    Misc PS1/2 The PS2 does not memorize settings and cannot set clock

    Damn I fixed it !!!! You'll never gonna believe it ... A resistor was not soldered at the right place !! This motherboard can host 2 types of EEPROM + CLOCK. IC416 or IC 405 + IC 406 (they split EEPROM and Clock for some reason on some models). Mine has IC 416. And if you look at the manual ...

    Misc PS1/2 The PS2 does not memorize settings and cannot set clock

    Looks like it could be more serious than I thought. The clock problem occurred on another of my PS2 (I switch of the power line when I don't use it, and the battery eventually died). However, the problem is not the same. Only clock settings are reset, the console kept language for instance...

    Do you think the 32.768K clock could be dead ?

    The Timer/EPROM chip seems to be correctly powered (PS2 unplugged) :

    Misc PS1/2 The PS2 does not memorize settings and cannot set clock

    Hi everyone, I'm renewing a SCPH-30004R PAL PS2 (GH-015) and I'm facing a very weird issue (looks like I'm attracting them :D). When the console starts, the background is not animated and the console language is English. I can change language (I live in France so french it is) but it goes...

    Hacking PS1/2 Problem with Modbo 5 on V3 PS2

    Unfortunatly, "W" wire is required. I unsoldered it and the chip is no longer detected. I was not able to find a messiah2 chip online. I guess it's no longer for sale.... The only one I can find is the Modbo 5.

    Hacking PS1/2 Problem with Modbo 5 on V3 PS2

    Unfortunatly it is not resolved. It worked for a bit but after some time, I have the problem again. It's like it happens now when the console is warm, after I played a bit. The BIOS injection fails if the console was in standby mode.

    Hacking PS1/2 Problem with Modbo 5 on V3 PS2

    I wrote too fast, or I was lucky : still have the problem .... It seems to be solved ! The trick is to solder "R" directly to the BIOS chip with a wire as short as possible. I was able to guess what pin it is thanks to your PDF x7l7j8cc. Thanks a lot ! Below the updated diagram.

    Hacking PS1/2 Problem with Modbo 5 on V3 PS2

    For sure it's not a fuse as it works until I go standby. Compatibility is written from V1 to V18 where I bought it. Good news, I have some improvement ! First, the "R" point was at the left of the component on my diagram, on the right of it on yours. And it seems yours is correct as I can get a...

    Exactly... It's like there are 2 BIOS on this board ... Very weird. I'll try the Messiah wiring to see if it's better.

    If what I circled in red is the BIOS, what is it in blue ? I doubt that this console has 2 BIOS chip. Kind of weird though !
