PSO has been there for me through thick and thin. Thank you Soda for everything you've done, and thank you to all the admins, staff, and players for making such a wonderful community.
I use Steam and add Ephinea as a non-steam game to use Steam Input. This method causes input not to work when PSOBB isn't focused
Caveat: If the second game is also through Steam, it will cause the PSO to take inputs anyways... :(
