@ -32,7 +32,7 @@ There are two kinds of numbers in MAME layouts: integers and floating-point
numbers.
Integers may be supplied in decimal or hexadecimal notation. A decimal integer
consists of and optional # (hash) prefix, an optional +/- (plus or minus) sign
consists of an optional # (hash) prefix, an optional +/- (plus or minus) sign
character, and a sequence of digits 0-9. A hexadecimal number consists of one
of the prefixes $ (dollar sign) or 0x (zero ex) followed by a sequence of
hexadecimal digits 0-9 and A-F. Hexadecimal numbers are case-insensitive for

active-low. If the result is non-zero, the state is 1, otherwise it's 0. This
is often used to allow clickable buttons and toggle switches to provide visible
feedback. By using ``inputraw="1"``, it's possible to obtain the raw data from
the I/O port, masked with the ``inputmask`` and shifted to the right so that the
least significant one bit of the mask aligns with the least significant bit of
the value (for example a mask of 0x05 will result in no shift, while a mask of
0xb0 will result in the value being shifted four bits to the right).

When handling mouse input, MAME treats all layout elements as being rectangular,
and only activates the frontmost element whose area includes the location of the
