I have a PS2 modchip available I'd like to be rid of. I bought it brand new, installed it in a system, then un-installed it and sold the system. The chip is a MODBO 745. It was installed in a PS2 slim, but it is supposed to work in all PS2s. It was working 100% fine when I pulled it out, and there's no reason it shouldn't still work fine.
Make me an offer if interested. No, I won't install it in your PS2 for you.
