i got this too. i assume we need keys. directory unself looks for keys is the ".ps3" directory under directory pointed to by HOME enviroment variable.
so if HOME is i.e. c:/kdir it will look for dir c:/kdir/.ps3/
do this, create unself1.bat file with this content:
unself.exe ./gt5_eboot/EBOOT.BIN ./gt5_eboot/EBOOT.elf
run it. but it still doesnt found keys, but progress is it gives different error.
"self_decrypt_header failed" instead of "no key found"
anyone got idea what is format of file or files with keys?
Edit: you need to put keys found in keys.rar file download is: "PS3 3.15 / 3.41 / 3.50 lv2 app/iv keys" link in http://www.ps3news.com/ps3-hacks-jai...GT5-Decrypted/
unpack everything and put it in c:/kdir/.ps3/ directory (or directory that matches your HOME env. var. combination i told you in my prev post)
