[Help] Config in iphone 8.1 (Pangu JB)

I try to setup it for playing Tearing Saga (PSX) but until now still cant T_T. Anyone can help me? First: I download scph1001.bin from PSX bios and put it to retroarch folder is it correct? Second: I hear someone said that we need to do something with Pangu JB for working, if jailbreak with Taig everything will be okie, but i have so much things for install and copy again (about 50gb already). So anyone can help me to fix it?

Thanks, Năm
