@romin youll at least need a good memory card (sony or good 3rd party that supports magicgate encryption), and a fat32 usb drive.
everything is kinda on consolemods wiki, but youll quickly leave the site for old ass forums as usual. my only recommendation is to not use freehdboot, it takes over 30 seconds for the console to just turn on. freemcboot is near instant.
id also say try hdd loading, despite my bad experience i feel like its a "doesnt work on my machine" situation.
if you want to do SMB then youll need a spare raspberry pi or something that can turn an ethernet port into a router. i ended up using the psx-pi-smbshare repo but honestly all you need to do is samba and automount usb drives.
