Networking

Joining a network

1. On the shelf, press START, go down to Network and press A.
2. On Wi-Fi, press A (or Left or Right) to switch it on. AVAILABLE NETWORKS lists the network joined and the saved ones; press X to look for the others in reach (the bar says X SCAN). omega-zero looks only when you press X, once each time, which saves battery.
3. Pick yours and press A. If it needs a passphrase, type it on the keyboard (see Controls) and press START.

Each network in the list shows its signal, a padlock when it needs a passphrase, and CONNECTED, JOINING or SAVED. omega-zero remembers each network you join and joins it again at the next boot, as long as Wi-Fi was left on. Y forgets the saved network under the cursor; the bar along the bottom says Y FORGET while it can. Settings shows the network joined beside Network, and the top bar on the shelf lights the Wi-Fi icon and ssh while one is joined.

Wi-Fi, Network Time and SSH are each ON or OFF: A, Left or Right switches them. Y on any of the three opens its own panel (the bar says Y INFO there), and B comes back to the row. Wi-Fi's panel shows:

Line	Says
NETWORK	The network joined; a long name is cut short
SIGNAL	Its strength in dBm: the nearer 0, the stronger
IP	The handheld's address
HOST	Its name, such as rg35xxsp.local
MAC	The Wi-Fi radio's hardware address, for a router that only lets in devices it knows

Until a network is joined and has given the handheld an address, the panel says what comes first.

The networks are kept on the card in Config/wifi.conf, in wpa_supplicant's format. You can add one from a computer:

network={
	ssid="My Network"
	psk="my passphrase"
}

The passphrase is stored as plain text, like BaseOS's SSH password, so keep that in mind before lending the card out. Networks that need a username (enterprise Wi-Fi such as eduroam) are not supported.

Copying games over SSH and SFTP

BaseOS runs an SSH server with SFTP. On Network, the SSH row switches it ON or OFF with A, Left or Right: ON starts the server, OFF stops it (logins already made stay), and omega-zero keeps your choice across restarts. Y on the row opens how to log in:

Line	Says
IP	The handheld's address
HOST	Its name, such as rg35xxsp.local
USER	root
PASSWORD	Six random digits, which omega-zero gives root the first time it runs on a card. It keeps them as ssh_password= in baseos.conf at the root of the card in SD1, so BaseOS keeps them too. A password you set there yourself is kept (see BaseOS's settings)
PORT	22

SFTP uses the same login. With no network joined, the panel says to join one first, and with SSH off, to turn it on.

• The card omega-zero runs from is /mnt/sdcard, so games go in /mnt/sdcard/Games/GBA and so on.
• Use any SFTP client, such as Cyberduck, FileZilla or scp.

scp "Metroid Fusion.gba" root@rg35xxsp.local:/mnt/sdcard/Games/GBA/

The name is the model's own (rg35xxsp, rgsp, ...) unless you set hostname= in baseos.conf. If .local names don't resolve on your network, use the address shown.

Network time

Network Time, on Network, keeps the clock right whenever Wi-Fi is joined. The time zone stays the one you chose under Settings > Date & Time. Network Time and SSH are only listed while Wi-Fi is on. Y on the row opens its panel:

Line	Says
STATUS	SYNCED once a time server has set the clock, WAITING until then
DATE	The date on the clock
TIME	The time on the clock
ZONE	The time zone, such as UTC-03:00, set under Settings > Date & Time

With Network Time off, the panel says to turn it on first.
