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 wont work. You're getting the compatibility of the 2.60 software emulator with all of its bugs.

Enable Playstation 2 on non BC's

[Getting Playstation 2 Software Emulator working]

XMB Game Settings non BC/BC,patched

Service Mode in relation to PS2 emulation tests

• Service mode resets display settings (on default it uses HDMI with composite on MultiAV connector) - this means that users of Component cables can get garbled screen / no display output (in tests below, the primairy screen) unless using composite wiring/screen (in tests below, the secondairy screen).

• Service Mode also resets user presets like disc autoboot, so it needs to be disabled again if needed.

• Any made Virtual Memory Cards previously will be removed and you will have no access to them, nor be able to create one.

• When PS3 is switching to PS2, connection with Sixaxis / Dualshock 3 will be lost (even when using USB wired connection). In some cases easily resyncable by using PS button, but in other cases the leds stay off and the controller cannot be used (until ps2 mode is exited or console rebooted)

• As a workaround for above wireless controller issue, you can use an USB2PS2 converter and connect an old PS2 / Dualshock2 controller.

tests on 2000 series PS3 Slim

Testplatform:

SKU: 2000 series slim (minver 2.70)
Firmware: 3.55 'Rogero 3.4' mmap114+peek/poke but no SS-patches
Memorycards: MC:PS1 in slot1, MC:PS2 in slot2.
Mainscreen: Component+Composite 576i+P/720i+P//1080i
Sec.screen: Composite 576i
48 titles tested (PAL disc on PAL SKU) // Euss

• Without Factory Service Mode : gives "Incompatible Data" when inserting PS2 disc

• When enabling LV2Patcher without factory service mode (patch4 set as http://pastie.org/private/jp8zhvuocjz95cfrjm0uzg) : no changes in XMB:Game (still only PS upscaler/smoothing, no PS2 mention at all)

• When enabling LV2Patcher without factory service mode (patch4 set as http://pastie.org/4355919) : gives XMB:Game PS2 smoothing/upscaling options, it also make an inserted disk to be seen as PS2 format. Still same problem of ¨incompatible title¨ and loss of BT/settings. Also after returning to XMB, it no longer sees the disc as PS2 format but as incompatible data (which suggests the lv2 patch is undone, as lv2 is reloaded when returning from the ps2 lpar)

• Using boot_ps2.pkg without factory service mode : no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).

• With Factory Service Mode enabled (there are no Xmb options to combinetest with LV2Patcher or boot_ps2.pkg): gives ´PS2 disc´ detected at disc icon, but starting gives: resetting of date/time/displayoutput (effectively disabling my mainscreen), then all connection to any bound bluetooth device is lost, even when connected via USB (needs multiple PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).

In short: boot_ps2.pkg and Factory Service Mode seem to enable simulare (it tries to boot it) while boot_ps2.pkg gives you more options e.g. using LV2Patcher. Perhaps hardswapping out all the dev_flash ps2 emu files for the same software only emulator would circumvent the 'incompatible title' message.

Second test: FW 2.70/3.15

Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using boot_ps2.pkg gives title not supported error message like "This title is not currently compatible with the PS3 system".

Third test: FW 3.55 OtherOS++22GB (with SS Patches)

Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using boot_ps2.pkg gives blackscreen lockup, not reacting on PS button, or powerbutton, requiring removing powercord.

tests on CECHC04 (partial BC)

on 3.41 or on 3.55 in normal XMB mode (no disc icon in XMB): boot_ps2.pkg gives no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the "The system was not turned off properly" as if it had experienced poweroff and from there booted back to XMB. It then returns to the XMB, but first gives an error screen, mentioning 0x80028F17 occured (PS2 mode error 0x80028F17 "An error occurred during the start operation (80028F17)," PlayStation 2 disc Boot Error, also related to PS1 PSN games.)

on 3.41 or on 3.55 in normal XMB mode (disc icon in XMB): boot_ps2.pkg gives resetting of date/time/displayoutput (no output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation). The game is playable on secondary screen, and exit to XMB with holding PS button goes without 0x80028F17 errors, but does give the "The system was not turned off properly" error.

no disc icon:

• Medal of Honor: Rising Sun
• Half-Life

disc icon:

• Hulk
• Second Sight
• Silent Hill 3
