ok, i just gave this a try. ABSOLUTELY BRILLIANT!!!! thank you for this. aside from smoothing out the sound, it's near perfect. unless i missed something, here's what i recommend:
* ability to rotate the screen; that way i can use the n800 buttons more easily.
* have it remember what the last folder it was that i was in; i have to keep navigating to my mmc for a game
* capability to remap buttons while still pbeing able to use touchscreen; for example, i want button A to be physical button and button B to be the touchpad

so, nice job! btw, i really like how you set up the touchscreen btttons --- especially the combined a+b buttons.
