STV VDP-1 update [Mariusz Wojcieszek]

- converted VDP1 drawing (sprites) to use framebuffer

- added sprite priorities (corrects shanhigw ingame and colmns97 title screen)

General Source Changes

----------------------

386 updates [Nathan Woods]

src/cpu/i386/i386.c:

- Implemented usage of segment limits (or whatever they are called)

- Implemented 16-bit interrupts

- Initial values of IDTR are now properly specified

- i386_interrupt() is no longer called when i386_set_irq_line() is

called with a state of zero

- Actual cycle count is now returned

src/cpu/i386/i386op16.c:

- Partially implemented far CALL and JMP instruction

src/cpu/i386/i386ops.c:

- Implemented PUSH rm8 instruction

i960 cpu core / disassembler [Olivier Galibert, R.Belmont, Farfetch'd]

SPI Improvements [Ville Linde]

SPI:

- The "old" video hardware (viperp1) does have 3

layers after all, but no rowscroll. Fixed.

386:

- Bugfixed Nathan's REP

Fixed YMF271 pitch [Ville Linde]

improves music in Brave Blade

Fixed small fileio problem [Nathan Woods]

386 updates [Nathan Woods]

- Added a distinction between maskable and non maskable interrupts

(like int 3, illegal instruction etc)

- Added a distinction between invalid and unimplemented instructions.

Invalid instructions raise an interrupt, and unimplemented instructions

call osd_die() for now

- i386_set_irq_line() will no longer raise an interrupt when passed

with state=0

- Various string intructions now use SI/DI instead of ESI/EDI when in

16-bit mode

- Implemented LOCK and RETF

- Fixed a bug in LMSW

- Minor disassembler fixes

Improved PSX sio [smf]

Various DIP fixes [brian Troha]

Gold Medalist (alpha68k.c)

Break Through (brkthru.c)

Got-Ya (gotya.c)

American Horseshoes & Plotting (taito_l.c)

Phil's 'if I get hit by a bus' Namco S22 MLE update [Phil Stroffolino]

TMS32025:

bugfix for lst and lst1 opcodes; the "ignore ARP" hack has been replaced with a better hack, that doesn't interfere with indirect addressing.

Preliminary serial I/O support has been added, to update DRR/DXR on RINT and XINT interrupts. set_irq_line() no longer masks the lines with 0x7; this allows external triggering of RINT/XINT interrupts.

System22 driver changes:

- display list processing is now done by the master DSP

- the slave DSP's in-game graphics processing and "custom render devices" are currently simulated, which works only for Prop Cycle

- support for PDP block-based memory transfers

- support for DSP data/code uploads from main CPU

- support for "Point RAM" and "Point ROM" access

- most self tests are working in Prop Cycle and Ridge Racer (Japan)

- prelim hand-crafted "internal ROMs" for master and slave DSP

- various notes regarding DSP ports/addressing

Dipswitch corrections for Karate Blazers, Turbo Force, Raiden 2 [brian Troha]

Megaplay Improvements [barry Rodewald, GreyRogue]

SPI / 386 Updates [Ville Linde]

- Added the missing keys to E-Jan

showing stuff correctly, and now the i386 core can be

compiled without i86.

- Preliminary Dallas DS2404 (RTC/CMOS) emulation

- Added 93C46 eeprom to RF2 single and RF2 2K. It's

not hooked up though.

- Improved i386/z80 interleaving. This should help

with the small pauses.

- Fixed some stuff in the i386 core. These don't seem

to affect the SPI games, but should help with MESS

386 Improvements [Nathan Woods]

src/cpuexec.c:

- Adds a check enabled when MAME_DEBUG is defined that raises an

error if the CPU core executed a negative cycle count

src/cpu/i386/i386.c:

behavior in Intel docs)
