I have two PS2 consoles. The first one is a PS2 TEST DTL-H50002 and the second one is a slim model SPCH-75004. I want to install FMCB on the slim model. I've burned a disc with uLaunchELF which I can boot with my TEST PS2. So far so good. Now, when I want to install the actual FMCB build I can't select the menu point "multi install". Is there a way to install FMCB for multi consoles on my TEST PS2? I've tried already some different versions of FMCB. In some older versions I can select "multi install" but then an error pops up. Something with DVDELF.BIN. Can somebody help me? I have no knowledge about PS2.
