== GPU related info ==
== Command IDs mapping ==
<pre>
All the PS1 emulators have some game settings hardcoded inside them organized in a table using a hierarchy, pretty much the same structure used by ps2_gxemu.self and ps2_softemu.self to store the CONFIGS<br>
Highly recommended to visit site below to understand this info:
There is a point of the hierarchy where is indicated the number of commands and the offset where are located. Every command is composed by ID[4] and data[4] (where the data coould be another offset to load more data from a deeper level of the hierarchy)<br>
http://problemkaputt.de/psx-spx.htm#gpustatusregister
That IDs differs in between the PS1 emulator versions because are not a direct ID, it seems every ID is mapped to a different ID (probably static and common for all emu versions) in a separated table

=== ps1_emu vs ps1_netemu GPU emulation differences ===


In some cracktros (Spyro 3, Sydney 2000, NFS Porsche 2000) the GP0 command E4h (E4080200) draws the image on the wrong coordinates, causing the frozen image of the zoomed PS1 licence screen. According to this [https://psx-spx.consoledev.net/graphicsprocessingunitgpu/#gp0e4h-set-drawing-area-bottom-right-x2y2 info], that command does make use of the newer 2MB VRAM GPU coordinates. Restricting the drawing area to the lower coordinates does fix the image. It looks like a lot of emulators are affected by this, either the Sony ones (ps1_emu on PS3, PS1 on PS2 hardware emulator, POPS on PSP) or the homebrew pSX 1.13. The ps1_netemu is displaying the image correctly. Does it mean the ps1_netemu emulate a different, newer GPU or just increase the emulation accuracy in general (assuming these cracktros work fine even on the oldest PSX released EDIT: I have found reports they are picky even on the original PS1 hardware too.)?
====How hardcoded config is read based on ps1emu.====
* Yes, this should fail also on old PS1 GPU. I can also confirm that PS1DRV (at least before deckard PS2 models) emulate old GPU model.
Like mentioned above config is created from 2x u32 values. Lets call first value command, and second value param.<br>
As for PS3. ps1_emu, and ps1_newemu emulate old GPU, ps1_netemu emulate new GPU at least partially. Also small tip, all emulators have pair of 2 embed
Command is used to calculate address for param, and only param is stored on obtained address.<br>
SPE ELFs. One is SPU emulator, second is GPU emulator. All of them have debug symbols.  
Emulator then check for params, and if found (usually when not zero) apply settings based on them.<br>

====Per game hash calculation====
ps1_netemu
Hash is calculated using the data contents only (2048 bytes or 0x800h) of the sector 16 (beginning at the 0x9318 of the RAW/2352 image). Every single byte is used in the process. Calculation code does start at 0xC1658 in the ps1_netemu from 4.88 firmware.

==== Allow non encrypted ISO.BIN.EDAT and skip signature check (RPCS3 only) ====
For easier config testing. Patch allow to use unencrypted ISO.BIN.EDAT so we don't need to mess with klic. Also ECDSA signature at the end of file is no longer required. So we can ftp configs as is, for faster testing. Warning! This patch break official ps1_classics.

== Ps1_netemu Commands Info ==
 
=== External Configs ===
 
Loading external commands is be possible in ps1_netemu. From this we can also figure out that sony call those configs "ad hoc params" which can be little bit misleading. Emulator expect them inside ISO.BIN.EDAT file. Offset depend if "optional header" exist or not. Values are little endian.
The offsets below are the offsets from the start of the PSISOIMG section. This data starts at absolute file offset 0x424 for single disk games that do not use a PSTITLEIMG section. For games that do have a PSTITLEIMG section, the absolute offset will be shifted by 0x400 bytes, i.e. to offset 0x824 and similar.
* Offset 0x424 Config revision in bcd format, that need to be higher than DB from emu (11624 for 4.86). Safe to use 0x200000.
* Offset 0x42C first config command
* Offset 0x430 param for first command
* This repeats 8 times as only 8 commands is supported.
* Command 2 is unsupported.
* Command 0 is unsupported because $ony made mistake in parser.
* Command 0x17 is supported, but there is different official way to inject it, and it is libcrypt key so there is no point to do it this way.
This probably repeats for multidiscs, but for now let's figure out single discs first.
<br>Function that search for configs look like this:
case 9:
  if ( *(&0x161FD80) ) 1570FA0(base) + AEDE0(offset in ISO.BIN.DAT or PSISOIMG? ) = 161FD80 in 4.86 ps1_netemu
  {
    cfg_rev = get_cfg_rev_from_PSIMG();
    db_rev = get_titledb_rev();
    decimal_16 = ret_32() >> 1;
    tty_print("ad hoc param: %x <%x>\n", cfg_rev, db_rev);
    if ( decimal_16 )
    {
      low_rev = cfg_rev < db_rev;          // Check is opposite to ps2_netemu, only config version higher than included db will pass.
                                            // Which mean config need to be higher version than emu database.
      for ( i = 0; i < decimal_16; i += 2 ) // up to 8 configs supported (8 commands + 8 values)
      {
        cfg_command = read_cfg_from_PSIMG(i);
        _cfg_value = read_cfg_from_PSIMG(i + 1);
        if ( cfg_command - 1 <= 0x3B )      // max cfg nr 0x3C
        {
          v245 = cfg_command >> 28;        // Most likely check for wrong endianess. Configs are LE and are byte reversed before we end up here.
          if ( low_rev || v245 || cfg_command == 2 )// cfg 2 unsupported (replaced in later PSIMG rev with subchannel data), or old config rev, or v245.
          {
            tty_print("%x: %2d=0x%08x ***\n", v245 & 0xF, cfg_command, _cfg_value); // Ignore cfg
          }
          else
          {
            cfg_value = _cfg_value;
            tty_print("%x: %2d=0x%08x\n", 0LL, cfg_command, _cfg_value);
            WriteInternalConfigValue(cfg_command, cfg_value);
          }
        }
      }
    }
  }
 
=== Command IDs mapping ===
The command IDs differs in between the PS1 emulator types and versions because are an indirect ID, it seems every command ID is mapped to a static ID in a separated table<br>
The command ID's varies in between firmware versions, most probably because new functions was added every few versions, reorganized, etc... and this changes created a "displacement" of the old commands that causes them to increase his ID<br>

At the time of writing this we dont know how to map that variable ID's to an static ID (that could be valid for all firmware versions), so by now in this list is needed to indicate the firmware version where the command ID was found<br>

Coincidentially there are a few commands that preserves his ID in between emulator types and revisions, most probably is because are the first commands implemented and the variable ID given to them is a very low value, so always was kept at a low position in the commands list and was not disturbed by the modifications made to the other commands.
Coincidentially there are a few commands that preserves his ID in between firmware versions, most probably is because are the first commands implemented (up to netemu command 0x04)) and the variable ID given to them is a very low value, so always was kept at a low position in the commands list and was not disturbed by the modifications made to the other commands.
<br><br>
According to internal tables (4.86):
* ps1_emu support commands up to 0x15
* ps1_newemu support commands up to 0x18
* ps1_netemu support commands up to 0x3C
Beside functions that read command params directly, every emulator have function (madeup name) ReadInternalConfigValue(u32 command_id). This function take command_id as only variable, and return param in r3 for selected command. This is used widely to read command params, that include libcrypt commands.
<br><br>
Function mentioned above is placed on (in emu memory, 4.86):
* ps1_emu 0x10638
* ps1_newemu 0x12F54
* ps1_netemu 0xB65F0


=== Command 0x00 (netemu 3.40 up to 4.88) ===
*Valid values found
**0 = ? (used by SCPS-18011 Um Jammer Lammy, and SLPS-01818 Langrisser IV & V Final Edition [Disc1of2])
In Um Jammer Lammy is used together with command 0x13, so it was a bit doubtful if it was a mistake. But Langrisser IV & V Final Edition [Disc1of2] uses it too and is the only command used by this disc, so it "should" do something. Um Jammer Lammy in netemu 3.40 was fixed only with command 0x0/0x0 (id/data)
*Um Jammer Lammy (SCPS-18011) uses somewhat new external config revision (11580) in official classic's external config, but only uses command 0x13. Keep in mind the game was released Febuary 27, 2008, so package was possibly updated with new config at some point, and then in internal table, so maybe it once had a different config command in config table and 0x00 nullified it. Langrisser IV (SLPS-01818) has old config revision (5713) and uses command 0x03 set to 0x3E8, so just default. Maybe internal config for Langrisser IV is empty config just to also nullify external config? --[[User:Mrjaredbeta|Mrjaredbeta]] ([[User talk:Mrjaredbeta|talk]]) 03:32, 1 September 2023 (CEST)

There are only 3 games using this command and are libcrypt protected games:, Crash Team Racing (SCES-02105), MediEvil (SCES-00311), and Vagrant Story (SLES-02754)<br>
The command data contains an offset that points to an area where are stored a list of sectors (4 bytes each), there are only 3 games using this command and are libcrypt protected: MediEvil (SCES-00311), Vagrant Story (SLES-02754), and Crash Team Racing (SCES-02105)<br>
The command data contains an offset that points to an area where are stored a list of sectors (4 bytes each). When the emulator starts reading the list it doesnt knows how long is it so it reads groups of 4 bytes consecutivelly until it finds the value 00000000 that works as a terminator, the presence of this terminator at the end of the sector list is mandatory. Worth to note that list is more extensive than redump libcrypt one, but they match to some extend. Probably redump store only sectors really needed to run game correctly, while Sony decided to keep them all. Command is used only with LC1 games (Redump is wrong about medievil, is LC1).<br>
The libcrypt protection is related with subchannel data stored by sectors, in redump.org this data is managed with the SBI files, displayed in a hexeditor view in each specific game page. If we convert the data from the official format to decimal and we compare it with the sector numbers in the redump.org SBI file it can be seen all the libcrypt protected sectors from the SBI file are included in the official format<br>

The official format seems to include a lot more sectors which purpose is unknown<br>

There seems to be way to supply that data/command from external file. Some research by "Fedor Wearing A Fedora" [https://www.psx-place.com/threads/ps1-libcrypt-support-on-ps3-official-emus-research-thread.35836/page-13#post-318218 here] and [https://www.psx-place.com/threads/ps1-libcrypt-support-on-ps3-official-emus-research-thread.35836/page-13#post-318506 here]<br>

* It seems there is a problem with LC games using the third scheme mentioned [https://problemkaputt.de/psx-spx.htm#cdromprotectionlibcrypt here]. After reading the data contents of subchannel Q, the CRC-16 value is not read at all, but calculated on its own by the driver instead. It does break LC games using this particular scheme (web-found confirmed issues with Ape Escape and Final Fantasy VIII). All three games that are meant to work with this command does use these LC sectors. I think this command was meant to resolve this issue, just a guess.--[[User:Agrippa|Agrippa]] ([[User talk:Agrippa|talk]]) 20:06, 12 June 2022 (UTC)

Substrat cycles from mdec_block_copy_out_callback delta. When mdec is decoding blocks, copy out happen on every completed 6th block. This is hardcoded to take 0xB00 (2816) cycles in ps1_netemu. By using this config we can make this value less than default, which in turn "overclock" mdec decoding as every 6xblock will be decoded faster. Duckstation by default use value 0xA80 (2688 (448 x 6 blocks)). So to make config that will replicate this behavior we need set config value to 0x80 (0xB00 - 0x80 = 0xA80).
*Default value: 0

*Valid values range: 0x000 - 0xB00

Sync order of controllers is always the same regardless of parameter set (1/1-A, 2/2-A, 1-B, 2-B, 1-C, 2-C, 1-D). Therefore, change is only reflected internally in emulated game.

Note from nocash docs about Vertical Interlace: ''"'''Interlace must be enabled to see all lines in 480-lines mode''' (interlace is causing ugly flickering, so a non-interlaced low resolution image is typically having better quality than a high resolution interlaced image, a pretty bad example are the intro screens shown by the BIOS).''"<br>
This suggest that games which eventually need 0x31, 0x02 will be ones that send GP1 commands with active bit 2(Vertical Resolution 1=480) and 5(Vertical Interlace) at the same time. Otherwise image will be cropped, or badly interlaced. FF8 use this on "Published by..." screen, you can notice weird interlacing when subtitles fade-in without command.

== Possible Cobra implementation issues ==
Every CFW which use cobra module potentially can be affected by nasty bug that is there probably even before 7.00.<br>
So the deal is patch in cobra that allow skip region check, example based on ps1_emu.  


=== Command 0x3B (netemu 4.83 up to 4.88) ===
<pre>SprxPatch ps1_emu_patches[] =
PS1 SPU DMA related config. Seems to change some cycles calculation.
{
*Default value: 0
{ ps1_emu_get_region_offset, LI(R29, 0x82), &condition_true }, /* regions 0x80-0x82 bypass region check. */
*Valid values: 0/1
{ 0 }
};
</pre>


== Ps1_emu Commands Info ==
While patch actually skip region check, is also skipping part of code where region of ps3 is stored for future usage. And probably set whole emulation to JPN<br>
This can be important because function that cobra patch, probably is responsible for selecting region of ps1_rom. <br>
There is a string in emulator JJJJAEJEAEJJEJJA which seems to be selector for bios/rom region based on target ID ([[Product_Code]]).
<pre>J    J    J    J    A    E    J    E    A    E    J    J    E    J    J    A
0x80 0x81 0x82 0x83 0x84 0x85 0x86 0x87 0x88 0x89 0x8A 0x8B 0x8C 0x8D 0x8E 0x8F</pre>


=== Command 0x15 (ps1emu 4.83 up to 4.88) ===
Hard patch to 0x82 potentially lead to known PAL games frame pacing issues, and to desynced audio, and maybe more. While i can't test that i'm 100% sure that better solution here will be read third character of Title ID from SYSTEM.CNF file of disc/iso, and then patching same place with<br> ps1_emu_get_region_offset, LI(R29, title_id_based_region), &condition_true . <br>
*Valid values found:
Generally if title have E then patch to ANY EU target ID, similar for US, for titles where U or E isn't found just use default J target ID.
**3 (launch game using ps1_netemu)
Above is based on static elf analyse, so i can't tell 100% that is an issue, but it looks like it in emu code.
**Different values are ignored


== Ps1_newemu Commands Info ==
* Is that patch being applied every time, even on the PAL region console? I have never noticed any issues and I was playing the PAL games mostly. The only thing I noticed is the slowed and pitched down licence screen when the PAL game is launched through the ps1_netemu. --[[User:Agrippa|Agrippa]] ([[User talk:Agrippa|talk]]) 17:40, 6 January 2022 (UTC)


=== Command 0x18 (ps1newemu 4.83 up to 4.88) ===
== ps1_emu vs ps1_netemu emulation differences ==
Supposed to launch game using different emulator, but all paths do nothing.
*Valid values found:
**3 (Do nothing, but with print! [https://imgflip.com/i/7x4j2p 1])
**Different values do nothing


== Known bugs ==
In some cracktros (Spyro 3, Sydney 2000, NFS Porsche 2000) the GP0 command E4h (E4080200) draws the image on the wrong coordinates, causing the frozen image of the zoomed PS1 licence screen. According to this [https://psx-spx.consoledev.net/graphicsprocessingunitgpu/#gp0e4h-set-drawing-area-bottom-right-x2y2 info], that command does make use of the newer 2MB VRAM GPU coordinates. Restricting the drawing area to the lower coordinates does fix the image. It looks like a lot of emulators are affected by this, either the Sony ones (ps1_emu on PS3, PS1 on PS2 hardware emulator, POPS on PSP) or the homebrew pSX 1.13. The ps1_netemu is displaying the image correctly. Does it mean the ps1_netemu emulate a different, newer GPU or just increase the emulation accuracy in general (assuming these cracktros work fine even on the oldest PSX released EDIT: I have found reports they are picky even on the original PS1 hardware too.)?
* Yes, this should fail also on old PS1 GPU. I can also confirm that PS1DRV (at least before deckard PS2 models) emulate old GPU model.
As for PS3. ps1_emu, and ps1_newemu emulate old GPU, ps1_netemu emulate new GPU at least partially. Also small tip, all emulators have pair of 2 embed
SPE ELFs. One is SPU emulator, second is GPU emulator. All of them have debug symbols.

==== Cdr int reads with nonstandard index ====
<pre>
Emulator ignore interrupt flag register and interrupt enable register reads if cdrom index is 2, or 3. Reads like that are undocummented behavior, but confirmed to be successful on real hardware. Also Nocash docs, and Duckstation source handle that correctly, and i remember there are games which used that.

Always set bit 9 in GP0 E1 command to 0. Patches apply to SPE PS1 GPU emulation program. Based on 4.86, but should be valid for all firmwares since 4.6x<br><br>

0xD8264  clrlwi    r0, r0, 31  #hex 54 00 07 FE
This change cdrom.index & 3, into cdrom.index & 1. This way index 2, and 3 will be respected as 0, and 1. Sadly there is no easy hex pattern, so patch need to be done manually. Memory offsets for 4.86.
 
==== Bad encoding of malformed conditional branch 0 ====
Emulator don't ignore few bits, and expect they are 0. While real hardware seems to don't care about them.

Problem start when bits 17,18,19 are not zero. Emulator don't clear those bits, and explicitly check only for 0x0,0x1,0x10,0x11.

Correct solution here will be patch to AND r24 with 0x11 first, to clear meaningless bits before comparison.
This is reason why emulator fail this "Branch Advance" CPU test: https://emulation.gametechwiki.com/index.php/PS1_Tests#CPU . Possibly standard "Branch" test is failed for the same reason.
