Removed weird use of color table in favor of a direct palette
map. It is still a weird abuse of color, but at least it is
done internally and doesn't have the terrible slowdown behavior.
This is still WIP bug I've been working on it for sveral weeks and I want to get it out before leaving for holidays.
- Fixed Alpha 8201/830x MCU simulation.
- all hacks from the equites driver removed
- fixed equites restart position after going underground
- fixed hvolume, splndrbt 2 players
- removed hacks from exctsccr2
- fixed CPU gameplay in shougi
- Gekisou promoted to working
- added dump of Alpha 8201 MCU to games that use it (the ROM isn't used yet, HMCS44 CPU core needs to be written first)
- major cleanup of the mess in equites.c:
- many thanks to Corrado Tomaselli for precious hardware info.
- implemented bg perspective scrolling using PROMs
- fixed sprite flip & disable
- fixed bg color
- converted bg to tilemaps
- fixed fg banking
- fixed screen flip
- removed meaningless banking of player inputs
- added UI adjuster for MSM5232 frequency
- MSM5232 volume control
- fixed MSM5232 noise LFSR formula (done by Jarek Burczynski; thanks to Corrado Tomaselli for samples)
- changed MSM5232 emulator to output channels separately
- added output of SOLO channels to MSM5232 emulator.
- mametesters bugs fixed:
- 00217 splndrbt: On boot the pcb displays a clean light blu screen while in mame there is a black road.
- 00220 splndrbt: Concerning the gfx, on the pcb the background is not linear as shown in mame.
- 00223 splndrbt: On the first level when you pass the asteroid belt the star road should be light blue instead of black like mam
- fixed champbas inputs
- merged talbot with champbas, some driver clenaup
- fixed shougi inputs
- switched exctsccb to use the correct gfx ROMs (matches screenshot found in 01058 exctsccb: Exciting soccer bootleg should be placed in champbas.c.)
- fixed sprite bpp in exctscrr, removed the horrible hacks that were used to fix colors and transparency.
- fixed sound clipping in exctsccr
Crash when loading an autosave save state.
Removed excessive dirty tracking. This creates a bit more
work on each update, but gets rid of some dodgy logic.
Added typedefs for 'struct xxxx' to simply 'xxxx'.
refresh information from the device's inline_config, since this is
done before the screen devices are start. Fixes 01491: switchres
causes Exception at EIP=009413BF: ACCESS VIOLATION.
Also, fixed render_target_get_minimum_size() to return nominal values
if no screens are found.
Added DEVINFO_INT_TOKEN_BYTES, which is queried before device
startup. It should return the size of the structure that will
be hung off of device->token. It must not return 0.
Changed the core device interface to allocate and zero a block
of memory the size of DEVINFO_INT_TOKEN_BYTES before calling
device_start. The pointer to this memory is already attached
to device->token at the time device_start is called.
The primary motivation for this is to allow the device_start
function to make internal calls and pass the device_config *
around as if the object were fully constructed. Since the token
is used to indicate whether or not a device is live, this makes
the device "live" at the time device_start is called rather
than after it completes.
I applied the same fix to verifyroms. Now a status message is printed for every sample/ROM set regardless if an individual or all the sets are audited.
My fix is a bit heavy handed. The real access violation happens in update_digital_joysticks() after the comment "read all the associated ports" and before the next comment

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
