I tried looking around but I couldn't find an answer to my specific problem. I installed my new chip. I used the led tester and it tested fine. I can disable the chip with the square button so I am assuming that the chip is working correctly. I downloaded toxic bios so that I can play backed up ps2 games. I loaded the toxic bios cue and bin files on a disc and put it in my ps2. It goes to the system browser screen and the disc shows up there but when I click on the disc nothing happens. What did I do wrong? And how can I tell for sure that the chip is working correctly? Sorry if this question was answered already but I couldn't find it.
