Help Identifying (what I assume is) PS2 Modchip

[wallydawg]

While cleaning up a PS2 I recently had come across, I noticed some wires coming out the bottom. Further dismantling lead to this:

I assume this is a mod chip, but most of the ones I see listed in shops are solderless, or the soldered ones have motherboards and not just the single chip that I seem to have here. I don't have burned PS2 games "at the moment" but I tried a Playstation 1 backup and that did not work. My wondering about which modchip this is, is to find out where those three unconnected wires go to (if anywhere). Real PS2 Games (blue backed and dvd games) and PS1 games still work.

This is a SCPH-39001 Fat PS2 if that helps narrow down the search any. Thanks!

There's no way that chip will boot a PS2 DVD.
That's a simple PIC chip, which is what PS1 modchips are made from, so it's odd that you can't boot PS1 copies.

Not sure about the mod, but I would guess that whoever did it works in the electronics industry. It looks like they're using high temp Kapton masking tape which is generally used for wave soldering.

Well that certainly explains why it doesn't look like any of the PS2 chips I was looking at. Not really sure why someone would want a PS1 modchip in a PS2 though. I finally did get it to boot some PS1 copies; they don't load up automatically on system startup, but instead give me the red "Please insert a Playstation or Playstation 2 Format Disc" screen, or think it's an audio cd. When it's at the audio cd screen I can just eject and reload the disc and it recognizes as a Playstation game and I can start the game from there.

Probably because a lot of early PS2 mod devices/discs couldn't boot PS1 copies.
