Settings on multiplayer windows not being saved

[eltaara]

Using Qt port in Windows in portable mode.
I have different keyboard and/or gamepad mappings a in each multiplayer window. And whenever I close one, it saves the settings and overwrites the last one closed. So each time I want to play with link I have to reconfigure every mgba window. Could you please add separate settings files for each mgba instance?

I tried to launch two mgba executables (portable mode) from separate folders and the linking did not work but settings were preserved.

Also I believe the savegames and savestates are being overwritten too but I guess this can be fixed by having copy of the rom with another name. It would be nice for each window save into its own files by adding a suffix to name or extension (-x where x is the player number after 1).

Last and minor issue, could be possible to launch another multiplayer window by launching the executable instead of in the menu?

Hope I did not repeat this issue, I searched beforehand but may have missed the keywords. I noticed the open issue about only one focused window receiving keyboard input (this feature should be kept as option) and is a bummer when I don't have a gamepad around. Without this issues mgba linking would be flawless.

Savegames are covered by #106, but the rest is novel.

Also the secondary windows cannot take savestates while using multiplayer, since that would just break linking entirely.
