FMCB on SCPH-70001 problem with Codebreaker in main menu
I am helping a friend set up FMCB on his PS2. He has model SCPH-70001, and FMCB is up and running. I gave him a copy of my Codebreaker.elf (which is NOT the hacked HDLoader version). When he adds it to his main menu and tries to boot it from there, his PS2 just reboots FMCB instead of starting Codebreaker.
I know it is something about his PS2, because he sent me his exact FREEMCB.CNF file and I booted FMCB with it. The Codebreaker option appeared on the main menu and booted properly when I selected it. My PS2 is an older SCPH-5000x model. To complicate matters, when he uses uLaunchElf to boot the Codebreaker.elf directly, it DOES work. I can't figure out what the problem is, perhaps a conflict with FMCB and his PS2?
Is this a known bug?
