We've got an update on the Virtual Gameboy Advance emulator - the new version is 3.5, and has been ported to Maemo (Nokia's internet tablets) and Unix/Linux. According to the release, the Maemo edition utilizes the touch screen for a joystick. There's also the usual bug fixes and optimizations too.

See Marat's VGBA emulator page for more info (and to download the trial version).
