Editing PS1 Emulation

== Description ==

Playstation 1 emulator called internally ps1hd. Emulation on PS4 is handled differently comparing to PS3. 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 [[PS1_Classics_Emulator_Compatibility_List|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.

<br>Lua patches are split between 2 categories R3K (r3000 mips), and EM (emulator). Objects do not need to be called in order for their commands to be usable, contrary to the PS2's emulator.

== Emulators ==
<pre>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 ps4, they have to be unpacked from a backup that's downloaded from the ps store from that specific game. this list includes The typical usage of some of The emulators.</pre>

=== Known Issues === 
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 emu config.

{| cellspacing="0" cellpadding="2" border="1" class="wikitable" style="text-align: center;"
! style="width:25%" | 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.

* Libcrypt info mostly taken from: https://github.com/Kippykip/SBITools#libcrypt-failed-check-causes-and-effects

== Multi-Disc support ==
This needs more [[User talk:139.47.102.134|testing]] but in theory it should work as follows.

=== On Real PS1 Hardware, PS2, PSP, PSV, PS3 ===
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 [https://i.ytimg.com/vi/xDSRMghD6Is/maxresdefault.jpg 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? ===
Since as mentioned [[PS1 Emulation#Description|above]] the problematic we have is that every PKG contains not only the Game as an Image-File, but also the [[PS1 Emulation|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]] = CUSAFF7'''D1''').
* 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 ''CUSAFF7'''D1''''' gets into ''CUSAFF7'''D2'''''.
* Create your next FPKG containing '''Disc 2''' of Final Fantasy VII '''only''' and insert your edited Save File (Content ID = CUSAFF7'''D2''' 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.

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