What the HELL is in my PS2?

[Louche]

I went to install my Duo2 SE chip today, and I disassembled my PS2, which I had to take off the warranty sticker, which had not been voided or tampered with, and find this is on my motherboard.



It looks like somebody did some piece of **** patchwork for what i dunno. There's also a capacitor in the tape. I'm wondering what the hell it is and if anyone thinks it would be a problem to unsolder and rip out, or should i try and solder my chip right on top of whatever it is? It seems very odd since the sticker was still there. Any help would be awesome.
