Source Changes
------------------------
Added a new device type for timers. Where applicable, added a parallel set of timer functions that take a device_config instead of an emu_timer. Added MDRV_TIMER_* macros to define the timers in the machine driver. Implemented both periodic and scanline-based timer variants. Modified Space Encounters and Centipede to make use of this feature. Going forward, this is the preferred way of creating periodic timers. [Zsolt Vasvari]

Renamed *_vbl_cb to *_vblank_callback. [Aaron Giles]

Magicfly updates: [Roberto Fresca]
- Completed the component list & PCB layout.
- Added technical references to register $63 (magicfly).
- Switched crystal to new predefined format.

Funworld updates: [Roberto Fresca]
- Added proper inputs to jolyc980.
- Added temporary patch to allow bypass the "code" screen in jolyc980.
- Updated technical notes.

Changed exidy440_sound_command back to "UINT8." Since it's used by both 8-bit and 16-bit systems, the automatic allocation is not worth it if you need an ugly UINT16 ** cast. Removed deprecat.h from some of the exidy files. [Zsolt Vasvari]

Fixed Air Buster bootleg from reseting because of the watchdog. [Zsolt Vasvari]

The on-screen "Reset by watchdog" message only appears in debug builds now. [Zsolt Vasvari]

Fixed the top screen in the megatech games. [Zsolt Vasvari]

Added internal artwork for Gorf. [Mr. Do!]

Fixed memory leak in clifront.c. [Zsolt Vasvari]

Added a crosshair_set_screen() to allow drivers to control which screen(s) on which crosshairs are displayed. [Nathan Woods]

Made it a fatalerror to registr save state callbacks at the wrong time if the current driver claims to support save states. [Aaron Giles]

Fixed chicken and egg problem with device_start callbacks: [Aaron Giles]

- 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.

Moved per-screen initialization into DEVICE_START and per-screen cleanup into DEVICE_STOP in the core video implementation. [Aaron Giles]

Fixed render_target_get_minimum_size() to return nominal values if no screens are found. [Aaron Giles]

Alpha Denshi major update: [Nicola Salmoria]
- 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
- 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.
- 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
- added percussions to the equites.c games using samples; sound board emulation is still not complete. Cymbal hit and hi-hat are missing; bassline is incorrect, and DAC output should be filtered

Fixed crash in spbactn. [Zsolt Vasvari]

In drawgfx, removed unneeded pen lookups. Did some code formatting clean-up. [Zsolt Vasvari]

Fixed ninjakd2 PCM sample rate to match pcb measurement. [Nicola Salmoria]

Fixed chdman -extract to a physical drive on Windows. [Aaron Giles]

Added return value to video_screen_update_partial() indicating whether or not the VIDEO_UPDATE was called as a result. [Aaron Giles]

Fixed typo in pitnrun frequency. [Corrado Tomaselli]

DIP switch improvements: [RansAckeR]
1945kiii.c, 88games.c and 40love.c: Made use of PORT_DIPUNKNOWN_DIPLOC
40love.c: Made use of PORT_INCLUDE
8080bw.c: Added more dip locations; Made use of PORT_INCLUDE
wilytowr.c: Added dip locations for atomboy/wilytowr; Fixed coin modes
battlane.c, battlera.c, battlnts.c, bbusters.c: added dip locations
battlnts.c: made use of PORT_INCLUDE; fixed unknown dip switch
bbusters.c: added note regarding correct gun calibration
bionicc.c: Added dip locations
bladestl.c: Added dip locations, made use of PORT_INCLUDE
blockade.c: made use of PORT_INCLUDE
beezer.c: Added dip locations
bfm_sc2.c: dip switch improvements, made use of PORT_INCLUDE

Converted the MPU4 driver to use an HD6845, as the Hitachi part was on the PCB, while also using it to generate the VBLANK, rather than hardcoding a value. Added the pulldown resistor to the network, and added all the conditional inputs. Please note that on the later Cabinet Types (Ready Steady Go-1 onwards), the 10p slot is locked out (location of the true register for this is unknown), but the input setting is correct - you have to use Coin 2 or higher to get money in. [James Wallace]

Fixed "garbage" (newlines) in the debugger window when debugging the SH-4 CPU. [Oliver Stoenberg]
