Final Fantasy Hacktics

Can someone please help me set up for online play for the psp emulator?

Kinda falls outside our expertise. That's not modding at all so much as just finding a way to do a local connection over the internet with an emulator.

You'd do better to look for communities dedicated to this. I know of one on Reddit - https://www.reddit.com/r/finalfantasytactics/comments/9ox62w/online_multiplayer_community_info_in_comments/?utm_medium=android_app&utm_source=share
