Hi all, When i go in quick menu -> option, there is some options who are specific of the core.
What I am looking for, is to set this options, specificly for some games, in pcsx, and parallel.
For exemple,: for automaticly enable/disable multitap on pcsx with games who do not have rumble.
At the top of the Core Options menu there is a “save game options” entry.
Use that to create specific options for the game loaded.
haa, ^^
Ok thank you very much ! 
I’m kind of looking some specific options too.
As example, I wan´t to toogle the background layer using the snes9x core. So far I didn´t find any suitable way of accessing nested features of some cores.
