ZSNES board

Since this game lacks the ability to save when playing normally online we have started using save states (and they work suprisingly, last time I tried it the whole thing just crashed for no reason). The only problem is, when I load up the state my girlfriend can't hear sound but I can perfectly fine...

I'm on a desktop with 512mb ddr ram 2.8ghz P4 so the resorce thing isn't a problem. I was just wondering cause Yoshi's Island is the only game that wasn't saving properly, I would beat a castle and it wouldn't save but other games that had you go somewheres to save auto saved it. edit: Thanks grinva...

How exactly do I save in-game with Yoshi's Island?

I beat a castle and it's supposed to save but it never does and I can't just do the save state cause I only play it over the net for my girlfriend but we had another game screw up on us wen we tried that.
