The control stick is a big problem The control stick for the touch screen controls doesn't vibrate when moved. This causes me to be unsure on how I'm moving the character  often allowing me to fall into a bottomless pits multiple times. Not only that  but when I connected my Moga pro controller to Reicast  all the buttons except the control stick were synced  so I couldn't move Sonic around when playing SA1 and SA2. Other than that  it's not a bad emulator. Please create a sync button for the control stick soon.
