To quote: Getting PlayStation 2 Software Emulator working

Method (on Firmware 3.55, without! Cobra-USB Dongle or Downgrade) for all consoles (fat & slim).

1. Replace following files on your consoles /dev_flash/ with the ones included in this archive p3dwik-ps2compatfiles.rar
2. Get into Factory Service Mode (FSM Tool/Dongle)
3. Insert your Original PS2 Game Disc
4. It will run.

Note: Backups won't work. You're getting the compatibility of the 2.60 software emulator with all of its bugs.

A possible compatibility lists:

  • ps3devwiki.com/wiki/Talk:Emulation#PS2.2FPStwo

PS2 Compat. flag

All consoles have hardware information. In GameOS you can call Lv2 Syscall 393 (0x189) sys_sm_get_model to get your consoles information. In Lv1/Hypervisor its in the repository nodes sc 0x5B lv1_get_repository_node with Parameters "sys","hw","config" usually noded as "sys.hw.config#0" or something.

Hi I just make a debug app that use some syscalls to do a reset into PS2 Lpar like boot_ps2 does, it should work on dex 4.11 or 4.20 but in these fw there is ps2 netemu instead of softemu so i need someone with an original disc of playstation 2 inserted on bd-drive and launch this test app and see what happens.

I am on 4.11 DEX but i don't have any original disc from PS2... This is basically the same thing that boot_ps2 does on 3.55 but there is a new emu file on dex 4.11 or 4.20 introduced on 3.70 with the use of PS2 Classics on PSN... This is not brick-risk, thanks to anyone who help me with this. Greetings...

1st - Download the file
2nd - Copy the file PS2 Evo v1.0.pkg to the root of a USB drive formated in FAT32
3rd - Install the .pkg from *Install Package Files*
4th - Insert a original PS2 disk on the BD
5th - Run the app and enjoy

Sad to tell you this, but Nope .... That Retro column if for emulators of much older consoles (Like FCEU to play old NES roms)

So under the Retro multiman are you able to play PS1 and PS2 back ups? I have a 80gb BC model and I was wondering if I could play my Ps2 back ups from multiman.

  • mM is now even faster
  • Installing PKG files from /dev_hdd0 now doesn't require copying and losing time and space (takes less than a second)

  • Fixed problem with split games in stealthMAN
  • InstallPKG [Singstar Replacement] available (updated)

MultiMAN v04.17.00 is now available from deank with both speed optimizations and reduced PS3 RAM usage. Be aware the Stealth version (StealthMAN) isn't completely safe as Sony (or other users) can still see when you 'Install Package Files' (as pictured below) at the moment.

  • multiMAN ver 04.17.00 BASE CEX (20121220).pkg
  • multiMAN ver 04.17.00 BASE DEX (20121220).pkg
  • multiMAN ver 04.17.00 BASE CEX STEALTH (20121220).rar
  • Latest versions of mmRAS and mmRAS_server by aldostools
  • Latest version of installPKG (with support for /dev_hdd0/PKGTMP)
  • Showtime, bdRESET, stDISC, gameDATA, lastGAME as usual

Here are the changes from 04.16.02/03/04/05/06 to the latest:

  • Improved overall speed of all functions and GUI
  • Data Test/Verify functions now take fraction of the time compared to previous versions
  • Improved 'Verifying data' of USB games by a factor of 50
  • Improved scan before copying a game/folder
  • Improved loading folders in mmOS
  • Improved just a bit deleting games/folders
  • Greatly improved loading content when browsing PS3 HDD/USB drives in game modes
  • Loading Retro ROM/Video/Photo and ISO folders while browsing PS3 HDD/USB is now about 15 times faster
  • Added "Friendly" name option in "Settings"/"Network Servers" for /net_host parties
  • Fixed over-scrolling when browsing through large number of entries
  • Increased max number of entries in game modes by 50% to 3072 (from 2048)
  • Improved speed when copying games/files from/to USB HDDs
  • Improved speed when copying games from PS3 Game Discs
  • Improved speed when copying/browsing folders via FTP (LIST/MLSD)
  • Added support for up to 99 pkg files in the [* Install Package Files] queue
  • [* Install Package Files] function will scan /dev_hdd0/PKGTMP and will MOVE the queued pkg files from this folder (saving HDD space by not copying to temp location)
  • mmOS will now honor the "Verify USB Games" setting when starting games from icons/shortcuts/game-folder
  • Scanning for active USB storage devices is now performed in the background and will speed up loading games on 4.xxCFW
  • Verifying games in now performed in the background (when possible) to avoid delays when loading games

While on the 'improvement' track I decided to remove and completely rewrite another major function in mM - copying folders/games. Currently the memory used by the new function is down to 6MB (from 12MB - used to be 32MB in the beginning). While at it I added the double progress bar so you can monitor the progress for each file and the overall progress.

I used LittleBigPlanet game as a test/reference when I started improving things last week and finally got about 15-30% speed increase.

8343MB (240 files):

Before the optimizations:

  • HDD->USB = 13:20min (800 seconds) (~10.4MB/s)
  • USB->HDD = 11:30min (690 seconds) (~12.1MB/s)

After the optimizations:

  • HDD->USB = 10:30min (630 seconds) (~13.3MB/s) (about 28% faster)
  • USB->HDD = 08:30min (510 seconds) (~16.4MB/s) (about 35% faster)

Of course with games with less files the transfer speed hits the limit of the internal HDD (~30MB/s) or the external USB (~20MB/s) like for example copying GT5 (14056MB in 19 files):

  • HDD->USB = 15:05min (905 seconds) (~15.5MB/s)
  • USB->HDD = 11:58min (718 seconds) (~19.6MB/s)

Copying from PS3 Game Disc is at ~8.4MB/s (which is the max. read rate of the ps3 bd-drive). It may not look THAT much faster, but probably with larger games the saved time will be a lot more. 5 or 15 mins saved is still something.

p.s. To those who wonder about the latest speed improvements - you may remember my posts during the year: "Saved 5MB or RAM here... 20MB or RAM there... another 15MB RAM saved..." so finally I found time to utilize the resources I managed to free. Now I had to rewrite a lot of functions from scratch and optimize them as much as I can. The result is more speed and stability.

Here is how I do it in installPKG and mM: Method of calling to install "/dev_hdd0/PKG/TestFile.pkg":

The example doesn't include "copying" the PKG to a temp location if using USB HDD. This one just moves the file from one location on the internal hdd to the game_pkg folder. It is very simple (just 20-30 lines or so) and doesn't need explanation - it only creates d0.pdb and the ICON_FILE.
u64 is_size(char *path)
struct CellFsStat s;
if(cellFsStat(path, &s)==CELL_FS_SUCCEEDED)
return s.st_size;
return 0;

int exist(char *path)
struct stat p_stat;
return (stat(path, &p_stat)>=0);

void array_to_file(char *_path, unsigned char* _buf, int _size)
FILE *flistW;
flistW = fopen(_path, "wb");
fwrite( _buf, _size, 1, flistW);

u8 bubble_pkg( char* _path, char* _file)
char task_path[512];
char temp_path1[512];
char temp_path2[512];

cellFsMkdir((char*)"/dev_hdd0/vsh/game_pkg", S_IRWXO | S_IRWXU | S_IRWXG | S_IFDIR | CELL_FS_S_IFDIR | 0777);

for(u8 n=0;n
