Converted Centipede, as an example.
To define a scanline timer, use something like this:
MDRV_TIMER_ADD("32V", SCANLINE, generate_interrupt)
MDRV_TIMER_SCANLINE("main", 0, 16)
The first number is the first scanline the timer will fire on, the 2nd number is the increment.
So in this case, the timer will fire on 0, 16, 32, ..., 224, 240, then wrap around
because the screen is defined as 256 lines high.
The current scanline is passed to the callback in its 'param' argument
suffixed with _func. Did this throughout the core and
drivers I was familiar with.
Fixed gcc compiler error with recent render.c changes.
gcc does not like explicit (int) casts on float or
double functions. This is fracking annoying and stupid,
but there you have it.
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.
