Ok, I've searched and tried every possible solution and I just can't make it right. I've got a modded PS2 -I ignore which modchip does it have-, model SCPH 70001.
And this is the thing: if a turn on my PS2 with the memory card in it, it gets me the FMCB logo and it freezes there. Installation was easy, gave me no problems at all, and I know it works because I was able to run FMCB features. But in order to do this I need to turn on the PS2 with FMCB installation cd on, from there go to the Configurator, and then choose the app I want to run.
At configurating I followed the FMCB Guide (FMCB Configurator Guide) and many others and none worked. I've read it might be a modchip issue. In that case, can I solve it without knowing which modchip the PS2 has in it?
