Dynasty Warriors: Strikeforce

[NikoDallas]

the title says all i just can join a city with my bro but i can't play with him cuz its not syncing together and i just want to know how can i fix it, in the normal PSP(not PPSSPP on the phone i even tried in the phone i get error in the game) theres a flag when you select a map, appears after u choose the map but when i try it with him we just cant play on the PC

so i just hope someone who knows how to fix it :/

PS: i forgot to mention that we cant even join the map that we selected it just says unable to prepare quests
