Error with Kingdom Hearts 1.5 hd remix

·F {PPU[0x1000000] Thread (main_thread) [0x00115d58]} class std::runtime_error thrown: sys_fs_open(“/dev_bdvd/PS3_GAME/USRDIR/KHLauncher/Launcher.mself”): Invalid or unimplemented flags: 010000
(in file C:\rpcs3\rpcs3\Emu\Cell\lv2\sys_fs.cpp:129)

There is no mself support yet but it's on the roadmap, unfortunately it won't go further

Oh ok. Then this is the only error that prevents boot?

Can you please explain me what each letter before a console message mean? (The 'F' in this case)
