In April I wrote a post on. This is a similar post, but covering anSCPH-7501 PlayStation 1 MM3 modchip installation. An MM3 modchip allows the PlayStation to boot directly to game backups burned to CDs. MM3 modchips also allow you to run games from other regions. You can buy an MM3 chip for not a whole lot of money, they’re around $4-10. Cost primarily depending on how long you want to wait for your chip. Buying a chip from China is cheaper, but takes longer to arrive.
I purchased my chip from a US seller on eBay preprogrammed and prewired for $8 shipped. This post covers the SCPH-7501 PlayStation 1 console with the PU-22 NTSC board inside. Sony released many different versions of the PlayStation, if your model is different you’ll need to find another guide, or at least a different wiring diagram. Things you’ll need Here’s a list of items you’ll need for your MM3 modchip installation.
In my case the MM3 chip I bought from eBay already had wire preinstalled, so I didn’t need to add the wire. PU-22 PlayStation. If you want to save some money you can actually buy a PIC12C508A chip, and program it yourself. The chip costs a little over a dollar, and a programmer costs about $50. Powerdirector text packages. So if you already have a PIC programmer, or you’re going to be installing a lot of chips, it might be worth looking into.
I’m looking into making MM3 chips which I can sell on eBay since it seems like a decent way to make some extra money. There are also AVR/Arduino sketches which can be used for a modchip, which I may look into in the future. An ATtiny chip for around a dollar, along with an Arduino (to act as an ISP programmer) which you probably already have, might be a cheaper alternative to a PIC based modchip. Installing the modchip The actual PlayStation MM3 modchip installation is pretty straightforward. You’ll need to solder wires to seven points on the top of the console’s motherboard based on the diagram of the motherboard above, and the diagram of the MM3 chip below.
Pin one corresponds to the pin with the circle near it, or the pin to the left of the notch. My board had a large metal shield covering most of the board. To access the points you’ll need to solder to the shield needs to be removed.
Heat up each of the points individually while lifting the parts of the shield off of the board. Unetbootin for windows 7. You can leave the solder on the board for reattaching the shield. I heated up and applied a little bit of extra solder to each of the eight points to make soldering a little bit easier. Make sure you strip only a very small amount of insulation off of the wires so that you don’t have to worry about shorting any nearby points.
Also shorten the wires as much as possible to prevent extra interference. If you are having trouble with your modchip, and your soldering is good, there’s a decent chance your wires are too long. I found the modchip installation to be very easy. All of the points you need to solder to are just small pads. There aren’t any surface mount components, or legs of chips to solder to, like what is required to install a modchip in some other consoles. Pin four on the board can be slightly confusing. The diagram doesn’t give any context as to where it is.
The image above gives a better idea of where this point is, it’s the one in the top left. Putting everything back together With the modchip installed you can put your console back together. Start by soldering the metal shield back into place. Below is an image of what the console should look like once the shield has been reinstalled. With the metal shield in place you’ll want to wrap your modchip in electrical tape to prevent it from touching anything on the board. It is important that you decide where you want your modchip to be when the system back together.
In my case I used the hole that the disc drive ribbon cable goes through seen in the picture below. Conclusion The whole process didn’t take a whole lot of time. It only took me around fifteen minutes to install the modchip. The modchip works perfectly. I haven’t had any issues booting any of the games I have tried with it.
I recommend burning your games at 8x speed (or as slow as your drive can go) using the.cue files in ImgBurn. If you are having problems check your soldering, and try shortening your wires if they are much longer than the ones in the images above.

Hey hey people. I had sourced a PS1 modchip long time ago. I am not sure how modchipping on PS1 goes and I think this is one of those generic programmable chips that could be programmed to work as modchip and then sold as is. I forgot what model the PS1 I took the modchip out from was (it was broken in some manner for sure) and the chip was quite professionally set with 5 wires, in legs 1,4,5,6,7 if I am guessing how leg numbering goes. The chip I have is 'M' - maybe motorola 12C508/P, 04 HAP, 9847 I was wondering how I would install this chip to a 5502 PS1 model.
If at all; Since I am also asking is there possibility that the kind of program the chip has isn't compatible backwards with older PS1's or whatnot. If anyone can help, it is greatly appreciated! Attached is a picture of the mod chip in question.
