+*Controller input on classic 16 bit computers is fairly limited.  JoeyLib abstracts to a common API as best as it can.  More details will be coming as the Amiga and ST backends are completed.*
+
+#### jlGameGetAxis
+```c
+int jlGameGetAxis(byte which);
+```
+Returns a value between -128 and 127 with 0 representing the centered position.  Axis 0 is the horizontal (X) axis and axis 1 is the vertical (Y) axis.  On systems with analog controllers, the result will vary depending on how far the axis has moved off center.  You will need to take into account a small "dead zone" for sticks that do not have a precise center position.  On platforms with more than one analog stick, JoeyLib uses the left-hand stick.  If the platform supports more than one controller, all connected controllers at application startup will be used.
+
+#### jlGameGetButton
+```c
+bool jlGameGetButton(byte which);
+```
+Most platforms support two or more buttons.  JoeyLib limits button input to two.  *How to handle platforms with a single button has yet to be decided.*
