*Notes
**The colors used at the cells of the left column in the table are just temporal, later willl be needd to decide if using them, how many to color, and the color palette used in them... by now works a bit as an small hint of the complexity of the commands, and a rought way of grouping them
**This table was not intended to replace the other in frontpage, there is some info in the other that is not here, and here there is some info that is not in the other (and this is a problem), what happened is this table started growing and is at a point where can be done two different things with it, we can step back and simplify it (by removing the columns at right and the redundant info with the table of frontpage), or we can continue expanding it by adding here the info of the other table in frontpage

====ps2_netemu cmd 0x01 funct_offsets_table====
ps2_netemu contains a table (with entry_length=8 and entry_number=variable) where are listed the function offsets used by command 0x01

This table is used to assign a funct_id to a funct_offset. The funct_id is given by the position of the entry in the table, so the first entry in the table is funct_id=0x00, second entry is funct_id=0x01 and so on

The purpose of this table is to be able use the same funct_id values in the external CONFIG files for netemu, this way even if the offsets changes (internally inside the ps2_netemu.self file structure) in between versions the funct_id will be the same. The other ps2 emulator types doesnt have this table (doesnt needs it because doesnt uses external CONFIG files)


*funct_offset_table location by ps2_netemu versions:
**offsets v1 (the table contains the same data)
***Firmware:370-371 offset:0x897ED8 length:0x1C8
***Firmware:372 offset:0x897ED8 length:0x1C8
***Firmware:373-374 offset:0x897ED8 length:0x1C8
**offsets v2 (the table contains the same data)
***Firmware:400-401 offset:0x8970E8 length:0x1C8
**offsets v3 (the table contains the same data)
***Firmware:410-411 offset:0x8971E8 length:0x1C8
***Firmware:420-423 offset:0x8972F8 length:0x1C8
***Firmware:425 offset:0x8972F8 length:0x1C8
**offsets v4
***Firmware:? offset:? length:?
**offsets vX
***Firmware:478-482 offset:0x8063f8 length:0x1E0

==Game CONFIG commands (notepad and worklog)==
All info here related with commands needs to be moved to frontpage at some point

===ps2_netemu command 0x1===
There are some additional internal patches using CONFIG cmd id 0x01, using subs not available in 0x3B list

===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.

==== 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) // [[User:Euss|Euss]]

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

* When enabling [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ 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 [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ 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 [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg 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 [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher] or [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg 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: [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] and Factory Service Mode seem to enable simulare (it tries to boot it) while [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives you more options e.g. using [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ 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 [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg 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 [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives blackscreen lockup, not reacting on PS button, or powerbutton, requiring removing powercord.


===== considering titles to test =====

* http://tortuga-cove.com/forums/viewtopic.php?f=57&t=530
* http://us.playstation.com/support/compatiblestatus/index.htm

These have no listed issues:
* Half-Life
* Hulk
* Medal of Honor: Frontline
These have minor issues listed (but should still play):
* Silent Hill 3
* Second Sight

==== 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

==== Renaming ps2_netemu to ps2_emu ====

Tested renaming ps2_netemu.self to ps2_emu.self on CECHB01/rogero 4.21 with dev_blind mounting via multiMAN but boots to black screen, no disc activity, but controller shuts off and is synced. No PS button menu or anything.

boot_ps2.pkg boots, no disc activities, then throws up an error depending if the file is resigned for 4.21 or not. (tried both a resigned and the existing version)
