![]() ![]() All functions for 2A, 2B, 2C, 2D must be redirected to ports on multi-tap 1 by using memory patches. In some cases, the emulator can be flawed in how it handles multi-tap when it involves "-mtap2". To achieve that, we need to disable the first mtap. Some games require multitap to be selected only on second port (1, 2-a, 2-b, 2-c layout). The values are correct but the multitap only works in certain games. || -cdvd-sector-seek-cycles=1Īudio latency must be between 0.010 and 4.0 Set the speed at which the emulated CDVD spins. ![]() Some games require moderate speed, too slow or too fast could cause audio problems. Kinetica uses 40000, Psychonauts 4000, Red dead revolver 5000, Rise of kasai 31000. Higher values are slower, lower values are faster. Sadly this command isn't supported by many emulators, but jakv2 is confirmed to support it || -switch-disc-reset=1 Useful for games like Samurai warriors 2 that include an Import data feature. None, gpu, edgesmooth, motionvec, point, motionvector, smooth, motionġ = Enables resetting the game upon disc swapĠ = Disables resetting the game upon disc swap|| 0 Can be used to prevent resetting the game when switching multiple discs. Might seem like a useless command, but a tiny number of games refuse to boot without a selected language. Slowest,slower,slow,normal,fast,fastest,turbo Path to folder with XXXX-YYYYY_a fileĭebug option that requires an unleaked debug ps2 bios The rest of the CLI and LUA commands can all be found inside of any emulator's Eboot.bin file.Ĭonfig-emu-ps4.txt commands CommandĬreates a log file with information that is rarely useful Patching EE/IOP memory, Conditional hooks. XXXX-YYYYY_a - Used for per disc advanced scripts.GS, VU, EE, IOP, FPU, COP2 emulation settings, are here. XXXX-YYYYY_cli.conf - Stores per disc advanced settings.pkg with all commands originally used in cli.conf file. But unofficially can be also used for advanced settings for global effect in multi disc. config-emu-ps4.txt - Stores paths, basic video/audio settings in official packages.Emulator Configuration Files Įmulator configuration is handled by 4 files: The emulator uses openCL for GS, and likely other components as well. This is resolved by clamping, accurate math used per memory offset, and/or converting floats to double precision. Compared to the PS3 CPU, x86-64 is doing a worse job in mimicking FPU and VU floats calculation behavior. This is first time that Sony has ever cared about floats in their emulators. The PS2 Emulator supports LUA scripting by "Lua Bridge", and it is an extremely powerful interface that provide many possibilities to improve compatibility. Memory card is also decrypted, but the emulator checks the CRC of some of the regions to ensure that the memory card was Not modified. But the emulator still supports LIMG sector that allows the usage of non-2048 sector size discs. Another important thing is the lack of encryption mechanism for PS2 game disc image file, this time it is just a plain ISO file. The BIOS itself is included in the game's pkg and it is the exact same BIOS that was used in the ps2_netemu. For game crashes we use RECVX, and for VU accuracy we use roguev1. Since emulators include per title patches, and different default settings, and since the Playstation 2 hardware is a complex system to emulate, any small change in configuration can make or break a game.Ĭurrently the most commonly used emulator is Jakv2 because it is the most compatible. And that alone is a challenge for accurate emulation. Like the functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, or sceSystemServiceShowImposeMenuForPs2Emu.Įmulators are programmed to be accurate for the games that they were made for. The ps4 does not have a native built-in emulator in its firmware, but it does have some PS2 emulator specific features. The PS4 is too weak for emulation, therefore Sony had to sacrifice accuracy for performance.Įach PS2ONPS4 package file (.pkg) includes the emulator itself. Some issues that the PlayStation 3 encountered have moved on to the PlayStation 4, along with a few new ones. 7.3 Game_ID/DiscID in PS20220WD20050620.crackĭescription PlayStation 2 emulation on the PlayStation 4 is handled with little difference to the PlayStation 3.2.2.4.1.5 Does not require Object calling or Uknown. ![]()
