"Five PS1 games were recently announced for PS5 and PS4 with trophy support: Gex, Gex Enter the Gecko, Gex 3 Deep Cover Gecko, Clock Tower, and Tomba. All five games were announced to be using Limited Run Games' Carbon Engine, which so far has been primarily used to support older console emulation like the SNES and Sega Genesis, but has now officially revealed support for Sony's original PlayStation as well. These PS1 ports for PS5 and PS4 will use Limited Run Games' "Carbon Engine," which allows these classic titles to implement modern features like trophy support."

Description[edit | edit source]

The PlayStation emulator running officially on the PlayStation 4 is called internally ps1hd. Emulation on PS4 is handled differently comparing to PS3, PSP and PS Vita. Each PS1 game PS4 package file (.pkg) include emulator itself, so there is no included emulator in PS4 firmware. Fact that emulator is now included in game PKG, is slightly complicating providing compatibility list, as emulators include some per title patches, and different default settings. Next difference is that BIOS/ROM in external file is included in .pkg, emu need different region bios for different region titles. This time bios is not any special version, standard SCPH-550X is used. PS1 Emulator supports LUA scripting by "Lua Bridge", is powerful interface that provide many possibilities to improve compatibility. Memory card is created at first run of emulator, so you don't need to include one in pkg. Emulator have some leftovers from PSP emulator (like axinsnreplace), so core of non PS1 specific functions is the same as in PSP emu. Rest of emu seems to be "inspired" by mednafen.

Emulators[edit | edit source]

Every emulator is programmed in a different way. Sometimes, choosing the right emulator is the only possible way to fix a game. Emulators are not provided pre-installed on the PlayStation 4. They have to be unpacked from a container that is downloaded from the PS Store for each specific PS1 game. The following list includes the typical usage of some of the emulators.

Emulator Usage API Version Similar emulators (Usage)
Syphon Filter Most popular emulator so far and the one with the highest compatibility. It is used in PSXFPKG v0.3 as the default emulator ? ?
MediEvil An unofficial emulator made by Sony that is very bad in terms of compatibility. ? ?

PAL Libcrypt games[edit | edit source]

Some PAL PSX games include libcrypt protection, those are known to cause issues for emulators.

Known Issues[edit | edit source]

The exact effects of libcrypt depend on the game. However, they usually render the game unplayable in some form. Here is list of libcrypt-caused issues known to the community. Be sure to patch these games before creating a pkg, or try to fix them by using the --libcrypt command in the emulator configuration.

Game Behavior
Ape Escape (PAL)

Main menu navigation will be completely disabled, making you unable to start the game.

Crash Team Racing (PAL)

Game will hang at the end of the loading screen, when trying to use a warp from the main level to any race track.

Final Fantasy VIII (PAL)

Game immediately hangs on a black screen. It doesn't even play any intros.

Legacy of Kain: Soul Reaver (PAL)

The game will hang when you're introduced with the combat tutorial when the camera pans to show the enemies.

Lucky Luke: Western Fever (PAL)

The game stops when you get to the Mexican guy blocking the bridge, he just won't move from there, ever. Even when you complete the quest. The game also has anti-cracking protection where the game will block a path with a fallen tree + maybe more.

MediEvil (PAL)

Will have a disc error icon upon loading The Hilltop Mausoleum. Interesting to note this was actually the FIRST game to use LibCrypt.

MediEvil 2 (PAL)

Will also have the same disc error icon as above, except upon loading Kensington.

PGA European Tour Golf (PAL)

In the third hole of the first tournament or by selecting some holes, the game will get stuck in "demo" mode (and will not you play anything).

Resident Evil 3: Nemesis (PAL)

Will hang at the "Game contains violence and gore" screen.

Spyro 3: Year of the Dragon (PAL)

Interesting case for this one, the game will eventually randomly delete eggs, reset progress with unlocked characters, remove sheep in boss battles, change the language and even tell you off for playing a "hacked copy" + more. Interesting to note that the game also detected early LibCrypt knockout PPF patches back when the game was first released as it had checksum checks throughout the game, which caused the same effects above. The US platinum release only has anti mod detection (not libcrypt) and will do the above effects if it realises it's been modified. The original US release appears to not have any protection.

This is Football (PAL)

Hangs on the loading screen going ingame.

V-Rally: Championship Edition 2 (PAL)

The game will endlessly load on the heartbeat loading screen (with no disc activity).

Vagrant Story (PAL)

Will hang on the "now loading"-screen, after choosing "new game" on the main menu.

Wonderworld 2: Arena Of Courage (PAL)

Still hangs on the "Loading, please wait..."-screen, when you start the mission.

Wip3out (PAL)

The game will freeze when passing the finish line.

Multi-Disc support[edit | edit source]

This needs more testing but in theory it should work as follows.

On Real PS1 Hardware, PS2, PSP, PS Vita, PS3[edit | edit source]

Example Game: Final Fantasy VII containing 3 Discs:

  • Before the Game asks you to change Discs, it will ask you if you wish to save the Game.
    • If doing so, the Save File already creates a "Flag" containing Information that this Save File requires the next Disc (this is perfectly visible with Final Fantasy VIII as seen here).
      • Example: When Aerith dies and you fight JENOVA, the Game creates the Save File asking for CD 2 while you are still on CD 1.
  • After you saved the Game, it will immediately ask you to insert the next Disc.
    • The reason why this works and it's supported because in theory, you could save your Game right before you get asked to change the Disc but instead of doing so, you shut down your console and decides to play further tomorrow.
      • So when loading the same Save File on next day, it will already ask in the beginning for the next Disc.
        • If the next Disc is already inserted, then it will load the Game immediately.
        • If not then it will ask again for switching Discs (same when inserting a wrong Disc like "Disc 3" for instance but "Disc 2" is needed).

So how to do this on a PS4?[edit | edit source]

Since as mentioned above the problematic we have is that every PKG contains not only the Game as an Image-File, but also the Emulator and a Save File itself. So a workaround is needed:

  • You create a FPKG containing Disc 1 of Final Fantasy VII only (Example Content ID = CUSAFF7D1).
  • You play the Game normally until it asks you to save the Game before it will ask you to change the Disc.
  • Save the Game and close the Application.
  • On your PS4 Harddrive, there should be theoretically the Save File somewhere (within the Game Files from the Game itself ???).
  • Dump the Save File and edit the "Parameters" (PARAM.SFO ???) so CUSAFF7D1 gets into CUSAFF7D2.
  • Create your next FPKG containing Disc 2 of Final Fantasy VII only and insert your edited Save File (Content ID = CUSAFF7D2 for both the FPKG as the Save File).
  • Start the new FPKG created and it should recognize your Save File and load the Game from the beginning of Disc 2
  • Do the same process for every other additional Disc.

Alternative solution - Disc Merge[edit | edit source]

Alternatively ps1 discs can be merged into single bin/cue. There could be potential limitations in file size because MM:SS:FF can only go up to 99:99:99 which translates to around 870MB. For sure this will be problem for games with CDDA tracks. For now there is no confirmation that this limit apply to data only games. How hard is disc merging depends highly on game we want to use. Parasite Eve is one of easiest games to do that since second disc check is triggered only if files from disc 2 are not present on current disc, which they are since discs are merged. Game also use the same EXE and PE file on both discs, and do not use lba based tables. So merging discs is literally repacking them into single disc. But different games use different approaches, games like MGS need additional patches to few files to skip shell open checks, and lba adjustments. For now Chinese Parasite Eve fan translation is only confirmed game that works (thx 苏宇 for playing whole game to test it).

Memory mapping[edit | edit source]

Offset From Offset To Name Memory Name (PS4)
0x200000000 0x208000000 R3000 Memory HeapDirectMem[0]

Converting PSX cheats for the PS4[edit | edit source]

PSX cheats into a shn 

Only tested in Syphon Filter's emulator

1. Get an offset [You can get them from Gamehacking.org / Duckstation / Epsxe]

2. Remove the first 2 numbers from the offset

3. Increase the offset by 0xEB2A0 using a hex calculator and add it to your shn

For ps4cheater 

Only tested in Syphon filter's emulator

1. Get an offset    [You can get them from Gamehacking.org / Duckstation / Epsxe]

2. Remove the first 2 numbers from the offset

3. Increase the offset by 0x2000EB2A0 using a hex calculator and use it in ps4 cheater

PC register script (Syphon Filter)[edit | edit source]

TOC file layout[edit | edit source]

For multi bin images, probably requires an emulator from PS Plus.
Track entry structure:

Entry Nº Offset Length Name Example Notes
1 0x00 0x01 (1 byte) TYPE 0x41/0x01 entry flags
0x01 0x01 (1 byte) TNO 00 Track number, usually 00, bcd
0x02 0x01 (1 byte) POINT 0xA0/0xA1/0xA2/0x01/0x02/0x03/etc bcd + special case A0-A2.
0x03 0x01 (1 byte) MIN varies absolute, bcd
0x04 0x01 (1 byte) SEC varies absolute, bcd
0x05 0x01 (1 byte) FRAME varies absolute, bcd
0x06 0x01 (1 byte) ZERO 00 always zero
0x07 0x01 (1 byte) PMIN varies bcd
0x08 0x01 (1 byte) PSEC varies bcd
0x09 0x01 (1 byte) PFRAME varies bcd
Up to 102 same structure than the previous entry

POINT indicates successive track numbers, and PMIN, PSEC and PFRAME indicate the starting time of that track.
POINT = A0, PMIN gives the physical track number of the first piece of data (PSEC and PFRAME are zero).
POINT = A1, PMIN indicates the last track on the disc
POINT = A2, the starting point of the lead-out track is given in PMIN, PSEC and PFRAME.
POINT = 01 - 99 Index number within track.
POINT = 00, Pause (2sec?, Also pregap?)

Folder/File layout[edit | edit source]

Example: MediEvil internal emulator. Standalone PKG can differ.

Remove dithering[edit | edit source]

Universal dithering removal patch, works with every single game. PS1 cheats/patches are no longer required to disable dither pattern. To apply unself self file, edit, and sign it again after that. Alternatively you can use cheat engine, offset need to be adjusted to emu base then.
Replaces *and ecx, 7FFh* with *and ecx, 5FFh* to always remove dither enable bit on E1 write.

  • Emu memory offset: 0x50EA2
  • Elf memory offset: 0x54EA2

Original bytes: 

81 E1 FF 07 00 00

Replace to: 

81 E1 FF 05 00 00
