.... And it seems to have a Matrix chip installed (v1.99) The hard drive included is a 20GB IDE HD. However, when I put the IDE Hard Drive in my PC, it seems to not recognize it, while also using WinHIIP the PS2 HD also wasn't recognized. I wonder what homebrew they did use on it? Only homebrew loads a list of the games installed in the HD and no other commands. PS. Please me merciful on me as I'm a noob on PS2 modification.
