=== PS1 games available on PS4 PS Store ===
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.

No PS1 Classic game is available on PS4 Bluray Disc, maybe because producers like Limited Run Games thought it would be a waste to store less than 1 GB on a 25 GB Bluray Disc.

** The first game in the series was Clock Tower (1995) - first released on the SNES, later ported to PS1, PC and WonderSwan, but only ever released in Japan.
** The PS1 game is the second game, and was called Clock Tower 2 in Japan but just Clock Tower everywhere else, even though it is a sequel and not a port of the original.
** Clock Tower 2 on the PS1 is the third game.
** Clock Tower 3 on the PS2 is the fourth game.

"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."

Resident Evil Director's Cut is NOT redeemable. The rule of thumb is: if you can buy it on PS4/PS5 - and not only claim it through plus premium/deluxe sub, like Resident Evil 1 - they are redeemable from a previous purchase on PS3/PSP/PS Vita."

==== getR3KObject() ====
 
For usage examples lets declare getR3KObject() as r3k [ local r3k = getR3KObject() ] to make things closer to official configs.
<br>'''scripts/XXXXYYYYY.LUA'''
<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 ==
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.


==== getTrophyObject() ====
For usage examples lets declare getTrophyObject() as trp [ local trp = getYtophyObject() ] to make things closer to official configs.

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.
All that can be patched before creating pkg, or fixed by using --libcrypt command in emu config.

=== Alternative solution - Disc Merge ===
== Links ==
 
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).
