the load state here in my computer is slow,once i did load state in mario 64 n it took (more or less) 20 seconds,in another try it took(more or less) 24 seconds,this is a question of mupen or the problem is in my computer?
No,there is no option currently to turn it off.Instant savestates compressed always.
Speed of the loading non compressed save state will not matter THAT much . Currently it some other problem,that keeps some save states to load 10-20 seconds,and others less than second.And it not related to compression of save state in any way.
I don't really have a problem with saving states, but I have some questions about it:
is it possible to bind a key to save-load states?
is it possible (under linux at least) to run mupen64 directly on a game (fullscreen if possible) and loading a certain state? Something like mupen64 -g KillerInstinctGold.zip - sKIState ?
