Editing Setting up multiplayer

{{MessageBox|Online server status can be found on the adhoc server status page [https://psp2i.wiki/adhoc.xml here].|This page will display the amount of players currently on the PSP2i adhoc server. Our [https://discord.gg/FeGvdBkrGa Discord] server is recommended for finding other players.}}

Instructions can be found below on how to connect online to other players through PPSSPP. Instructions on how to connect online on PSP and PS Vita will not be provided due to issues with cross play, and most of the community plays on PPSSPP.

Internet-Multi Mode is now defunct, as the online servers for the game were taken offline by ''SEGA'' on 2015-09-29. However, it is still possible to play online through peer-to-peer connectivity, through adhoc servers or gaming VPNs.  This means that multiplayer games must be arranged in advance, for example through the [https://discord.gg/7QrArGAcj3 PSP2i Community Discord].

'''Before playing multiplayer, it is highly recommended to clear both episodes of Story Mode, as without clearing the story, you will not have access to missions or adequate shop items.'''
==Solo multi mode==
If playing multi mode alone, no extra setup is required, and can be done without connecting to any outside sources. The below is also applicable if playing multi mode on PPSSPP on the same system, or physically with multiple PSPs or PS Vitas, although someone will have to form party and then join it.

If playing on hardware, make sure that the WLAN switch or internet connectivity is turned on. You will be able to tell if this is the case in the main menu at the bottom, as there is a small banner that signifies the current status of the WLAN switch.

With this active, go to '''Multi Mode''', choose '''Form Party''', then '''Begin Party Play''', and multi mode will start.}}

# In PPSSPP, choose '''Settings''' on the home screen → '''Networking'''.
# Change your settings on the page to the following:
::: '''Enable networking/WLAN''': On
::: '''Enable built-in PRO ad hoc server''': On
::: '''Change PRO ad hoc server IP address''': localhost
You are now all set up to play multi mode alone!
# In-game, go to '''Multi Mode''', choose '''Form Party''', then '''Begin Party Play''', and multi mode will start.}}

==PPSSPP multiplayer on the same network==
If playing multi mode together on the same network, no extra setup is required, and can be done without connecting to any outside sources.
{{Spoiler|All platforms|
# On the machine that will be hosting, find out its local IP address.
## '''Windows PC''': Open '''cmd.exe''' and type '''ipconfig'''. This will bring up some information, the IPv4 address that starts '''192.168''' or '''10.0''' will be the local IP address. For example: '''192.168.1.15'''
## '''Android''': This may differ from device to device, but the usual way to find this out is to go to '''Settings''' → '''About device''' → '''Status'''. On this screen, the IP listed under '''local IP address''' is the device's local IP address.
## '''Steam Deck''': In desktop mode, click on the system tray network icon in the bottom right corner of the screen. Then, click on the active connection, click on details, and the address under '''IPv4 Address''' is your local IP address.
# In PPSSPP on all systems, choose '''Settings''' on the home screen → '''Networking'''.
# Change your settings on the page to the following:
::: '''Enable networking/WLAN''': On
::: '''Enable built-in PRO ad hoc server''': On
You are now fully setup to play multiplayer with other players! When going to play with other players, follow the below steps:
# Decide who will host the game.
# In PPSSPP networking settings, all players must set '''Change PRO ad hoc server IP address''' to the local IP address of the host.
# Restart PPSSPP to make sure the settings change.
# In-game, go to '''Multi Mode''' and form/join party as necessary, and you should all be good to go!}}

==PPSSPP multiplayer over the internet==
<strong>Note: We use ZeroTier One for multiplayer over the internet due to simplicity and ease. However, every so often the network requires a reset - if you find you are unable to connect one day, please return here and rejoin on the new network ID.</strong>

<div class="mw-collapsible-content">
: '''Because of how SteamOS handles updates, it is possible that ZeroTier One will require a re-installation after one. If this occurs, only step 3 of the installation guide needs to done again unless the script file is deleted.'''

What you need:
* [https://psp2i.wiki/files/PSP2i.sh PSP2i.sh] - A bash script file that will install ZeroTier One and connect you to the PSP2i server in one click.

# If you have never done it before, open the '''Konsole''' application and type <code>passwd</code> to set a sudo password. Note that inputs are not shown when typing in password fields in Konsole.
# Right-click the '''PSP2i.sh''' file, click '''properties''', click '''permissions''', and make sure the '''Is executable''' box is ticked.
# Right-click the '''PSP2i.sh''' file and click '''Run in Konsole''', input your sudo password and accept any prompts.

If '''200 join OK''' is displayed at the end, everything was successful. If an error message is received regarding ports, run the script again and it will work.

# In-game, go to '''Multi Mode''' and form/join party as necessary, and you should all be good to go!

If you ever wish to disable the ZeroTier One service, use the below commands in '''Konsole''':
* <code>sudo systemctl stop zerotier-one.service</code> - This will stop the service.
* <code>sudo systemctl disable zerotier-one.service</code> - This will stop the service booting up on system launch.
If you ever wish to uninstall ZeroTier One, use the below command in '''Konsole''':
* <code>sudo pacman -Rcns zerotier-one</code>

===Network tips===
<big>'''Leave the ZeroTier network when not playing'''</big>

On Windows and Android, to make the experience better for people and to avoid network strain, it is advised to always leave the network temporarily while you are not playing. This can be done easily from the ZeroTier menu for joining - simply go to the network and leave it - you will always be able to rejoin at any time.

<big>'''Low bandwidth mode'''</big>

It is also advisable to turn on low bandwidth mode. To do this, download [https://psp2i.wiki/files/local.conf this configuration file] and place it in the following location:

'''Windows''': C:\ProgramData\ZeroTier\One<br>
'''Linux''': /var/lib/zerotier-one

Linux will require <code>sudo</code>, to do this, open the terminal where you downloaded the .conf file to, then input the following: <code>sudo mv local.conf /var/lib/zerotier-one</code>

This has no effect on using the network and will reduce latency for yourself and others.

==Troubleshooting==
===A network error has occurred after infinite walk===
'''Windows PC''': Download [https://www.ppsspp.org/files/1_10_3/ppsspp_win.zip PPSSPP 1.10.3] and try again. There is an issue for some players where versions beyond this do not work properly online.

===Allow ZeroTier One through your firewall (Windows PC)===

ZeroTier One will setup inbound and outbound rules for your firewall to allow the necessary ports and applications through, but it is possible your firewall may still be blocking this. You will need to setup some inbound and outbound rules to make sure the IP range of the PSP2i network is being allowed through.
# Open the Windows Settings app.
# Type in '''firewall''' in the search bar, and open '''Windows Defender Firewall'''.
# In the left column, click '''advanced settings''', and a new window should come up with a column that says '''Inbound Rules''' and '''Outbound Rules'''.
# Click '''Inbound Rules''', and click '''New Rule...''' on the right hand side.
# In the next window that pops up, follow the following instructions, using the steps column on the left:
## Set Rule Type to '''Custom'''.
## Click '''Scope''', then tick the two options for '''These IP addresses'''.
## Click '''Add''' next to both boxes, and then '''This IP address range''', and enter 172.23.0.0 in the top box, and 172.23.255.255 in the bottom box. See example image below of the finished result.
## Click '''Action''' and make sure '''allow the connection''' is ticked.
## Click '''Name''' and choose any name for this rule.
# Repeat the above instructions for an '''Outbound Rule'''.
