Every PS2 emulator is programmed differently. Sometimes choosing the right emulator is the only way to fix a game. Emulators are not provided pre-installed in the PS4 OS, but instead they have to be unpacked from an official PS2 CLASSICS PKG file signed by Sony. This list includes the typical usage of those emulators.

| Resident Evil - Code: Veronica || Fixes games like '''Jackie chan Adventures, SpongeBob SquarePants: Creature From the Krust Krab, Pac-man World 3, Yu-Gi-Oh: Capsule monsters, SpongeBob's Atlantis SquarePantis''' freezing at a black/splash screen. Additionally, it fixes many games requiring '''OPL's mode 2'''. Often referred to as "RECVX" || 1.7 || '''Fatal Fury,''' '''Redfaction,''' '''AOFA.'''

| Red Faction || It is prominently used to fix VU1 sensitive games. It was used to fix '''Tony Hawk games''' suddenly crashing, as well as MTVU sensitive games such as '''Star Wars Battlefront II'''.|| 1.6 || '''Max payne'''  

| The King of Fighters 2000 || Seemingly one of the most VU-accurate emus, fixing sps in games such as '''Crash Twinsanity''', '''Crazy Frog Racer'''. It also '''prevents Koei tecmo games from suddenly freezing when battle starts. Moreover, it is likely the only emulator where '''Batman Begins''' does not crash.''' Often referred to as "KOF2000"|| 1.2 || '''Roguev1''', '''KOF98''', '''Okage'''

| Destroy All Humans! || Fixed '''Tenchu: Fatal Shadows'''' crashing. || 0.1 ||  

| War of the Monsters v1 || Subjectively the best emulator to use. Used as PS2CLASSICSGUI's default emulator, it is the best one around for accurate GS emulation, as some graphical issues on the Ratchet series and Tekken 5 can only be fixed by it. Another interesting case is GTA SA's lack of need for auto flush on it, and being natively performant. Additionally, its VU0 timing is much better than Jakv2's, making it one of the best emulators on the PS4. || 0.1 || '''Rogue v1 and v2, Arc the Lad, Star Wars Jedi Starfighter'''

| --ee-cycle-scalar  || {{Universal}} ||Slowest cycles speed: 5.00<br>Normal cycles speed: 1.000<br>Fastest cycles speed: 0.100 || {{Float}} || Can benefit core sync or performance (lowering the cycle rate may affect FMVS). The default value for most emulators is ~1.0. It is highly sensitive, as any slight change may break or fix the game. (Dividing 100 with the entered value is how to find what EE clock speed percentage % the value is setting. For example, 100/5.00 = 20%) || --ee-cycle-scalar=1.0  

| --ee-context-switch-cycles  || {{Exclusive}} || Accelerate cycles (360 => 0) <br>Decelerate cycles (361 => ∞ ) || {{4 Bytes}}||Its effects are mysterious. Possibly configures how many CPU cycles the emulator should run before switching between different tasks or threads. Does not work on Jak emulators. Default value is 360. Seems to be useful for Bee Movie, Metal Gear Solid 3, as well as others with IPU issues.|| --ee-context-switch-cycles=2700?

| --ee-hook  || {{Variable}} || AdvanceClock<br>FastForwardClock<br>Mfifodrain || 4 Byte hex (offset),string,4 Byte hex (opcode),4 Byte Decimals (advanceclock value)|| Runs the specified functionality each time a selected EE offset is reached. FastForwardClock and AdvanceClock help fix core sync issues, but can be used as a speedhack. It is believed that AdvanceClock stalls the EE for a specified amount of cycles, while FastForwardClock behaves similarly. They are commonly used on the offset directly succeeding an affected CTC2 instruction. For a mysterious reason, some offsets are ignored by AdvanceClock - it could be that this function only works on instructions 2 cycles ahead of a branch, likely specifically designed to work at both the start or end of a branch. However, this is only the case for old emulators like King Of Fighters 2000 and War Of The Monsters. Newer ones such as Jak operate differently, where AdvanceClock only works 2 cycles ahead at the end of a branch instruction.<pre>

It helps fix timing issues. It runs the specified functionality each time a selected IOP offset is reached. FastForwardClock and AdvanceClock help fix core sync issues. It is believed that AdvanceClock stalls the IOP for a specified amount of cycles, while FastForwardClock behaves similarly. For a mysterious reason, some offsets are ignored by AdvanceClock - it could be that this function only works on instructions 2 cycles ahead of a branch, likely specifically designed to work at both the start or end of a branch (on newer emus, only the end of a branch works).
