First of all, I'd just like to congratulate the team on the amazing progress they've made with DeSmuME, taking it to what I personally believe to be the best overall DS emulator of the bunch right now.
With the kissing up out of the way.. ;P
I've noticed that the emulator has progressed enough to work (at least on my computer) at speeds faster than original. Setting frameskip to 0 had the surprising outcome of making certain games work faster, reporting between 100 and 150 frames per second. The only problem is that there are times when you want your game to run at the original speed, and times when you want to fast-forward over the endless, unskipable intro sequences that seem to plague the DS game library.
So basically, could there be a hotkey that would toggle fps limitation on and off, like frameskip0 seems to do?
