Ah, in GMU select+l/r = skip 10 seconds. Thank you for the link, now I don't have to try and figure out all the shortcuts by myself!
BTW, about the battery, I?ve played gba - minish cap for about 2-3 hours yesterday, and when I woke up it was still 2/3 of the battery remaining. Now I've been playing for about an hour and the battery dropped to 1/3.
I still think that about 12-13 hrs of music and then 3 hours gba is great. And I'm "only" down to 1/3.
Here I was, worried that the battery wouldn't last for more than a couple of hours. (Although I am using the screen set to the lowest brightness.)
Update: I played about another half an hour and the battery died. I guess gaming draing a lot more power than music (naturally) but maybe my battery isn't as great as I thought. I'll have to see how long I can play with afull battery next time.
Did I just loose my game now? Is there a way to get a warning like, a minute before it turns off?
