This page collects information on the PSX - not the PlayStation (1), but the Japan-only PS2 variant with advanced multimedia and DVR-functions. Being a hybrid of a DVR and a game console, it has a lot of unique traits. Sadly, it has a lot of reliability issues, most notably nowadays dying Hard Drives and Disc Drives. This article aims to make repair easier and collect information that might help in circumventing the HDD vendor-lock in the future. It also aims to be a general collection of information on reverse-engineering of the PSX.

Models[edit | edit source]

The PSX was released in eight retail configurations during its lifespan (nine, if you count the silver DESR-5100S); the 5000 series (with a solid white case and an embossed logo on top) shipped with 160 GB Hard disk drives, while the 7000 series (with a more premium acrylic outer case, a colored logo on top and black stripe with blue LED strip at the back) contained 250 GB drives. Software updates were made available by disc and download.

All models have two sets of status LEDs and Infrared receivers; one along the front for horizontal orientation, and a second strip along the top-back for vertical orientation. The 'DISC REC' indicator is only on the front of the device in models DESR-5500/DESR-7500/DESR-5700/DESR-7700.

Package management[edit | edit source]

PSX firmware has some kind of package management. There are two package managers: "Packman" and "PackmanJr". Packages can be either "flash_package" (installed to onboard flash) or "non_flash_package" (installed to HDD). Additionally, the package manager can update the firmware of the disc drive and DVRP from firmware images contained in packages.

Onboard flash[edit | edit source]

The PSX has a flash memory on board called xfrom, containing the xosdmain.elf XMB-executable and some other files. xosdmain.elf is always located at xfrom:/BIEXEC-SYSTEM/xosdmain.elf. The other files differ between PSX1 (DESR-x000 and DESR-x100) and PSX2 (DESR-x500 and DESR-x700). Their main purpose is setting a boot mode for xosdmain.elf. On PSX1, several .opt files can get temporarily created (or deleted) to configure the boot mode. On PSX2, this is handled by a single file named bootflag.txt.

File types[edit | edit source]

This list is incomplete.

  • OPT: .opt files are behavior switch tokens used on PSX1 (DESR-x000 and DESR-x100). They were first used on the HDD-OSD (Browser update bundled with HDD utility disc to browse HDD). The XFROM bootloader is capable of using such files to perform certain tasks in case the XMB becomes unresponsive or doesn't boot. The contents are not important, however, Sony seemed to make them 512bytes filled with 0xff. They're expected at the program CWD (xfrom:/BIEXEC-SYSTEM for this case)

The following file tokens have been confirmed:

Caption text
File Purpose
repartition.opt repartitions the DVR area? gets created when requesting repartitioning
make_game_area.opt Resizes PS2 HDD area to 40 GB? (Needs repartition.opt, gets created when requesting repartitioning to increase PS2 area size)
delete_game_area.opt Resizes PS2 HDD area to 2048 MiB? (Needs repartition.opt, gets created when requesting repartitioning to decrease PS2 area size)
contents.opt unknown, gets created when requesting repartitioning
  • PAK: encrypted archive format that stores update data. Can be found on the PSX Update Disc. Has been reverse engineered and decryption/unpacking is possible.
  • REL: executable binaries.
    • For PSX1 and PSX2, all REL files are encrypted with the following: Has been reverse engineered and decryption/unpacking is possible.
    • For PSX1 and PSX2, REL files other than main.rel are SN Systems dynamic libraries in a unique format not compatible with libsn released with ProDG.
    • For ApplicastEmulator, REL files are in PE format.
    • For KDL (2007 and newer), RDZ, BDZ (2005 and newer), BDP/BDV (2008 and newer, excluding 2010 models), and SMP (except SMP-N100), REL files are in ELF dynamic library format in either MIPS or ARM32 depending on the system.
    • Unpacking using this program requires a keyblob (see PSX_rel.cpp), that can be obtained from a decrypted and unpacked xosdmain.elf:
      • Obtain xosdmain.elf (either from HDD, from flash or from an update disc)
      • Decrypt xosdmain.elf using kelftool with these Keys
      • Unpack the decrypted xosdmain.elf using this program
      • Find the 305 bytes of the keyblob. The keyblob contains the bytes 0x9100000001 after the first 32 bytes. This should make it easy to locate using a hex editor. The correctly extracted keyblob has a SHA-1 of d3c6954bb6c8c122ba547f4294c90ba739e5bfa8df37a293f532bab16a404e45.
      • Copy the keyblob as a C-array using your hex editor and insert it into the PSX_rel.cpp, compile and run (./PSX_rel <input> <output>).
  • STAR: archive format used to store packages inside the INSTALL3.PAK on the 2.11 update disc (earlier update discs simply stored packages as folders). Neither compressed nor encrypted. Has been reverse engineered and unpacking is possible.
  • IRX: Binaries that run on IOP and can be dynamically linked to an executable. Stands for IOP Relocatable eXecutable. Not specific to the PSX, but also used in normal PS2 software. For package-installed files, it is encrypted in same format as REL files.
  • ioprp280.img/ioprp300x.img: Base image for IOP reboot. Not specific to the PSX, but also used in normal PS2 software. For package-installed files, it is encrypted in same format as REL files.
  • AMX: Small/Pawn compiled unencrypted files.
  • BNX: Small/Pawn compiled DNAS encrypted files for PSBB.
  • BD/HD/SQ: CSL related BGM file.
  • jis2ucs.bin/ucs2jis.bin: Encoding conversion table.
  • BMP/GIF/JPG/PNG/TGA: Image file.
  • CER: SSL certificate.
  • gmm.db/registry.db: Database in sqlite2 format for PSX1 or xDb format for PSX2 and newer.
  • djboxmini.elf/dvdplayer.elf: KELF files.
  • serverlist.enc/hostname_keypair.enc: encrypted listing for PSML1 viewer.
  • icon.sys/ICO: PS2 savefile icon related files.
  • RAW: raw/headerless image file.
  • SUB: part of template for DVD menu.
  • TM2: TIM2 image file.
  • TXT: text file.
  • UDM: DVRP firmware updates.
  • XML: text XML file. For systems after PSX2 (e.g. libx2) they are binary instead.
  • XSB: part of xAudio.
  • atafirm.bin/profile.bin: part of DVD firmware update.
  • VR_MOVIE.VRO.ONCE: part of DVD-VR template.
  • noboot.cnf: template of system.cnf for partition creation of xDJB for not booting.
  • DIC: translation text file only in PSX2 and newer.
  • ripping.tur/OCM: files for OpenMG.

Special files[edit | edit source]

  • xosdmain.elf is the main XMB executable and stored on flash/xfrom at xfrom:/BIEXEC-SYSTEM/. Another two copies of it are stored on the HDD (once at hdd0:/__system/BIEXEC-SYSTEM/ and another in the boot package's folder at hdd0:/__system/xosd/packages/).

Packed in a similar way as the PS2's OSDSYS, it is an encrypted KELF that must first be decrypted e.g. using kelftool (use these Keys) and then decompressed using this program.

Hard Drive[edit | edit source]

See also: Hard Drive
Unlike the PS2's official hard drives, the PSX's hard drives are not externally rebranded. They do however implement the same proprietary firmware features as the official PS2 hard drives do. A hard drive with these features is required for the console to boot. Thus, the PSX's hard drive can currently only be replaced with another PSX's hard drive or one of the official PS2 hard drives. See: Sony custom ATA commands

 Using an official PS2 hard drive requires additional work due to their different sizes and partitioning/sectioning schemes. This also makes the DVR functions only barely functional due to the lack of space for a properly sized DVR area on the disk.
Note: System software 2.x (used by DESR-x500 and DESR-x700) requires the DVR-partition to boot!

All PSX hard drives are 3.5 inch IDE/P-ATA drives with a capacity of either 160 GB or 250 GB, depending on the console model.

OEM drives used[edit | edit source]

This list might be incomplete; please add yours if it's not in the list.
While some of these drives support UDMA 6 (ATA/133), PSX itself is limited to UDMA 5 (ATA/100).

Disc Drive[edit | edit source]

The PS2-part of the drive is based on the H/I chassis SCPH-500xx/5500x fat PS2 drive, both electrically and mechanically. The whole drive assembly is connected to the motherboard using 3 flat flex cables: One is an IDE connection to the dedicated drive board of the PSX-part, one provides power (5V, 12V, GND) and also connects the PS2-part sled motor to the motherboard (since it is controlled by the motherboard directly), and one connects the KHS-400C PS2-part pickup to the motherboard, since it is also directly controlled by the motherboard. The spindle motor is always controlled by the dedicated PSX-part drive electronics over IDE, even in PS2 mode.

Two different models have been made; the older one is used in DESR-x000 and x100, the newer one in DESR-x500 and x700. The drive has an updatable firmware for the PSX-mode part of the drive; at least the newer drive actually received such an update (Sony model name: DW-DX02A, known firmware versions: 0YX7 Sep 15 2004, BV1M Mar 08 2005).

Notes[edit | edit source]

  • Contrary to some information on the internet, the drive does NOT seem to be married to the individual console. It is however likely that you can not replace the older drive type by the newer type or vice versa (needs verification, please contribute), due to different specifications and features, despite identical electrical interfaces (which is just IDE/ATA through a 50 pin flat flex cable).
  • Several variants of the Sanyo SF-DB11 pickup exist, with only some of them being compatible with the PSX. Trying to install an incompatible one will (sometimes? always?) burn the flat flex cable and/or blow the 5V drive-power fuse on the motherboard depending on your luck (known compatible variants: bottom sticker number starts with DB11B; known incompatible revisions: bottom sticker number starts with DB11N, 11NX or 11NXL). It didn't seem to damage anything else though; most notably all electronics (after replacing the blown fuse) AND the laser pickup (after being installed into a compatible PC drive that uses this variant) survived.
    • These different types are seemingly actually called "SF-DB11B" (the one compatible with the PSX), "SF-DB11NS", "SF-DB11NX" and "SF-DB11NXL" (all three incompatible with PSX). These are best differentiated by the bottom sticker, not by the embossed revision number on the top.
    • Symptoms of a blown 5V fuse:
      • Drive appears dead (the slot-mechanism however still works and correctly pulls in and ejects discs)
      • When forcing the console into PS2 mode through FMCB, inserting a disc will cause the PS2-laser to start focussing since it runs from another power source, however, the spindle motor will not spin
      • The front USB port does not work
    • Comparison of an compatible type (left) with an incompatible type (right) of SF-DB11 with the bottom shielding removed. Note the missing potentiometers for setting the oscillator frequencies on the incompatible type, where fixed 680 Ohm resistors are used instead:
  • There is an official documentation of the KWS-200A used in the DESR-x000 and DESR-x100 PSX, released by Sony itself, however, both power monitoring PDICs are absent in the drawing:
