When I play any game in PCSX2 from Launchbox, if I press the save state or load state buttons (F1 and F3) it won't work. If I load the emulator first, and load the game, I can use these buttons.
My configuration is I launch launchbox through Steam, then launch what ever game in launchbox. I don't think Steam is the issue, as the save states will work if I either launch the emulator from steam, or open the emulator instead of the game in launchbox.
I rather just be able to open the game in launchbox and have it work, as I use a steam link often and navigating the emulator menus is a pain when doing that.
Update:
After trying again, save states worked for a whole session. About an hour.
I then exited out and went right back in, and it loaded the last state at start up fine, but after that it stopped accepting the commands, either on key board or using the shortcuts on the controller.
It seems like sometimes, the savestate/loadstate buttons will work momentarily upon loading the emulator from launchbox, and then stop accepting those buttons. And other times, it accepts the commands everytime.
Update 2:
I think I figured out a fix, will keep this up in case it helps anyone. Launchbox makes two windows, a PCSX2 window, and the game. If I alt-tab to the PCSX2 window, then back to the game window, it will work for the whole session.
