3DNES seems to reset the some settings which should be global such as controller and default viewing mode. This means two things: when you launch 3DNES expect to reconfigure the input back to joystick and re-auto detect the Xbox One controller. Another thing to note is that input and viewing settings seem to be baked into the settings per ROM. Meaning, when you choose a game it seems to override whatever settings you have. This is problematic when opening a completely new game. This is just what I guess is going on. Again, this is an awesome product and I'm overjoyed to have it in my library!
