Setting up multiplayer

From PSP2i Wiki

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 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.

PSP / PS Vita

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.
PPSSPP
  1. In PPSSPP, choose Settings on the home screen → Networking.
  2. 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!

  1. 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.
