Hello,

I have read the post, and I am a little bit confused.
As far as I understand the most points are the same as with the Psnee v7

VCC
SQCK
SUBQ
DATA
GATE_WFCK
GRD

But where are the points AX-BIOS, AY-BIOS and DX-BIOS on the PlayStation motherboards?

Obviously, the points AX-BIOS, AY-BIOS and DX-BIOS should be sought on the ROM BIOS chip (IC102)

Attached is the pinout of the 32 pin bios chip

p.s.: as it became known at the moment firmware contains a bug. if you want to use the console to listen to cd audio disks, you need to set a switch (Switch*(optional) on diagram) to disable bios patching. otherwise when you go into the cd player the console will hang/reboot. if you only plan to play, then this bug will not affect the launch.

As far as I can see, this bug still exists? Is there hope of a fix, or must we resign ourselves to using the switch?

As far as I know this bug has not been fixed. postal2201 did not have this bug, and I don't have the equipment to test it.

Ah OK. But does this bug happen on all PSXs? From a postal2201 video on YouTube it doesn't seem to since it starts the music player

Here is the video of postal2201 where he starts the music player in a PSone:

What can I do to help you guys fix the bug?
I really want to fix this because I noticed that the memory card manager does not work also.
I have a SCPH-7000.

Please, what are the pins: AX-BIOS, AY-BIOS and DX-BIOS on the IC102?

You should at least open the sketch file and look at it.

The pinout depends on the model of the console motherboard (which no one thinks it is necessary to specify).

However, here it is:

Code: Select all

//------------------------------------------------------------------------------------------------
//                         Select your console
//------------------------------------------------------------------------------------------------

//#define UC_ALL           // Use for all NTSC-U/C models. No BIOS patching needed.
//#define PAL_FAT          // Use for all PAL FAT models. No BIOS patching needed.
//#define SCPH_103         // No BIOS patching needed.
//#define SCPH_102         // DX - D0, AX - A7. BIOS ver. 4.4e, CRC 0BAD7EA9 | 4.5e, CRC 76B880E5
//#define SCPH_100         // DX - D0, AX - A7. BIOS ver. 4.3j, CRC F2AF798B
//#define SCPH_7000_9000   // DX - D0, AX - A7. BIOS ver. 4.0j, CRC EC541CD0
//#define SCPH_5500        // DX - D0, AX - A5. BIOS ver. 3.0j, CRC FF3EEB8C
//#define SCPH_3500_5000   // DX - D0, AX - A5. BIOS ver. 2.2j, CRC 24FC7E17 | 2.1j, CRC BC190209
//#define SCPH_3000        // DX - D5, AX - A7, AY - A8. BIOS ver. 1.1j, CRC 3539DEF6
//#define SCPH_1000        // DX - D5, AX - A7, AY - A8. BIOS ver. 1.0j, CRC 3B601FC8

For example, if let's say I have a SCPH-7000 model, then DX is soldered to the D0 pin of the BIOS and AX is soldered to the A7 pin of the BIOS (I attached a picture of the bios pinout above)

What is the key on the chip and how are the legs numbered will not be asked?

And don't forget to uncomment your model in the sketch file

The pinout for the PM41(2) bios looks different than PsNee V7 is that normal ?
