Support for USB devices seems to be limited comparing to other available emulators. Although PS2 side of USB subsystem seems to be fully implemented. IOP emulator in SPU handle USB HW registers addresses and generate interrupt for PPU which later handle RW to mentioned registers in similar fashion to ps2_emu/ps2_gxemu. PS2 side of things can be disabled/enabled using one byte, when disabled USB writes are ignored, and USB reads return 0. Initial state is unknown. Emulator seems to accept HID controllers and use them as DS3.

Multidisc info bytes:

Second byte: Discs count (0-9), when 0 or 1 emulator don't enable multidisc mode.
Third byte:  Which disc in set is this one (0-8 for discs 1-9)
Fourth byte: That one is optional, but very important. When set to 1,

|0x17|| NFS HP2 fpu rounding fix.
|0x17||  
  Check if a0 == 0x8000 (32768), apply config if true. Config is little bit more complicated than it should, emu flush all fpu regs to memory just to modify one field in altivec vector register.
  condition r18 == 0x8000
  When condition is met ps2 cop1 f08 register is modified from 0x40490FDB to 0x40490FDA, this result in next operations to end up as negative 0.0 (0x80000000) instead of just 0.0 (0x00000000).
  setting:
Seems to trigger when loading of stage or loading of attract mode is close to finish or done.
  stores 0x40490FDA somewhere
Note: 0x40490FDA (3.14159250) is the highest float approximation to π in hexadecimal without going over the value.<br />
Probably can improve FPU accuracy for some games.

*mode 0 - Replace 32 bit of EE memory. Params are EE offset, original opcode, replace opcode.
**1 [Deadly Strike]
*mode 1 - Write jr ra, li v0, xxxx to selected memory range. Params are EE memory start address, original opcode, u16 counter, u16 value for li, v0 xxxx
**2 [Dragon Force]
*mode 2 - NOP memory at selected range. Params: start address, end address, unused (can be anything, but is required to align config).
Problem: Original opcode validity check is performed before testing config for special cases. Thus making mode 2 almost inaccessible.<br>
Solution: We can patch that one line of code by the same 0x0A config. So if we want to nop region from 0x100000 to 0x100080, first we need to patch 0x100000 to 0x100080 opcode. So check will pass, "simple" as that.

  Make VIF0 commands MSCAL/MSCALF/MSCNT/MPG/FLUSHE non instant. By default every VIF0 command take 1 cycle, so it's instant.
  Config value is added to another value, and stored later in negmem. For sure this is VIF0 related command, and can be VIF0 timing/cycle related.
This config give vif0 some timing sense.
When delta from config passed and vpustat vu0 bits are non 0 (so practically if vif0 is still running),
add 500 cycles and go on until next event test before doing anything on vif0.
This can also be used to ensure that next vif0 command won't run until delta from config passed.
Value from config is added to current r5900 cycles and vif0 will do nothing unless current cycles match new value.

Used by debug menu to print config revision. While every official and unofficial config use it, command is not mandatory. Debug menu will just print '''None''' as a config revision if command is missing. Official configs use this as a kind of debugging info to know minimal required emu revision.
This command works as a restriction, the emulator loads the config contents '''only''' if the '''emulator revision''' is bigger than the '''config revision'''. See: [[PS2_Emulation#PS2 Emulator Types and Revisions|PS2 Emulator Types and Revisions]]<br>
The goal of this restriction is to prevent the emulator to load a config containing unsupported commands, as example netemu command 0x50 is only supported since netemu revision 17495 (shipped with PS3 firmware 4.78 or newer), otherway if you try to load a config with a revision higher than your netemu revision the contents of the config are going to be ignored (as example when trying to load a modern config using commands higher than 0x41 in a custom firmware 3.70)<br>
In general is better to use a low revision with this command to lower the restriction as most as posible (oldest netemu revision is 15686), but '''only''' if the commands inside the config are not higher than 0x41, for a reference when creating custom configs check the table below, those are the minimal '''config revisions''' required that depends of the config commands contents

*Problems:
**The [[PS2 Official Configs|official NET config]] for Gradius V (SLPM-62462) uses config revision = 17498 (is the highest value ever found in a official PS2 classic config), this value is higher than any retail ps2_netemu.self revision, and is breaking the logic of the [[Template:Ps2configrev]] (used to calculate the PS3 firmware version required by the config). So either... 1) the description of this command written above is not accurate enought, or 2) the config has been "faked" to an incorrect revision, or 3) the config is real but sony made a mistake with the revision and the emulator is not loading it

Used to redirect to different ISO without game reset. First param is EE offset to hook, second param is some kind of mode selector, depending on that
Used to redirect to different ISO without game reset. First param is EE offset to hook, second param is ID size * 4. Emulator do some checks here, safe value is 3 (3 * 4 bytes), third value is ID in big endian hex ascii (eg. NPJD12345), additionally 0x4C expect own 00 00 00 00 terminator. To eventually end redirection use another 0x4C but with (offset, 0xFFFFFFFF, 4 * 0x00000000 . This config have very similar usage to 0x4B, just redirect to different iso, instead to different MC. Currently is unknown that cobra patched emulators support that config properly.
emulator later set mecha switch disc state:
  mode 0x01 = set disc switch state to 1 (on next mecha main loop it will emulate opening the tray).
  mode 0x02 = set disc switch state to 3.
  mode 0x03 = set disc switch state to 3. This state repeats because it work different way depending that emulated tray is closed or no.
  mode 0x04 = set disc switch state to 2.
  mode anything else = do nothing.
