== Specific Contributions ==
The known contributions for this version are, in the order specified in the whatsnew:

* [[R. Belmont]] improved M37710, NamcoSS22 and C352
** 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

* [[Ville Linde]] improved the SPI driver:
** Improved (but not yet correct) tilemap decryption
** Preliminary sprite priority support

* [[Ville Linde]], [[Bart Trzynadlowski]], and [[Stefano Teso]] added the PowerPC 403 core: 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.

* [[Olivier Galibert]] and [[Andrew Gardner]] improved Virtua Racing

* [[Tomasz Slanina]] and [[Pierpaolo Prazzoli]] made Hyperstone CPU Core Improvements:
** 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.

* [[Angelo Salese]] updated the Jaleco Mahjong driver: some games are *almost* playable but still have protection issues

* Adjusted Top Speed volume balance

* [[Nathan Woods]] added some misc fixes
** 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

* [[Chris Kirmse]] fixed some Multisession win32 bugs
