Share folders and disk images with a PS2 over the network, straight from a phone, tablet or TV box. The PS2 side is udpfsd with OPL or NHDDL (neutrino).
- Install the apk and grant the permissions it asks for.
- Pick a folder or a disk image in the config.
- Leave Bind IP empty and start the server.
- Boot the PS2 loader. The udpfs device finds the server by broadcast, no server address to type in.
Router in between: connect the box and the PS2 to the same network and give the PS2 an address in the router subnet, e.g. 192.168.1.50 / 255.255.255.0 / gateway 192.168.1.1.
Direct cable: any patch cable works. Set the box ethernet to static 192.168.1.1, netmask 255.255.255.0, gateway empty, and the PS2 to 192.168.1.10.
The PS2 address is required. Set it as udpfs_ip in nhddl.yaml (next to the loader) or in SYS-CONF/IPCONFIG.DAT on the memory card (uLaunchELF: MISC → Configure → Network Settings). Neutrino 1.8.0+ reads the same address from config/bsd-udpfs.toml.
