6.2 PS2 Memory and Hardware Mapped Registers Layout 5 Virtual PS2 (emulated machine) usage and features 4 General observations regarding PS2 Classics emulator (ps2_netemu) As desktop version for Windows, Linux and Mac of this nature software exists for over a decade already, we decided to build one which supports mobile devices too.We support operating systems that not even Microsoft and Apple themselves support anymore, such as macOS X on PowerPC Macs, and RetroArch being available on Windows OSes as far back as Windows 95.Beaucoup de chds mame sur gametronik, sans leurs roms.CECH-A/B models use ps2_emu.self able to use built-in PS2 hardware (EE/GS/Rambus memory), and have best compatibility. 13.3.2 Inside ps2_gxemu.self/ps2_softemu.selfEmulation of Playstation 2 is currently handled by 3 kind of emulators. 13.2.2 Official GXEMU/SOFTEMU extracted 12.4 Getting compatibility hardware info 11.2 TitleID/DiscID in game_ext_plugin.sprx This mean that LV2, or more friendly Game OS is unloaded before emulator is loaded. Emulators are not truly PS3 Game OS elf executables, but Guest OS'es running on LV1 of PS3. Only emulator not able to run physical discs is ps2_netemu.Emulators are self files, but not typical one. It was called ps2_softemu, and had support for original PS2 CDVD. Earlier before Sony provided ps2 classics on PS Store there was another soft only emulator strongly based on ps2_gxemu. All other models emulate PS2 thru fully software based ps2_netemu used for ps2 classics, and hacked now to use decrypted ISO files.This is set on emulator init by HV call 97 with param 1. Ps2_emu BIOS is able to run only on ps2emu version of emulator due to RDRAM check.PS3 models without Emotion Engine unit use "SPE-compatible SIMD graphics-rounding mode for VMX/Altivec Instructions" for FPU, and VU0 emulated floats calculations. Bios between ps2_emu, and ps2_gxemu/ps2_netemu are different. This is done because some games print debug info on screen when found that are run on dev bios. Also LV1 syscalls are limited to call from all emulators, but can be fully unlocked.All emulators use built-in stripped developement version of PS2 BIOS with disabled debug functions that can affect some games.
![]() Emulator Pour Software Exists ForThis is due to some PS2 math algo specific inaccuracies in FPU/VU implementation that are not present on any other hardware. Good example here are TriAce games, or Castlevania COD where SPE calculation is wrong by 1 bit making games unplayable without patch. Although SPE, and PPE SPE compatibility mode can still be inaccurate comparing to PS2. So literally what PS2 VU was originally. SPE compatible mode for PPE mean that rounding mode is set as round to zero, denormals are treated as zero, and there are no infinities or NaNs. The module used to manage memory cards is: vmc_savedata_plugin.sprx - Using a regular memory card that has been renamed result in a "The save data is corrupt (8XXXXXXX) error" Virtual memory cards are per title based, but apparently run through the current memory card system.
