This section has photos of some successful installations which you can use to get a better understanding of how everything is wired and positioned. Flatten the legs of the chip so it can more easily fit underneath the board.Placing the chip in between the circles for pins 3, 5, and 6 seems to be the ideal location.The high speed clock line (pin 2) needs to be especially short and carefully routed.Cut your wires to be as short and direct as possible.Here are some tips I have for you when you are soldering your chip into the PU-18. Just don't apply too much pressure or you might knock the capacitor off of the board. PU-18 Mayumi v4 modchip installation diagramĪll of the points are fairly easy to solder to, with the only tricky point being pin one. I purchased the PIC12C508A-04P directly from Microchip and loaded the Read more.This board was used with a wide range of consoles from the SCPH-5000's, and SCPH-5500's, to even some SCPH-7000's and SCPH-7500's.įor more information about Mayumi v4 chips click here, for more information about PS1 modchips click here. ![]() Im happy with the solder joints but Im questioning whether I used the correct chip. What Im seeing is that the white background boots up with the backup disc and then moves to the Memory cardCD player screen and normal discs continue to operate fine. MM3 MODCHIP SCPH 5501 DIAGRAM MODWith that being said I am having some difficulty with my first mod with the PU-18 using the first circuit diagram provided with all seven wires used including pin 4. MM3 MODCHIP SCPH 5501 DIAGRAM CODEPlaystation Bios Scph 5501 Code Of TheĪfter checking the source code of the firmware, pin 4 is indeed used in multiple parts of the code. Youll need to either use RGB cables or do a dual frequency oscillator mod. Only the PAL games show in color whereas the NTSC games show in blackwhite. High quality CD-Rs were kinda expensive then, like aprox. Otherwise the PS1 would fail to boot the game and go directly to the menu after the boot animation, as if no disc was present at all. The thing absolutely hated cheap CD-Rs and even the ones of good quality needed to be written on low speeds (4x max). The fact that the chip was on a board kind of makes it feel like it may have been a factory mod all along. If you reckon it should be okay to just remove the existing chip without killing the board Ill just go down that route and carry on with the MM3 as per the diagrams. I could definitely have a go if you could tell me what to look for. You could also look around the board for spots that look soldered to. If you could use a multimeter to find out which pin on the chip connects to the red wire I might have a better idea of what it should be connecting to. Theres 6 wires on the chip but one (red) is disconnected and Im not sure whether it was like this before I opened it up or whether Ive inadvertently knocked it off somewhere along the way.Ī little help regarding what this chips function is and where to proceed from here would be greatly appreciated, thanks. Generally you want to use the one thats closest to the chip. ![]() ![]() MM3 MODCHIP SCPH 5501 DIAGRAM INSTALLThe PS works without the chip but when I install the chip it wont read disc. This is an artifact of older non stealth chips that couldnt play anti modchip games without the chip being disabled first.

It does not work on an unmodified system. Just dont apply too much pressure or you might knock the capacitor off of the board. These chips can only be programmed once, so you cant reprogram them.
