Theory of operation

OSD controls
------------
There are three types of controls that the OSD can provide as potential
input devices: digital controls, absolute analog controls, and relative
analog controls.
Digital controls have only two states: on or off. They are generally
mapped to buttons and digital joystick directions (like a gamepad or a
joystick hat). The OSD layer must return either 0 (off) or 1 (on) for
these types of controls.
Absolute analog controls are analog in the sense that they return a
range of values depending on how much a given control is moved, but they
are physically bounded. This means that there is a minimum and maximum
limit to how far the control can be moved. They are generally mapped to
analog joystick axes, lightguns, most PC steering wheels, and pedals.
The OSD layer must determine the minimum and maximum range of each
analog device and scale that to a value between -65536 and +65536
representing the position of the control. -65536 generally refers to
the topmost or leftmost position, while +65536 refers to the bottommost
or rightmost position. Note that pedals are a special case here, the
OSD layer needs to return half axis as full -65536 to + 65536 range.
Relative analog controls are analog as well, but are not physically
bounded. They can be moved continually in one direction without limit.
They are generally mapped to trackballs and mice. Because they are
unbounded, the OSD layer can only return delta values since the last
read. Because of this, it is difficult to scale appropriately. For
MAME's purposes, when mapping a mouse devices to a relative analog
control, one pixel of movement should correspond to 512 units. Other
analog control types should be scaled to return values of a similar
magnitude. Like absolute analog controls, negative values refer to
upward or leftward movement, while positive values refer to downward
or rightward movement.
-------------
Game controls
-------------
Similarly, the types of controls used by arcade games fall into the same
three categories: digital, absolute analog, and relative analog. The
tricky part is how to map any arbitrary type of OSD control to an
arbitrary type of game control.
Digital controls: used for game buttons and standard 4/8-way joysticks,
as well as many other types of game controls. Mapping an OSD digital
control to a game's OSD control is trivial. For OSD analog controls,
the MAME core does not directly support mapping any OSD analog devices
to digital controls. However, the OSD layer is free to enumerate digital
equivalents for analog devices. For example, each analog axis in the
Windows OSD code enumerates to two digital controls, one for the
negative direction (up/left) and one for the position direction
(down/right). When these "digital" inputs are queried, the OSD layer
checks the axis position against the center, adding in a dead zone,
and returns 0 or 1 to indicate its position.
Absolute analog controls: used for analog joysticks, lightguns, pedals,
and wheel controls. Mapping an OSD absolute analog control to this type
is easy. OSD relative analog controls can be mapped here as well by
accumulating the deltas and bounding the results. OSD digital controls
are mapped to these types of controls in pairs, one for a decrement and
one for an increment, but apart from that, operate the same as the OSD
relative analog controls by accumulating deltas and applying bounds.
The speed of the digital delta is user-configurable per analog input.
In addition, most absolute analog control types have an autocentering
feature that is activated when using the digital increment/decrement
sequences, which returns the control back to the center at a user-
controllable speed if no digital sequences are pressed.
Relative analog controls: used for trackballs and dial controls. Again,
mapping an OSD relative analog control to this type is straightforward.
OSD absolute analog controls can't map directly to these, but if the OSD
layer provides a digital equivalent for each direction, it can be done.
OSD digital controls map just like they do for absolute analog controls,
except that the accumulated deltas are not bounded, but rather wrap.
