0.86 0000-00-00 [#198 - David Haywood]
--------------------------------------

While there are no new working games in this release it remains
interesting from a technical and development point of view mainly
due to the new PPC core as well as the Hyperstone and 37710 fixes.
It should also be a fairly stable release after the many input changes
which have taken place recently.

Driver Improvements:
--------------------

M37710, NamcoSS22 and C352 improvements [R.Belmont]
	M37710 changes (m37710.diff):
	- Data bus is actually 16 bit, not 8
	- Fixed saving of status register on interrupts
	- Fixed errors in PHB, PHT, PLT, and ANDB opcodes
	- Added XAB, PLB, and ROLB opcodes
	- Fixed IRQ dispatch errors
	- Various get_info fixes

	NamcoSS22 changes (s22.diff):
	- All CPU clocks changed to measured-by-Guru values
	- Handle the changed M37710 bus width
	- Temporarily disconnect shared RAM.  There's a
	problem where the 68020's shared RAM test wipes out
	the 37710's work variables and causes it to crash.  I
	suspect there's a register that halts or resets the
	37710.  (note: Prop Cycle has no POST and doesn't
	cause this problem, but all the other games do).

	C352 change (c352.diff):
	- Remove debug printf that accidentally snuck in

SPI Improvements [Ville Linde]
	- Improved (but not yet correct) tilemap decryption
	- Preliminary sprite priority support

PowerPC 403 core [Ville Linde, Bart Trzynadlowski, Stefano Teso]
	This is basically SuperModel (Sega Model 3 emu)'s PPC
	core minus the FPU and 6xx-series specific
	instructions (that stuff isn't ported to MAME yet). 
	As such, it's passed all manner of synthetic PPC
	torture tests and should be quite reliable for any
	PPC403-based hardware.
	
Virtua Racing improvements [Olivier Galibert, Andrew Gardner]

Hyperstone CPU Core Improvements [Tomasz Slanina, Pierpaolo Prazzoli]
	Tomasz Slanina 
	- interrputs after call and before frame are prohibited now
	- emulation of FCR register
	- Floating point opcodes (preliminary) 
	- Fixed stack addressing in RET/FRAME opcodes
	- Fixed bug in SET_RS macro
	- Fixed bug in return opcode (S flag)
	- Added C/N flags calculation in add/adc/addi/adds/addsi and some shift opcodes
	- Added writeback to ROL
	- Fixed ROL/SAR/SARD/SHR/SHRD/SHL/SHLD opcode decoding (Local/Global regs)
	- Fixed I and T flag in RET opcode
	- Fixed XX/XM opcodes
	- Fixed MOV opcode, when RD = PC
	- Fixed execute_trap() 
	- Fixed ST opcodes, when when RS = SR
	- Added interrupts
	- Fixed I/O addressing 

	Pierpaolo Prazzoli
	- Fixed fetch
	- Fixed decode of e132xs_xm opcode
	- Fixed 7 bits difference number in FRAME / RET instructions
	- Some debbugger fixes
	- Added generic registers decode function
	- Some other little fixes.

Jaleco Mahjong Driver update [Angelo Salese]
	some games are *almost* playable but still have protection issues
	
Adjusted Top Speed volume balance

Changes to the main program:
----------------------------

Misc Fixes [Nathan Woods]
	src/inptport.c:
	src/inptport.h:
	- Fixes PORT_INCLUDE by making the final IPT_END appended within 
	input_port_allocate()
	- Added some MESS specific defaults
	- Spelling fix in IPT_BILL default

Fixed some Multisession win32 bugs [Chris Kirmse]

	midnrun, windheat
	These are to demonstrate the PPC core in action, they contain only very
	preliminary emulation and do nothing more than display the initial test
