Check if the "Ad hoc" networking option is enabled in the PPSSPP emulator settings on both devices. Ad hoc mode allows for local multiplayer connections. To access this setting, go to Settings > Networking > Enable Networking/WLAN > Enable built-in PRO ad hoc server.

On the host device (the one starting the multiplayer game), go to Game Settings > Networking and set the "Pro Ad Hoc Server IP Address" to the IP address of the host device. You can find the IP address by going to your device's Wi-Fi settings.
