Memory Card Emulator for PlayStation 2

Part of HD Homebrew Project at PSX-SCENE.

HD_Project is the frontend (GUI) for the memory card emulator. It allows to dump real memory cards using new MCMAN & SIO2MAN modules from a game disc and can find IOPRP images automatically to launch a game. The following file contains ELF and full source code.

MCS2EMUL is a generic loader for the memory card emulator. It uses FAKEBOOT module to inject the emulator along with other required modules into a game and block IOP reset. The loader can be launched with PS2Link program while a game disc is in console's drive to start a game with the memory card emulator.

Typical usage: ps2client -h ps2 execee host:mcs2emul.elf "-ioprp=cdrom0:\IOPRP300.IMG;1" "cdrom0:\SLUS_212.44;1"

The following files contain MCS2EMUL.ELF:

USBMCEMU.ELF is a version of loader&emulator for use with USB mass-storage devices. It's similar to MCS2EMUL.ELF for HDD.

Typical usage: ps2client -h ps2 execee host:mcs2emul.elf "-ioprp=cdrom0:\IOPRP300.IMG;1" "cdrom0:\SLUS_212.44;1"

MCSIOEMU is the memory card emulator IRX module. It hooks SIO2MAN's interface to handle SIO2 memory card commands. The emulator uses memory card image file(s) on a PFS partition to emulate a memory card. The following file contains IRXs and their source code.

MCSIOEMU.IRX v0.6 (Jun 10 2007)
MCSIOEMU.IRX v0.5 (May 20 2007)
MCSIOEMU.IRX v0.4 (May 04 2007)
MCSIOEMU.IRX v0.3 (Apr 26 2007)
MCSIOEMU.IRX v0.2 (Apr 20 2007)

MCDUMP is IRX module that can be used to copy a real memory card to a single file. It will dump the whole card to a file, i.e. memory card image will be produced. The image file differs from virtual memory card file format used by PCSX2 (PlayStation 2 emulator for PC) since PCSX2 saves "spare data" while neither MCDUMP nor MCSIOEMU don't write "spare data" to a file. The difference between these image formats can be compared with ISO&BIN file formats for CD images. The MCDUMP is supposed to work with new MCMAN modules while its compatibility with the default MCMAN ("rom0:MCMAN") is not guaranteed. Furthermore, MCDUMP can detect non-standard memory card (16MB, 32MB and so on) with the default MCMAN module so it will always assume the memory card is a standard 8MB card unless it uses a new MCMAN module.

Typical usage: ps2link -h ps2 execiop host:mcdump.irx -port=0 host:memorycard0.bin
