Place your roms in /dev_hdd0/game/FBAN00000/USRDIR/roms/
The first time you run FBANext, a configuration file called fbanext-ps3.xml will be generated. This file will store your current options.
If you wish to change your rom path, edit fbanext-ps3.xml located at /dev_hdd0/game/FBAN00000/USRDIR/ and modify the paths-rom element with the directory you wish. Please include a trailing slash at the end of your path otherwise no roms will be located.
.Zip/.7z/.rar file extensions are supported.
