0.81u8 0000-00-00 [#180 - David Haywood]
----------------------------------------
[private release due to some code cleanups being needed]


New Games supported or promoted from GAME_NOT_WORKING status:
-------------------------------------------------------------
Atari Mini Golf (prototype) [Stefan Jokisch]
Inca (clone of Maya) [ClawGrip]
	
New Non-Working games / clones supported
----------------------------------------
MACS (Multi Amenity Cassette System) [David Haywood] (unknown cpu, seems to be z80 based (16-bit?) with extra opcodes)
Namco FL (Speed Racer / Final Lap R) [R.Belmont] (preliminary emulation (doesn't get very far) to test i960 core)


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]:
	American Horseshoes & Plotting (taito_l.c)
	Break Through (brkthru.c)
	Gold Medalist (alpha68k.c)
	Got-Ya (gotya.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.
