Obscure: The Aftermath networking behavior and workarounds

[hrydgard]

As @anr2me mentions in #19896, this game is a bit special.

If the WLAN switch is off, everything is ok, it doesn't connect, it just for some reason spams sceAdhocDisconnect every frame, which returns an error. This leaves PPSSPP in a good state, you can use save states etc.

However if you turn on the WLAN switch, even if you're playing alone, it'll connect to the adhoc server waiting for connections, and PPSSPP will think that you're online, and disable save states and speed controls.

This might be confusing to people, although the game is of course still fully playable without save states, so I'm not sure if it's a big deal really - the workaround is as simple as turning off the WLAN switch anyway.

We could use a compat flag to do a workaround for this game to always allow savestates, although that would be problematic if the player actually wants to play online as the normal safeguards would be off. Not sure if we should do something here.

May be we should just shows a warning that savestate/ff will be disabled if WLAN is on for this game, in case the player enable it without realizing it.
