It might be because I already knew what it should be doing there, and just assumed that it was.
MAYUMI V4 DIAGRAM SCPH 5501 CODE
I'm honestly surprised I never noticed that before, despite having looked at the Mayumi code many times. Since the MM3 code seems to have been derived from the Mayumi code, it makes sense it would also have the same bug. I suspect this was an error, and it was intended to allow the line to float at this point (especially since in normal operation that line would already be low from the transmission of the last stop bit). If there is an electrical hazard warning on the bottom of the case then it is a.

That's why my code always let it float in between messages so that the tracking would stay more or less correct.īut looking at the Mayumi code you are absolutely right - after sending the SCEx message it explicitly calls a routine that pulls the data pin low. The model can be SCPH-30000, SCPH-30001, 35001, SCPH-30002, 35002, SCPH-30003, 35003, SCPH-30004, 35004 If the marked screw doesn't show up in the expansion bay of your PS2 then please take a look on the bottom of the PS2 case. I don't know for sure, since that's a custom chip made for the PlayStation and no data is available, but I always worked on the assumption that it was an integrator used for the input to the tracking servo. MAKE SURE THAT THE POWER CORD IS DISCONNECTED Search for IC701 IC701 is labeled CXD2545Q. PLEASE REMOVE ALL CABLES FROM THE POWER SUPPLY. You have to disassemble the Playstation 1 completely to get to the mainboard. I don't require it constantly being pulled low, so my code restores normal operation after it's done Sony PlayStation SCPH-5502 - SCPH-5552 BIOS v3.0 ()(Sony)(EU)b 240 Ko Sony PlayStation SCPH-7000 BIOS v4.0 ()(Sony)(JP) 282 Ko Sony PlayStation SCPH-7001 BIOS v4.1 ()(Sony)(US) 280 Ko Sony PlayStation SCPH-7003 BIOS v3.

The other old modchips probably do the same. Likewise, a scratched or wobbling CD will not work anymore, when it should. When this functionality is somehow disabled, worn lasers will skip more / fail to read data. Would I be correct in thinking I would need to adapt the code to map to the new port pins in which case, where would I 'pin out' the DATA line?ĬEI has to be coupled to CEO (working as normal) for auto fine tracking to work. My next query then becomes, which pins should I use? However, I am working with a 'Pro Micro' board rather than a 'Pro Mini', so I assume I will need to adjust pinouts to match the code.

Thanks rama3 your work here is stunning! I think I'll stick with a top-side only install for now with the metal shroud in place, it would only require minimal cable routing to get the Arduino sitting above for easy access! I will go back to using it in a later code update.) (Though if you do that, leave space for one extra wire for the WFCK point. You could do it like this for top side mount: Īlternatively, go for the chip on the backside (ring out the connections) and only route the data wire to the other side, through one of the pcb holes. Unfortunately, SQCK isn't available on the top side as a test point or even a via.
