Added two alternative Xtals and a new machine driver to support the Mystery Number hardware.
New games marked as GAME_NOT_WORKING
------------------------------------
Mystery Number [Roberto Fresca]
----------------
Tank Force (US, 4 Player)
marked as not working. Unmapped controls, comments are in driver.
The currently scanned manual at http://www.crazykong.com/manuals/TankForce.man.pdf is for the 4 player version and shows the pinout. Test mode currently shows all player controls as RED (IE active).
* Converted sysreg_r/w to 8-bit handlers
* Added hack to make network IRQs work; brings some games back to life
UML:
* Fixed STORE opcode description to allow immediate source operands
x86/x64 back-ends:
* Added flag support to SEXT, ROLAND, ROLINS, LZCNT opcodes
PPC DRC:
* Rewrote lswi/stswi as subroutines
* Made accesses to tempdata explicitly dword or qword
* Fixed SRR0 when generating a syscall
* Removed no longer necessary TESTs on extsb/w, rlwinm, rlwnm, rlwimi, cntlzw
* Fixed bug where the SO flag was not being computed for compares
* Fixed flag computations for mulhw/mulhwu/mullw
* Fixed subtlety of shifts between 32 and 63 in srw/sraw
* Fixed mffs/mtfsf to use FP registers
* Fixed mtfsfi to use the immediate value properly
* Now marking terminal count bit in DMA status register
* Added simple symbol table to the UML for improved disassembly
* Changed optional disassembler cache parameter to a drcuml object
PPC DRC:
* Added symbols for most common variables
* Fixed bug in handling XER carry flag for subo. forms
* Simplified flag insertion logic for opcodeo. forms
* Added logic to simplify opcodes as much as possible at the UML layer.
* Removed similar logic in the x86 and x64 back-ends.
* Added stricter parameter validation for registers and mapvars
* Removed explicit flag requests from the shorthand opcodes
* Added optimization function to drcuml which is called at block end
* Added logic to compute the necessary flags based on upcoming opcodes
and only select those flags which are required
* Updated the PPC and MIPS3 DRCs to no longer explicitly specify flags
* Wrote new disassembler based on enhanced opcode info structure.
* Moved disassembler into drcuml.c and removed old code.
* Extended disassembler buffer sizes to at least 256 bytes.
* Added more extensive per-opcode information in preparation for UML
optimization step.
* Made validation more thorough using the extended information.
* Disabled back-end validation for now until it can be revisited
using the new tables.
* Changed GETFLGS encoding so that the mask is in parameter 2 instead
of the flags field.

- 01845: [Core] all games: cheats are broken
- 01846: [Misc.] -CHEAT trigger causes MAME crash with PSX-type CPU drivers
Source Changes
--------------
Updated cheat system
- Locked search region when malloc fails to allocate gigantic memory
instead of fatal error. Also locked zero malloc error in case of
search speed = all memory in 32-bit CPU. And added search region
range checker to lock a search region with a big risk
- Fixed a bug that old code is always converted to specified
separator in enable/disable menu
- Refined new cheat format.
* Rewritten cheat format again. newest format is
":gamename::type::address::data::extend_data:(description:comment)"
Expanded type field now requires 10 bytes (not 8 bytes) and
it divides internal cpu (2 bytes) and type (8 bytes) parameters
* Removed VWrite, VRWrite. The flag of Value Selection is merged
into expanded type field now.
* Added CBit (Condition Bit). This checks bit in read data then
set or clear bit in case of true.
* Rearranged cheat code viwer based on newest cheat format
- Fixed unworking Load Old Format option. If you want to load old or
older format code, set it (default is OFF)
- Renamed functions/structures based on coding guidlines
All structures and included parameters are completed
- Merged resize_*_no_dispose() into resize_*()
- Removed the hack of search region for SH-2 CPU because required
region is now set as expected without this hack
