Ultimate PlayStation 2 modchip installation guide

Since I sell PS2 modchips on eBay I often get asked for installation diagrams showing how to install a chip into a specific motherboard. This post aims to be the ultimate source of information on PS2 modchips, including how to install them into every version of the PlayStation 2. I may have sent you here if you were looking for installation diagrams, or had questions a bout how to install the modchip. Continue reading and I’ll answer those questions and more.

As of right now this guide is still a work in progress. For the most part the Modbo 5.0 modchip guide section is complete, but the rest isn’t.

Guide structure

This guide is structured into several pages. It’s organized like this primarily so that comments can be more organized and useful for readers.

This page is the starting point of the guide. It includes some frequently asked questions about PlayStation 2 modchips in general, and then links off to more information about each type of chip, and those pages link off to installation guides for each console model.

Guide disclaimer

I’m not a PlayStation 2 modchip expert. This guide has been put together from a combination of my experience, and what I have found online. Many of the sources for PlayStation 2 modding information have gone offline, or are spread out across many forum threads.

My goal is to have a single guide that covers as much information as possible, making it easier for everyone to get solid information about PlayStation 2 modchips. If you have any suggestions, corrections, or additional information, please leave a comment and I’ll be happy to update this guide.

Modchip specific guides

Here’s a list of modchip specific guides, which include links to installation diagrams for each board, and source code to make your own chips.

What is a modchip, and what is it used for?

The idea of a modchip is pretty straightforward. It is typically a small chip or board that is soldered to various parts of a video game console. The chip is programmed with special software that is used to circumvent DRM protection on the console.

In the case of the PlayStation 2 a modchip allows the console to do many new things. Here’s a list of common PS2 modchip features.

  • Play video game backups discs from any region (PS1 and PS2).
  • Play genuine game discs from any region (PS1 and PS2).
  • Boot PlayStation 2 games from a hard drive or flash drive.

A common use of a modchip is to play games from other regions, like Japan, that weren’t released in the United States. With a modchip there is no need to import a console from each region.

PlayStation 2 modchip history

I’ll update this section with more detail in the future.

The very first PlayStation 2 modchips took advantage of disc swapping and boot discs like the GameShark or Action Replay.

Later modchips were able to boot games directly.

More recently memory card based exploits were developed. One of those is called Free McBoot, which was first released in 2008 and continues to be updated today. These memory cards boot homebrew directly from the memory card. They aren’t as useful as full modchips, but don’t require any console modifications. They work with all consoles except the later SCPH-9000x systems which patched the exploit.

Can anyone tell me how to get the modbo chip to play burnt games on my ps2? I think o used to have to hold down a certain button for so many seconds to boot them up?

Could you post the hex code for the 12c508a PS2 v12 laser fix?


Hi, I cannot find the Ps2 PIC Fix files anywhere online, and this seems to be the only place with solid information that I can find. Would it be possible for you to send the files perhaps? Hopefully it isn’t a lot to ask, I just have everything I need but cannot find the files to flash to the chip. Thanks!


Is there a modchip out there that preserves the original look of the PS2 bios? By which I mean, no boot logos or alterations to startup screens, etc. I want a vanilla look PS2 that just happens to run imports/backups.

Modbo 5.0 seems great, but in YT videos I see “Infinity” branding tacked onto the PS2 logo after a game reads. Is it possible to keep the logo with its original look?
