.com/ps3/COK-00x#COK-001) and [COK-002/COK-002W](https://www.psdevwiki.com/ps3/COK-00x#COK-002) boards are supported. USB, SMB, HDD modes are supported. To run OPL, you need an entry point for running PS2 titles. You can use everything (Swapmagic PS2, for example), but custom firmware with the latest Cobra is preferred. Note: only CFW supports HDD mode.

Open PS2 Loader needs the [**latest PS2SDK**](https://github.com/ps2dev/ps2sdk)

Since 05/07/2021 every OPL build dispatched to the release section of this repository will be uploaded to a [mega account](https://mega.nz/folder/Ndwi1bAK#oLWNhH_g-h0p4BoT4c556A). You can access the archive by clicking the mega badge on top of this readme

### OPL Freezes on logo or grey screen Sometimes OPL freezes when loading config files made by older OPL builds. > hold __`START`__ while OPL initializes to make it skip the config loading, then, you can save your own settings. > fixing the issue. ### Game freezes on white screen > Main game executable could not be found. Either game is fragmented or image is corrupted
