MBROWS - Only used by the old OSDSYS program from ROM v1.00 and v1.01. Provides the lowest level of IOP module loading functions.
LOADCORE - The core of IOP module loading. LIBFI - This is not present in the boot ROM of the SCPH-10000 and SCPH-15000. KROM - Kanji ROM? Not sure where this is used. If no UDNL module is specified, the IOP will only have a single IOP reset in the reboot process, with the modules listed in IOPBTCONF. IOPBTCONF - Boot configuration file for the IOP, during the final phase of the IOP reset. IOPBTCON2 - Boot configuration file for the IOP, for the first phase of the IOP reset (before UDNL is loaded).
ILSOCK - i.Link socket driver - present in only the arcade ROMs.
ILINK - i.Link driver - present in only the arcade ROMs. IOP boot type, EBOOTP, IBOOTP, switch positions for DSW602 and the type of DSW602 board installed). IGREETING - Displays boot information (i.e. ICOIMAGE - Contains icons for the OSDSYS of the SCPH-18000 and newer. HDDOSD - Not sure what this does, but it is present in the expansion-bay ROMs.
HDDLOAD - Update loader for the HDD unit (and later includes the flash device). Connecting an old FILEIO EE RPC client to a newer server will result in a severe IOP crash.įNTIMAGE - Contains fonts for the OSDSYS of the SCPH-18000 and newer.įONTM - The FONT Module, used by the OSDSYS. Sony has greatly changed the semantics and design of FILEIO after some point. 0x00100000.ĮROMDRV - Encrypted ROM DRIver for the expansion-bay PlayStation 2 sets.ĮROMDRVA - Encrypted ROM DRIver for the SCPH-70000 (ROM v2.00) and later PlayStation 2 sets.ĮXTINFO - Contains the "EXTINFO" for all files in the ROM image.įILEIO - RPC server for IOMAN. EESYNC from DNAS images are evil they also perform a memory wipe of the region from 0x00084000 to. In slimlines, EECONF will also load the MAC address.ĮELOAD - The EE ELF loader, which is loaded by LoadExecPS2() to 0x00082000 for loading ELFs.ĮELOADCNF - Contains the IOP boot configuration file for EELOAD.ĮENULL - The idle thread (id #0) module, loaded to 0x00081FC0.ĮESYNC - For synchronizing with the EE, at the end of IOP resets. Also configures and resets some peripherals, depending on the model version. SCPH-70000 (ROM v2.00) and later had universal DVD ROMs, hence the existence of DVDVER* files for each region.ĮECONF - Loads part of the system configuration from the MECHACON EEPROM. SCPH-70000 (ROM v2.00) and later had universal DVD ROMs, hence the existence of DVDPL* files for each region.ĭVDVER - DVD player version number. SCPH-70000 (ROM v2.00) and later had universal DVD ROMs, hence the existence of DVDID* files for each region.ĭVDPLA - DVD player executable for slimlines.
PIF) is up.ĭECKARD - The SCPH-7500x has a newer PowerPC processor in place of the IOP, and requires code to emulate the IOP.ĭVDCNF - Contains IOP boot configuration file for the DVD player.ĭVDELF - DVD player executable for expansion-bay consoles.ĭVDID - DVD player ID. Notifies the DECI2 manager when the host interface (i.e. Purpose unknown.ĭECI2HSYN - DECI2 Host SYNchronization driver. Purpose unknown.ĭECI1DRP - DECI1 PIF/mini-RA driver. Purpose of its existence is not known.ĭECI1DR1 - DECI1 H1500 driver. Only used by the OSDSYS of the SCPH-10000 and SCPH-15000, probably retained for backward-compatibility.ĭ2ELOADP - DECI2 ELOADP extension (ERX module support).ĭECI1 - DECI1 manager. Only does something useful on TOOL units.ĬLEARSPU - Seems to clear/reset the SPU, but is known to cause crashes under some conditions.
Seems to be for network configuration, but why?īOARDINF - reads in the DSW602 board's ID and sets up the values for Boot Modes 6 and 7.
Despite its similar name, it is very different from the full ATAD module.īNNETCNF - not entirely sure what this is for, but it appears in the PS3's PS2 ROMs. Again, I’ve included all different regions/types just in case, you only need to use 1.Here is an overview of what is contained in a PS2 ROM (including TOOL, DESR/PSX, ps2emu/ps2gxemu/ps2softemu (PS3), System 246 and System 256).Īn updated version is available here: ContributorsĪDDDRV - Adds support for the DVD ROM (rom1:), via ROMDRV.ĪDDROM2 - Adds support for rom2 (which contains a Chinese font file), only for Chinese consoles (SCPH-50009).ĪTAD - The DEV9+ATAD(+Flash device) combo driver. Open your emulator and if required, specify the BIOS File. Each emulator is different, ensure to check the READ ME for specific instructions. In some cases, place the file in the same folder the Emulator is located. Unzip the the file(ps2_bios.zip) and place whatever BIOS file you need (this has them all) in the same folder the PS2 ROMs are located in.
